Dear list members, When I tried to recover my partition from the space cache bug (see http://www.mail-archive.com/linux-btrfs@vger.kernel.org/msg24360.html ), I issued the command `mount -o clear_cache -t btrfs /dev/sda7 /aaa/aaa`. After 10 minutes the mount command segfaulted. I cloned the latest btrfs-progs from Josef''s Github account and ran the `btrfsck --repair` twice on the

Dear list members, Yesterday I was about to restart my computer and that''s why I closed every opened applications: three Eclipse instances, two other Java applications, 2 web browsers etc. It involved a lot of IO operations and before everything could settle down my system became unresponsive. I mean X & co. worked fine, but anything related to IO (opening a new screen, a new

Hi folks! Been using btrfs for quite a while now, worked great until now. Got power-loss on my machine and now i have the "parent transid verify failed on X wanted X found X" problem. So I can''t get it to mount. My btrfs is spread over sda (2tb), sdc(2tb), sdd(1tb). Is this something that an offline fsck could fix ? If so is the fsck-util being developed ? Is there a way to

Heyho! (This is using btrfs from Debian''s 2.6.32 2.6.32-3-kirkwood kernel (-9 package; btrfs tools is v0.19-16-g075587c) A few observations about btrfsck: a btrfsck run on a 2T volume (4 disks) on a QNAP appliance (512M ram) got killed by Mr. OOM Killer. Initially, I was quite surprised. I''m only moderately surprised now since it might well be that I forgot to enable

Hi, I thought that I would attempt a quick little patch that will make btrfsck into a No-op when called as fsck.btrfsck. The reasoning is that the FAQ states that it is recommended and safe to do so, and the current 12.04 version of Ubuntu just symlinks fsck.btrfsck to btrfsck instead of /bin/true. PS - Apologies if I mess this git send-email up! Dan McGrath (1): btrfs-progs: No-op when

Is it expected that running btrfsck more than once will keep reporting errors? Below is the end of a btrfsck output when run the second time. backpointer mismatch on [111942471680 32768] owner ref check failed [111942471680 32768] ref mismatch on [111942504448 40960] extent item 1, found 0 Incorrect local backref count on 111942504448 root 5 owner 160739 offset 3440640 found 0 wanted 1 back

Hello. I am continuing my tests of BtrFS under a practical workload. Recently an incorrect poweroff (or maybe a small bug in BtrFS) caused a small data loss. The actual damage was non-existent. I used old branch, so maybe the relevant code is already improved. 1. Why btrfsck says "bad block" on that partition? What does it mean? My fist reaction was to use badblocks. It found no

I have accidently damaged the first block(s) of a btrfs partition and can''t mount it anymore. I can see that my data is still intact by running a command like: cat /dev/sda5 | hexdump -C | more Do any (experimental) tools exist which would allow me to recover the files?

NOTE: in order to apply this patch you should: git mv btrfsck.c cmd-fsck.c This patch moves btrfsck in to "btrfs fsck". It also adds support for symlinks to the btrfs binary to retain compablity, =) I think something should be done to the help description but i''m not sure what... Anyway, feedback is welcome. -- To unsubscribe from this list: send the line "unsubscribe

Hi All, I''m trying to repair a broken fs using btrfsck and am hitting a failed assertion. I''d appreciate any suggestions for what to do next. Is there any thing I can do to help fix this bug? Any other information from my FS which would help? If the FS could be salvaged that would be a bonus, but I''m more interested in providing a useful bug report before wiping the

A few months ago, my btrfs storage array became corrupted because of a power failure. A while ago, I made this thread to try and resolve the problem. (http://www.digipedia.pl/usenet/thread/11904/15955/) You can find detailed information about the problem in the previous thread, but I am happy to provide any other details. It didn''t really go anywhere in the way of solving my problem. The

So I''m having a bit of trouble with one of my btrfs filesystems. It isn''t mounting after a power failure. I can''t get restore or btrfsck to run, even on backup supers. I''ve pasted some output below. My btrfs-progs below come from git this morning, running on linux 3.2.0. # mount /dev/md2 /media/test/ mount: wrong fs type, bad option, bad superblock on
