As I understand, you are using this partition under Linux and Mac OS X too. Could you share version of Mac OS X? Could you share more details about hfsplus volume? I need to know: 1. Output of "cat /proc/partitions". 2. Output of "mount" for the case of mounted state of the hfsplus volume. 3. How the hfsplus volume was created? 4. What content this hfsplus volume does contain? Maybe, I will need in making dumps of metadata on your volume. Can I ask you about sharing these dumps?

* Re: hfsplus volume suddenly inaccessable after 'hfs: recoff %d too large' 2013-04-04 18:00 ` hfsplus volume suddenly inaccessable after 'hfs: recoff %d too large' Vyacheslav Dubeyko @ 2013-04-04 20:57 ` Hin-Tak Leung 2013-04-05 5:20 ` Michael Fox 2013-04-07 12:12 ` Vyacheslav Dubeyko 2013-04-05 5:01 ` Michael Fox 1 sibling, 2 replies; 11+ messages in thread From: Hin-Tak Leung @ 2013-04-04 20:57 UTC (permalink / raw) To: Michael Fox, Vyacheslav Dubeyko; +Cc: linux-fsdevel Hi Michael, Argh, that looks suspiciously like the recurring problem I have been trying to pin down for the much of the last year. My current thinking is that one of the patches posted a couple of weeks ago might help. That patch addresses out-of-memory conditions in caching of metadata, in a nutshell. I think if (1) the system is under memory stress, (2) one is doing something which transverse the file system very quickly, (3) on a mult-CPU/core system, it is possible to run some mutexed non-re-entrant code in the hfsplus simultaneously without a mutex lock, and therefore get it a bit confused. This idea at least explains why (1) adding an inner mutex lock can delay the problem although supposedly the outer mutex should have prevented more than one copy of the non-re-entrant code from being run and the inner mutex lock should have no effect at all, (2) the on-disk data is always fsck'ed okay - it is just the driver itself getting confused. So I have a few questions for you: 1. You are on a quad-core system, correct? This is according to your /proc/cpuinfo below. 2. You are certainly doing fast file system transversal (updatedb), but are you actually doing it *on top of the hfsplus* file system? I am asking this because updatedb is usually configured not the index removable media under /mnt or /media . But you mentioned you have the hfsplus system mounted under /home - please confirm that and include some more details if you can. 3. How full and populous is that hfs+ file system? i.e. the output of both "df" and "df -i" while it is mounted. Is this your Mac OS X system (root / ) disk? 4. Is your system under memory stress at the moment the problem happens - e.g. you have a web browser with a few hundred tabs open?

I think you're theory may have merit. The macbook looks like a quad-core to the OS but is an i5 with two cores and some hypthread marketing. Maybe I'm an edge case but I symlinked the /mnt/air to /home/m/air and updatedb definitely indexes it when its mounted. df is: Filesystem 1K-blocks Used Available Use% Mounted on /dev/sda2 50266336 32530972 15175368 69% / udev 1969912 4 1969908 1% /dev tmpfs 791416 944 790472 1% /run none 5120 0 5120 0% /run/lock none 1978532 68 1978464 1% /run/shm none 102400 0 102400 0% /run/user cgroup 1978532 0 1978532 0% /sys/fs/cgroup /dev/sda7 80215040 41449996 38765044 52% /home/m/hfsshare /dev/sda5 97656248 75367680 22288568 78% /mnt/air The volume in question is /dev/sda5 df -i is: Filesystem Inodes IUsed IFree IUse% Mounted on /dev/sda2 3196816 586455 2610361 19% / udev 492478 577 491901 1% /dev tmpfs 494633 525 494108 1% /run none 494633 5 494628 1% /run/lock none 494633 2 494631 1% /run/shm none 494633 1 494632 1% /run/user cgroup 494633 10 494623 1% /sys/fs/cgroup /dev/sda7 4294967295 269 4294967026 1% /home/m/hfsshare /dev/sda5 4294967295 35019234 4259948061 1% /mnt/air At the time of the crash I was running virtualbox, gtkwave, firefox and libreoffice which together swallow about five of the system's four gigabytes of memory. Linux is usually pretty good about this, but you could say that the system was under some memory stress. Thanks for your interest in this problem. It's hard to trap if only seen once in each person's lifetime. I'd be happy to try your recent patches -- though unlikely to produce much data since the crash is so infrequent. But, I can run a test plan to precisely stress memory to the full RAM+swap while running updatedb in a loop overnight and see what happens. At least it would be interesting to know if the patch that you think helps is already in the kernel I'm running or not.

My current thinking is that one of the patches posted a couple of weeks ago might help. That patch addresses out-of-memory conditions in caching of metadata, in a nutshell. I think if (1) the system is under memory stress, (2) one is doing something which transverse the file system very quickly, (3) on a mult-CPU/core system, it is possible to run some mutexed non-re-entrant code in the hfsplus simultaneously without a mutex lock, and therefore get it a bit confused. This idea at least explains why (1) adding an inner mutex lock can delay the problem although supposedly the outer mutex should have prevented more than one copy of the non-re-entrant code from being run and the inner mutex lock should have no effect at all, (2) the on-disk data is always fsck'ed okay - it is just the driver itself getting confused. > > So I have a few questions for you: > > 1.

You are certainly doing fast file system transversal (updatedb), but are you actually doing it *on top of the hfsplus* file system? I am asking this because updatedb is usually configured not the index removable media under /mnt or /media .

* Re: hfsplus volume suddenly inaccessable after 'hfs: recoff %d too large' 2013-04-05 5:20 ` Michael Fox @ 2013-04-07 13:54 ` Hin-Tak Leung 0 siblings, 0 replies; 11+ messages in thread From: Hin-Tak Leung @ 2013-04-07 13:54 UTC (permalink / raw) To: Michael Fox; +Cc: Vyacheslav Dubeyko, linux-fsdevel That certainly looks like it is quite full. You mentioned that "symlinked the /mnt/air to /home/m/air" - just to be absolutely sure, which one is the symlink and which one is the "real" location? To be really sure that updatedb did indexed the directory, what number does locate /home/m/air | wc -l currently show? Regarding Slava's request for the superblock, I would probably like to have a look also. There is no personal info in that part of the disk - just disk geometry, level of occupation (the same info as df, basically), but also one possibly interesting piece of info: the number of pieces of the catalog file, and the sizes of the pieces - and similar info of a few other "system files" - are recorded there, so one can get some idea about the level of fragmentation of the file system. I think the more fragmented the catalog file is, the slower searches it gets, and the more likely one encounters the error condition. --- On Fri, 5/4/13, Michael Fox <415fox@gmail.com> wrote: > Hi Hin-Tak.

That's correct - I can trigger the error condition with debug enabled quite reasonably "reliably". I remembered having done that once, I think with catalog and extent debugging on. The problem was that it generated too much information; since I needed to run "du" on a large directory (~million files) to trigger the condition, the catalog debugging info is a few lines per file, and "du" gets at every of the ~million files, so we are talking about dumping a few hundred MBs into /var/log/messages :-(. Hence another reason to switching to dynamic debugging also - so that one can switch on/off per debugging lines. Even that is not ideal. > Thanks, > Vyacheslav Dubeyko. > > > That patch addresses out-of-memory conditions in > caching of metadata, in a nutshell.

I remembered having done that once, I think with catalog and extent debugging on. The problem was that it generated too much information; since I needed to run "du" on a large directory (~million files) to trigger the condition, the catalog debugging info is a few lines per file, and "du" gets at every of the ~million files, so we are talking about dumping a few hundred MBs into /var/log/messages :-(. > Yes, I understand that the debug output can be a huge in size. But we need to to take into consideration only the output near the point of issue's occurrence. So, I think that it is possible to reduce debug output into smaller size. I understand that such filtering can be not so easy task. But we need to localize the issue's reason anyway by means of debug output analyzing.

The hfsplus volume came with the macbook but got resized by OSX before the Linux install, then it got dd copied to a new drive. Then it got resized again by OSX. And there was an episode where I lost the partition table but got it back. I guess something could have gone wrong in all that but this is the first time I have had a crash like this and it's been stable for a few months. The content of the volume is normal OSX stuff. Nothing top-secret. Maybe a few private keys I wouldn't want to post on the internet but I'm happy to provide metadata if you can instruct me how to dump it. My usage under OSX is pretty minimal -- I haven't booted it in months but sometimes I mount it when I'm looking for a file I haven't used in a while and think that it might be there. OSX version is 10.7 Lion.

I need a some time for investigation of crash's output with the goal of achieving a deeper understanding of the issue. Maybe, the dump of superblock of HFS+ volume on /dev/sda5 device can be helpful too for beginning. You can dump superblock by means of "sudo dd if=/dev/sda5 of=./<dump_file_name> bs=4096 count=1". Please, dump the superblock and share it. You can send this dump only on my e-mail address.
