similar to: question about btrfsck/mount behavior on corrupted fs

Is anyone interested in some part of this filesystem to figure out how it failed? Or can I erase and start again?

The new xfstests will run fsck against the volume to make sure we didn''t introduce any inconsistencies, which is nice except we will error out immediately if we mount with inode_cache. We need to make btrfsck skip the special free space cache items and then just assume that we have a link for the free space cache inode item. This makes btrfsck pass with success on a fs with inode cache

Hi, I''m having a filesystem that''s been a bit mangled by external causes, so I thought I''d see how much I could salvage (it''s not critical, though). Thus, I pulled btrfsck from git and ran: pannekake:~/btrfs-progs# ./btrfsck --repair /dev/mapper/pannekake-backup-btrfs It spit out a ton of warnings like these (I can get the whole log if you''re

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! We have some btrfs rsync-snapshot backup servers which have been running since about mid-2009, with a pretty good record so far. We''ve been following the development kernels and hitting some bugs here an there, but we still haven''t managed to lose anything yet. The main problems we have ran in to relate to ENOSPC and reporting full when "df" only shows 74% used,

Hi there, after my filesystem is broken (I have no idea why, because last shut down was nomal) I tried to repair it with btrfsck ( Btrfs v0.20-rc1-56-g6cd836d).

After upgrading from 2.6.39-rc7 to 2.6.39 this morning, I tried to mount my 3 disk btrfs volume (no subvolumes, space caching enabled, lzo compression) and received some parent transid errors (going back to rc7 didn''t help, though): btrfs: disk space caching is enabled parent transid verify failed on 6038227976192 wanted 337418 found 337853 parent transid verify failed on 6038227976192

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

Is it expected that running btrfsck more than once will keep reporting errors?

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

Hello everybody, compiling btrfs-progs from current git I get an error in btrfsck.c about undefined references. The attached patch adds an include for sys/stat.h which fixes the problem for me. Regards, Chris

Exec btrfsck on btrfs with snapshots that are under a dropping progress will cause prompt on "ref mismatch". However we do not want this kind of prompt, since an remount operation will continue the dropping progress. Here the prompt is nonsense.
