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

I tried an (offline) btrfsck and got the following error message: > btrfsck /dev/sdb3 btrfsck: btrfsck.c:584: splice_shared_node: Assertion `!(src == &src_node->root_cache)'' failed. Aborted I use kernel version 2.6.32.2 with builtin btrfs-drivers. Greetings, Michael -- To unsubscribe from this list: send the line "unsubscribe linux-btrfs" in the body of a message to

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

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 all, I''ve been playing with btrfs resize recently and run into strange looking behavior to me. One of my simple test scenario was following: - partition some block device (lets say sda sectors 2-2000 are sda1) - try to create btrfs on top of it (just mkfs.btrfs /dev/sda1) - fill the fs with data - unmount the device - let''s simulate usual mistake here: downsize the

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). But unfortunately the process breaks with: parent transid verify failed on 29896704 wanted 392661 found 395689 parent transid verify failed on 29896704 wanted 392661 found 395689 parent transid verify failed on 29896704 wanted 392661

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

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

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.

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

In trying to track down a weird tree log problem I wanted to make sure that the free space cache was actually valid, which we currently have no way of doing. So this patch adds a bunch of support for the free space cache code and then a checker to fsck. Basically we go through and if we can actually load the free space cache then we will walk the extent tree and verify that the free space cache

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
