2014/05/27 Visiting Japan #2 Trip Wrapup
π 2014-05-27 00:00 in Japan, Japan2014, Trips
We loved our trip in Japan last year so much that we had to go back and fill in some of the blanks.

This year, I had a bit more advance notice, and had more time to practise Japanese with language tapes, which came in quite handy in remote places like Yonaguni. Starting with somewhere more remote like Okinawa was interesting, and except for Osaka which we didn't see last year, all other cities we had seen the previous year, but not been able to see everything in, so this second visit was great for filling in the blanks we left last year :)

Here are a few random pictures taken over those 3 weeks.

Awesome liquid testing machine in the airport, with this they test your bottle and don't steal your water or juice. TSA, WTF aren't you doing this?


Store attendants training and a pep talk before opening time:


We loved the logo for that company the cat carrying a cat. We gave them our diving luggage in Osaka so that they sent it to our last hotel and we didn't have to lug it around.


How nice for cabs to actually have 2 charging plugs for cell phones :)


All the digital money cards they have, each region had its own and they were mostly incompatible. Now they finally work mostly everywhere, although this bus was an exception and it showed the only 2 cards its old reader could deal with:


I need to revise my charging station system, too many USB devices to charge nightly, that was a bit of a mess :)



French cookies, yummy :)


That one left me speechless. This temple had loaner wheelchairs so that you didn't ride your dirty wheelchair with filthy wheels on their perfect inside floor. To be honest, I find their obsession of no outside dirt at all no matter what, a bit over the top and definitely annoying when you have shoes like mine that take a long time to take in and out.


Japan has hilarious signs, even if you can't read Japanese:



Do not feed the deer, or they'll be very sad :)

Japan still rules for vending machines, available almost everywhere (although that's a lot of trash and there were very few or no places to recycle containers :( ).

Just like last year, trains were a lifesaver for getting around, where well organized, and on time:




Trains kind of drive themselves nowadays, but they still make it look like serious business, with white gloves :)

I wrote a lot of notes and thoughts last year, you can go refer to them, I think the only extra thing I'd add this year is that I loved many things about Japan, but I was dismayed by the fact that most Japanese people still work way too many hours because of peer pressure, and in the end, just stay at the office until they've hit 12H or so, and it's ok to go home.
For those who try to work that many hours, many studies show it's unsustainable and that you end up actually being less productive trying to work that much than having a normal work week. Somehow, I'd hope that Japanese people wisen up to that and switch to a normal work day and get to enjoy their personal lives a bit more with the extra time.

That said, I'll end with a link to this article Japan, and How I Failed to Figure it Out which actually does quite a good job explaining Japan and how different and fascinating it can be.

2014/05/26 Visiting Japan Day 22: Zojo-ji and Tokyo Tower
π 2014-05-26 01:01 in Japan, Japan2014, Trips

And finally we got to our last day in Japan. Jennifer thought she would enjoy the amenities of our hotel :)


I chose to go back to Tokyo Tower since I had gone in 1997, and figured I would see Zojo-ji, a big quiet temple just next to it, wihch happened to also be featured in X-Men's The Wolverine, much of which happens in Japan. It's a great temple, both in size and appearance:










Next, I went to Tokyo tower, just because. It's not a first attraction (obviously, the Tokyo Skytree has stole the thunder), but if you're by Zojo-ji, why not? :)








Odaiba

At the base of Tokyo Tower, there is a small aquarium. It's nothing to write home about, but I figured I'd check it out anyway. It actually had some interesting fish I hadn't seen before, as well as weird nosed turtles :)

After this, I went back to our room and we walked to the Google Office for lunch with friends and a quick tour.

And after that it was time for a bus back to Narita to fly home. A few shots from that bus:



2014/05/25 Visiting Japan Day 21: Yokohama
π 2014-05-25 01:01 in Japan, Japan2014, Trips

After a good night at the Hyatt Tokyo in Roppongi (5mn from the Google office), I had a quick look at the view from our room, but unfortunately we only got the 9th floor, so that view didn't go very far. Our room in Nagoya had been much better :)


After breakfast, we took a train to Yokohama. We started with Chinatown so that Jennifer could go bond with "her people" :) There was a fantastic Tao temple with exquisite wood carvings, paintings, and gold leaf covering. Turns out it was only 25 years old after the previous temple burned in a fire caused during Chinese New Years...

















After walking by the waterfront and witnessing a boat race.





This got us to the Cup Noodle Museum which was a lot of fun. We designed our own cup noodle container, and made a custom flavour by mixing the ingredients of our choice. After that, we learned about its inventor and his life, which was actually quite interesting.
















Next was the amusement park where we took the ferris wheel for nice higher up views,




landmark tower

Just after, we went to the landmark tower next gave much much better high views :)










Last but not least, we went back to Tokyo to meet to Japanese people who invited us to their home for dinner and conversation, and getting to talk with them (in English) was enlightening.

2014/05/24 Odaiba Science Museum
π 2014-05-24 01:01 in Japan, Japan2014, Sciencemuseums
Next, we walked to Miraikan -- National Museum of Emerging Science and Innovation. I thought would be worth an hour or two but that was a big mistake, we ended up spending over 5 hours there, it was that good. I'm not sure how I can put this, but it was the most advanced science museum I've ever seen anywhere: particle accelerators, neutrino detection at the Super Kamiokande (proving that they have a mass), super conditivity with a levitation demo, very deep sea exploration, DNA/SNP taylored medecine, Asimo demo, and more. Seriously, this put all the other science museums in the dust so much, that it wasn't even funny.








They had a demo on superconductivity:

After a night in our smallish room in Shinbashi (but well located), and watching trains go by through the window, Jennifer got to enjoy the yummy Japanese breakfast included with the room before we went to Odaiba. I had heard that Odaiba had a lot of cool things, so we took a train there, and started exploring on foot:





There is an exact copy of the French statue of liberty in Paris as part of a cultural exchange between France and Japan:

Next, we walked to Miraikan -- National Museum of Emerging Science and Innovation. It's a stellar science museum, totally worth going to. Here is a page on it.

By then, we had little time left for the Toyota Megaweb showcase. We only spent 40mn there and it was worth more, but we had run out of time, and that time had been better spent at Miraikan.

After Linuxcon Japan was over, we moved to Ginza and spent most of the day by Ueno Park's museums:














The Tokyo National Museum at Ueno Park is quite good, lots to see, and for a change it was a place where you were allowed to take pictures. I had planned to go to the Natural Science Museum next door again, but we ran out of time, so it'll be for another time:

We were now in Tokyo where I was there for Linuxcon Japan 2014. On the second day, we had a free evening, so we went out to Ikebukuro's Sunshine City.

We took the elevator to the top, sunshine 60, for an awesome clear view after a storm. Sunshine 60 was the tallest building in 1985 and had the fastest elevator in the world .We got to see Mt Fuji for the first time (which is rare in summer):

2014/05/21 My Btrfs Talk at Linuxcon JP 2014
π 2014-05-21 01:01 in Btrfs, Linux
This all started with my trying Btrfs after Avi Miller's talk at Linux.conf.au. I started asking some questions on the mailing list, and since the wiki wasn't up to date on them, I ddi the obvious thing to start updating the Main Btrfs Wiki here and there.

After I had learned a fair amount about Btrfs already I felt others would benefit from a introduction to it, as well as best practises and what features it offers that would make you want to switch, I ended up submitting a talk to Linuxcon. In the process of writing the talk, I learned even more about Btrfs, and wrote some of them on my Btrfs blog while linking or putting the other relevant ones on the Main Btrfs Wiki.



The fancy talk description is here:

The presentation will give you everything you know to get up to speed with btfrs, why you should want to trust your data to btrfs, how it offers a lot of what ZFS offers without the licensing problems, as well as best practices for using it.

I will go into:

  • the basics of administration of a btrfs filesystem
  • How btrfs, swraid, dmcrypt, and lvm fit or don't fit together
  • how to work with a single storage pool and create all your partitions from it without having to ever resize them, or require LVM as a slow and somewhat unreliable block layer.
  • how to have virtually as many snapshots as you want and why you really want this
  • how to do very efficient block level backups of changes only and much faster than rsync ever will
  • how those block backups can be used to deploy OS upgrades at the file level like I explained in my talk on how Google maintains its many servers last year.
  • The video:

    The quality isn't great due to poor lighting, sorry about this, but you get the talk slides here or view them inline below.
    For easier to click on links, you may prefer the pdf version or the libreoffice version.

    2014/05/20 Historical Snapshots of Backups With Btrfs
    π 2014-05-20 01:01 in Btrfs, Linux

    How to manage historical snapshots of backups with Btrfs

    I have a setup where I backup a certain number of machines to a central server. There are multiple ways to do hierarchical backups with btrfs.

    snapshots and rsync on top

    http://marc.merlins.org/linux/talks/Btrfs-LC2014-JP/html/img33.html
  • not great because of COW relationship lost to unix tools,
  • not great because backing up server on another one requires a lot more snapshots of snapshots for btrfs send of old things that never change
  • works for deduping data that partially changes or changes owners
  • cp -a --link + rsync

    http://marc.merlins.org/linux/talks/Btrfs-LC2014-JP/html/img34.html
  • newer btrfs should be ok with many hardlinks
  • du can figure out the data saved
  • you can use hardlinks.py instead of bedup
  • can be transferred via cp/rsync without losing links
  • but hardlinks will not work across subvolumes
  • cp -a --reflink + rsync

    http://marc.merlins.org/linux/talks/Btrfs-LC2014-JP/html/img35.html
  • very nice, does not require hardlinks which you can't do across subvolumes
  • works for deduping data that partially changes or changes owners
  • but totally lost as soon as you copy it anywhere else (unless you use btrfs send)

    2014/05/19 Visiting Japan Day 15: Nagoya Toyota Factory
    π 2014-05-19 01:01 in Cars, Japan2014, Trips
    After seeing the Nagoya Toyota Automobile Museum the previous day, we went to the factory tour the next day. As a heads up, the factory is pretty far from Nagoya city center by trains, it's easily 1.5-2H one way.

    Unfortunately we were not allowed to take pictures in the factory itself, but it was interesting to see how their assembly line worked, namely how all cars went through the same line, and the robots and humans adjusted to the custom build of each car (from cars to minivans) to perform the precise build specifications for each vehicle.

    When I asked our tour guide why Toyoda-San would have written his name in Katakana instead of Hiragana, she had no answer :)



    But at least I was able to take some pictures in the small museum in the factory:

    Their personal mobility device for people needing help to get around:





    Their trumpet playing robot was quite cool too:

    Of course, they had cars on display:

    2014/05/19 Nagoya's SCMAGLEV and Railway Park
    π 2014-05-19 01:01 in Japan, Japan2014, Sciencemuseums
    I had gone to the museum for less than 2H the previous year, and it was agony to see so much with no enough time to see it, so I was quite happy to back for a much longer visit this time.

    The main hall shows the evolution of Japanese trains over time.

    While the shinkansen (bullet train) between Tokyo and Osaka is actually not that fast (a mere 280kph) due to limitations from the train tracks built for much older and slower trains (the French TGV peaks at 350kph on newer commercial lines), the technology is nonetheless impressive, especially the part where it tries to counter lean in turns to go faster on curves that are too sharp for higher speeds.

    They had plenty of simulators for people to play with and demos. There is a long line for the shinkansen simulator, but to be honest I don't think it's that fun or impressive to drive a train :)





    The diaroma showing the shinkansen line going through Nagoya was quite good:







    The displays showing how often the shinkansens run in a single day, and then how they are maintained was quite interesting. Watch the movie if you can:









    Then plenty of time to look inside all the trains:













    Older trains too:







    It was a great visit, really worth the time.

    After waking up in our room with great view on top of the Nagoya train station, we enjoyed the view outside while having breakfast:






    We took the longish journey to the Toyota Factory (about as long as taking a fast train to Tokyo :)), for our toyota factory tour (on its on page)

    Next, due to how long it would have taken to get around with public transport, we took an expensive but much faster cab directly to SCMAGLEV and Railway Park which we had seen quickly last year (1h15), and I thought was definitely worth a longer 3H+ visit.

    Lots of pictures from museums on this Nagoya's SCMAGLEV and Railway Park page


    After a good long visit of the train museum, we went back to Nagoya to pick up our luggage and take a train to Tokyo:






    2014/05/19 Btrfs-diff Between Snapshots
    π 2014-05-19 01:01 in Btrfs, Linux

    Differences between two btrfs snapshots

    When you have historical snapshots, it may be useful to know what changed between 2 snapshots.

    The best way to do this long term is to modify "btrfs send" to compute changes between the snapshots and just output the filelist instead of a stream with data.

    However, until then, there is a hack that shows you files that got added and removed between two snapshots. It's not bulletproof like btrfs send, but it can give you a quick mostly working diff between two snapshots (*it will not show renames or deletes*). See more caveats on this original serverfault post.

    2014/05/18 Visiting Japan Day 14: Nagoya
    π 2014-05-18 01:01 in Japan, Japan2014, Trips

    For most people, Nagoya is a day stopover between Osaka/Kyoto and Tokyo. If you are very limited on time, fair enough, but otherwise there is more to see (3 days worth actually). If you go through Nagoya and do not stop to see the Maglev Train Museum, you are definitely doing it wrong :)

    We got up from in Kyoto and directly went to Nagoya, where we were going to spend one night. I chose a top floor room with view at the Marriott in the main train station, which turned out to be a great call:



    We then started with the Nagoya Castle. It's not the best castle to visit in Japan due to its renovation going on, but still worth a visit if you're there:














    Next, we went to Tokugawa Garden and Museum:








    Next, we went to the Toyota Automobile Museum, which was a bit out of the way:




    Go to the separate page for the Toyota Automobile Museum. . For the rest of the day, after picking up some fish sandwiches for the train ride back :) , we climbed to the top a nearby observation tower (sky promenade) to see the city, and sunset which turned out to be blocked by the tower our room was in :)

    2014/05/17 Visiting Japan Day 13: Kurama to Kyoto
    π 2014-05-17 01:01 in Japan, Japan2014, Trips

    I had originally planned most of a day in Kyoto to do the east side more leisurely, but since we didn't get to see Kurama the previous day, we went around Kurama in the morning (cable car and hiking to a remote temple high up in the woods). Next to the temple, there was also a treasure museum/nature center worth visiting:

    After our walk and collecting our luggage, we took a train back to Kyoto:



    Kurama was nice, but we only got back to Kyoto electric bike rental shop around 13:00, which barely give us 4H to see eastern Kyoto. Anyone who knows Kyoto knows it's totally impossible in a day, never mind 4H, so we pressed on :) We started with Sanjusangendo with its 1001 statues (minus 3 that are on loan to Tokyo, which we got to see later, impressive to say the least):

    many many statues :)

    Then we hiked to Higashiyama street to see Tainai Meguri next to Kiomizu Dera which is now a big mess of renovation. Turns out Tainai Meguri was a bit gimmicky and not worth the trip, but oh well. The shopping street on the way there was fun seeing again though:

    not sure what happened there :)

    Next, we went to Ryozen Kannon which was closed by the time we got to it last year, but for which we saw the buddha sticking out. It's a very nice peaceful temple that has also become a war memorial:






    And from there we worked back up and stopped at temples on the way. Chion-in which was mostly closed for renovation too, so we went to Shoren-in instead. After that we went back to Nanzen-ji because we were not able to climb its wooden gate last year, and that was worth it:




    This time we managed to get in Eikan-do Zenrin-ji just before it closed. Well, the entrance closed 1h before actual closing time, so we kind of snuck in :) It was well worth it, it's not top on any lists, but it actually has plenty of nice things to see, I'm glad we got to see it:


















    Next, we went back to Honen-in which doesn't really close, and is nice and peaceful, except for 3 male ducks fighting over a single poor female :)





    By then it was past 17:00 so we didn't try to go to the Silver Pavillion which we had seen last year anyway, but biked up there, so that we could bike down the Philosopher's Walk (Tetsugaku no michi) back to where I remembered the outdoors tea room with cats was, and sure enough the cats were there :)










    We then went back to Maruyama Park and finished by going through Yasaka Shrine which helpfully does not close, and finished with dinner by Issian Pontocho:














    This was a good day in Kurama and Kyoto thanks to the electric bikes again, not bad for a half day in Kyoto :)

    After getting breakfast, we got our electric bikes at http://www.kyoto-option.com/ , bar none the best place to get electric bikes in Kyoto, with service in Englsh, and extended hours (very early in the morning to late at night).

    We started with Toji, wihch has the highest Pagoda in Japan, but it's actually a huge complex with much to visit:

    Next were Higashi and Nishi Honganji, which were huge and well worth the visit despite the renovation work that's going on:












    We then stoped at Shoseien, a nice garden:





    which then led us to Nishiki Market, wihch was just what Jennifer was looking for :)



    After returning our bikes, we took a couple of trains to Kurama, a village up in the hills north of Kyoto for our Ryokan there:

    I'm not sure Jennifer needed to go anywhere that morning :)


    Then again, when I mentioned breakfast, she was up :)




    After a good breakfast, we went for an early visit of Nara before the crowds showed up. So nice early in the morning.
    We started with Kasuga Taisha, which we had seen before, but it didn't hurt to see it again :)

    Next was Shin-Yakushi-ji:






    We then cut through the park to get to Kofuku-ji, which we didn't have the time to enter last year:











    We then went to Yoshikien again because it's nice and it was on the way :)





    And we figured, what the hell, we had of course visited Todai-ji the previous year, but since we were walking in front of it to get back to our room, we went inside for a peek again:






    Next, we went to Toshodai-ji and Yakushi-ji on our way to Kyoto. My plan was to store our luggage in the lockers by the Kintetsu train station Nishinokyo, but the lockers were too small for my big luggage :( In the end I had to lug it to both temples, but since it was raining anyway, we just took cabs:















    That was a good run for Nara, so we ended there, and took the kintetsu to Kyoto (just 50mn), checked in our hotel across the train station, had a quick loook at Kyoto tower but didn't go up since we were warned it was overrun with kids by the people selling tickets (also the weather was poor), so we went to Kyoto station instead for good views, dinner, a visit of the inside (including the awesome dot matrix display built into the stairs, and back to the room).:














    And this concluded another nicely filled day.

    Nice murals in the train station:




    In the morning, I went to Shitenoji to see an old temple with a pagoda you could actually climb to the the top of (pretty much not possible for most of them):













    I then went back to Osaka station to pick up our luggage and take a train to Nara:


    train driving is serious business :)

    We took the loop line to arrive in Nara by the south so that we could stop at Horyu-ji, the oldest Japanese temple located in Nara. We got super lucky and got a retired engineer who spoke well English and gave us a detailled personalized tour for free:

    After the temple, we went to Nara proper, but got there a bit late to see anything, so after plyaing with the deer, we backtracked to our fancy Ryokan to enjoy the onsen and a yummy dinner















    Except for trying to see a bit of Nara after arriving there instead of just calling it day when we arrived a bit late, we did well :) We just spent more time to finish up Nara the next day

    2014/05/12 Visiting Japan Day 8: Okinawa Aquarium and Ocean Park
    π 2014-05-12 01:01 in Aquariums, Japan, Japan2014, Trips
    During our last day in Okinawa, we got up early and drove north to Ocean Park all the way north on the island, to spend the day before driving all the way back down to the airport.

    The aquarium is 3rd biggest one in the world (#2 is Dubai and #1 is Atlanta), and the only one with 3 whale sharks, and the Expo Park it's in has plenty of other things to see.


    Since we had left early, we entered the aquarium right after 08:30 on a monday morning when it opened, so thankfully we avoided the crazy crowds that can be there.


    The outside flower statues were fantastic:








    There are many displays on fish obviously, but the main attraction is the huge whale shark tank (below):




    giant lobsters, too much to eat for a single person on these :)

    The Aquarium is of course known for its 3 whale sharks (which are actually sharks, not whales). It's the only place in the world where you can see 3 of them, especially of that size. They may actually have the biggest habitat of any aquarium:







    The rest of the aquarium was also good:

    And after over 6H in the park, it was time to head back. We could have spent a bit more, but we got a good overview. Maybe we'll be back one day.

    After Yonaguni, we flew back to Okinawa where the goal was mostly to dive, but while we were there, we got a rental car and went to visit some things around the island.

    This isn't the rental car we picked up, but that was tempting :)


    We first went to the Navy Underground Headquarters where the Japanese Navy generals hid and fought to the death when the US Marines came to take the island. It was both interesting and depressing:

    We started with 2 days in Yonaguni, which was a bit off season (May when peak season is actually until March), so we didn't get to see any hammerheads or whale sharks, but on the flipside, it sure wasn't busy. It actually really was just us in the boat.
    It pretty much rained the entire time, but that's ok we were there for diving. We did 5 dives on the 2nd day for catch up for the 1st day, and 3 dives on the 3rd day (due to the flight back the next day).

    We had a pretty big boat for just the two of us:


    The highlight for Yonaguni was the underwater monument, which looks like an underwater atlantis:

    2014/05/04 Fixing Btrfs Filesystem Full Problems
    π 2014-05-04 01:01 in Btrfs, Linux

    Fixing Btrfs Filesystem Full Problems

    Clear space now

    If you have historical snapshots, the quickest way to get space back so that you can look at the filesystem and apply better fixes and cleanups is to drop the oldest historical snapshots.

    Two things to note:

  • If you have historical snapshots as described here, delete the oldest ones first, and wait (see below). However if you just just deleted 100GB, and replaced it with another 100GB which failed to fully write, giving you out of space, all your snapshots will have to be deleted to clear the blocks of that old file you just removed to make space for the new one (actually if you know exactly what file it is, you can go in all your snapshots and manually delete it, but in the common case it'll be multiple files and you won't know which ones, so you'll have to drop all your snapshots before you get the space back).
  • After deleting snapshots, it can take a minute or more for btrfs fi show to show the space freed. Do not be too impatient, run btrfs fi show in a loop and see if the number changes every minute. If it does not, carry on and delete other snapshots or look at rebalancing.
  • Note that even in the cases described below, you may have to clear one snapshot or more to make space before btrfs balance can run. As a corollary, btrfs can get in states where it's hard to get it out of the 'no space' state it's in. As a result, even if you don't need snapshot, keeping at least one around to free up space should you hit that mis-feature/bug, can be handy

    Is your filesystem really full? Mis-balanced metadata and/or data chunks

    Below, you'll see how to rebalance data blocks and metadata, and you are unlucky enough to get a filesystem full error before you balance, try running this first:

    legolas:~# btrfs balance start -musage=0 /mnt/btrfs_pool1 &
    legolas:~# btrfs balance start -dusage=0 /mnt/btrfs_pool1 &
    A null rebalance will help in some cases, if not read on.

    Also, if you are really unlucky, you might get in a no more space error that requires adding a temporary block device to your filesystem to allow balance to run. See below for details.

    Pre-emptively rebalancing your filesystem

    In an ideal world, btrfs would do this for you, but it does not.
    I personally recommend you do a rebalance weekly or nightly as part of of a btrfs scrub cron job. See the btrfs-scrub script.

    Is your filesystem really full? Mis-balanced data chunks

    Look at filesystem show output:
    legolas:~# btrfs fi show
    Label: btrfs_pool1  uuid: 4850ee22-bf32-4131-a841-02abdb4a5ba6
    	Total devices 1 FS bytes used 441.69GiB
    	devid    1 size 865.01GiB used 751.04GiB path /dev/mapper/cryptroot
    Only about 50% of the space is used (441 out of 865GB), but the device is 88% full (751 out of 865MB). Unfortunately it's not uncommon for a btrfs device to fill up due to the fact that it does not rebalance chunks (3.18+ has started freeing empty chunks, which is a step in the right direction).

    In the case above, because the filesystem is only 55% full, I can ask balance to rewrite all chunks that have less than 55% space used. Rebalancing those blocks actually means taking the data in those blocks, and putting it in fuller blocks so that you end up being able to free the less used blocks.
    This means the bigger the -dusage value, the more work balance will have to do (i.e. taking fuller and fuller blocks and trying to free them up by putting their data elsewhere). Also, if your FS is 55% full, using -dusage=55 is ok, but there isn't a 1 to 1 correlation and you'll likely be ok with a smaller dusage number, so start small and ramp up as needed.

    legolas:~# btrfs balance start -dusage=55 /mnt/btrfs_pool1 &

    # Follow the progress along with: legolas:~# while :; do btrfs balance status -v /mnt/btrfs_pool1; sleep 60; done Balance on '/mnt/btrfs_pool1' is running 10 out of about 315 chunks balanced (22 considered), 97% left Dumping filters: flags 0x1, state 0x1, force is off DATA (flags 0x2): balancing, usage=55 Balance on '/mnt/btrfs_pool1' is running 16 out of about 315 chunks balanced (28 considered), 95% left Dumping filters: flags 0x1, state 0x1, force is off DATA (flags 0x2): balancing, usage=55 (...)

    When it's over, the filesystem now looks like this (note devid used is now 513GB instead of 751GB):

    legolas:~# btrfs fi show
    Label: btrfs_pool1  uuid: 4850ee22-bf32-4131-a841-02abdb4a5ba6
    	Total devices 1 FS bytes used 441.64GiB
    	devid    1 size 865.01GiB used 513.04GiB path /dev/mapper/cryptroot

    Before you ask, yes, btrfs should do this for you on its own, but currently doesn't as of 3.14.

    Is your filesystem really full? Misbalanced metadata

    Unfortunately btrfs has another failure case where the metadata space can fill up. When this happens, even though you have data space left, no new files will be writeable.

    In the example below, you can see Metadata DUP 9.5GB out of 10GB. Btrfs keeps 0.5GB for itself, so in the case above, metadata is full and prevents new writes.

    One suggested way is to force a full rebalance, and in the example below you can see metadata goes back down to 7.39GB after it's done. Yes, there again, it would be nice if btrfs did this on its own. It will one day (some if it is now in 3.18).

    Sometimes, just using -dusage=0 is enough to rebalance metadata (this is now done automatically in 3.18 and above), but if it's not enough, you'll have to increase the number.

    legolas:/mnt/btrfs_pool2# btrfs fi df . Data, single: total=800.42GiB, used=636.91GiB System, DUP: total=8.00MiB, used=92.00KiB System, single: total=4.00MiB, used=0.00 Metadata, DUP: total=10.00GiB, used=9.50GiB Metadata, single: total=8.00MiB, used=0.00

    legolas:/mnt/btrfs_pool2# btrfs balance start -v -dusage=0 /mnt/btrfs_pool2 Dumping filters: flags 0x1, state 0x0, force is off DATA (flags 0x2): balancing, usage=0 Done, had to relocate 91 out of 823 chunks

    legolas:/mnt/btrfs_pool2# btrfs fi df . Data, single: total=709.01GiB, used=603.85GiB System, DUP: total=8.00MiB, used=88.00KiB System, single: total=4.00MiB, used=0.00 Metadata, DUP: total=10.00GiB, used=7.39GiB Metadata, single: total=8.00MiB, used=0.00

    Balance cannot run because the filesystem is full

    If a null rebalance (-musage=0 and then -dusage=0 explained above) doesn't work, one last trick to get around this is to add a device (even a USB key will do) to your btrfs filesystem. This should allow balance to start, and then you can remove the device with btrfs device delete when the balance is finished.

    Note, it's even possible for a filesystem to be full enough in a way that you cannot even delete snapshots to free space. This shows how you would work around it:

    Armin Only in San Jose, 15mn from where I live? OMG, really? My last Armin Only was in 2007 in Holland, and I had to fly there, so needless to say that I bought the tickets 6 months early when they went on sale, and I was definitely looking forward to it.

    This Armin only was only 5h instead of the crazy 9h30 he did in 2006, but honestly it was better because it was 5h of great tunes one after another, no filler songs.
    Once you add the live artists and performances, it was pretty fantastic. You can see a summary here:

    Next, a few auto-awesome pictures from G+:








    And then the real pictures, many courtesy of the 30X zoom on my point and shoot camera:

























    And before I ever had the time to get bored, it was over. A great evening, really:

    2014/05/01 Down The Rabbit Hole Of Trance
    π 2014-05-01 01:01 in Clubbing
    I was listening to Armin's Essential Mix from 2013, another great one you can listen to many times :)

    It starts with some movie bits from a Sci-Fi movie I didn't know, and that felt wrong :) I wrote down some of the lyrics so that I could look them up later:

    Offset 2mn:

  • we are locked in the event horizon
  • Thank you smitty
  • stark give me a read
  • the reactor is still hot, we have several radiation leaks
  • do I have pressure?
  • there is no gravity, reactors are offline
  • brought most primary systems online
  • Offset 10mn:

  • brought most primary systems online, for now
  • stark, what's our status?
  • the antenna array is totally fried. We've got no radio, no laser, no high gain, no one is coming to help us
  • Offset 19mn:

  • She's all right, it's ok. You're safe now
  • Justin! Cooper!
  • They're fine, they're with us
  • Offset 28mn:

  • Look, if what the ... tells us is true, Othis ship has been on the boundaries of our universe of known scientific reality. Who knows where it's been, what it's seen, or what it's brought back with it
  • Offset 2h27:

  • I need to be on that ship
  • Once we secure the ship, we bring you on.
  • I'm sorry, this is unacceptable, I need to be on that ship.
  • Once we secure the ship, that's the way it is. I need you to guide us from the comm station, this is where I need you. Help us do our jobs.
  • I took note of the script bits, plugged them into google and of course it was a known Sci-Fi movie that someone went through the trouble of entirely hand transcribing, so my search was easy.
    The movie was Event Horizon, http://www.imdb.com/title/tt0119081/ , which was an enjoyable watch.

    But that wasn't the end of it, some lyrics in that ASOT were different:

  • At 43mn: Do you know what your problem is? You got nothing to do in your life. Why don't you get a job? Do something... be a nurse.
  • At 2h: We'd like to discuss something that if of interest to all of us here. You have a problem Tony, we have a problem.
  • That didn't take too long to trace to Scarface. I need to watch this again :)

    Last but not least, 1h24mn in,there was a nice quote which I could tell was from Morgan Friedman, and I traced it to Shawshank Redemption, which I had but apparently had never watched, so I watched that too. Great movie.
    "I look back at the way I was then... I young stupid kid that committed that terrible crime. I want to talk to him, I want to try to talk some sense to him, tell him the way things are...". Oh, and at the very end of the mix:

  • We just have to put it behind us... move on.
  • I'm done. Everything stops.
  • Nothing stops. Nothing...
  • Then, while watching Shawshank Redemption, I heard this other great piano tune I already knew, Thomas Newman - Brooks was here: http://www.youtube.com/watch?v=YmjqO7DD14I
    Of course, I had heard it in other Trance mixes before, it's an awesome piano track. Interestingly, the track is called "Compass and Guns" in the movie soundtrack: https://www.youtube.com/watch?v=v04F8_sHLJk

    So I went from trance to movie, which then brought me back to other trance, full circle. I like how it all pieces together, thanks to a few google searches :)
