corrupted filesystem. mounts with -o recovery,ro but not -o recovery or -o ro
I have a 4-disk btrfs filesystem in "raid1" mode. I''m running openSUSE 12.3, 3.7.10, x86_64. A few days ago something went wrong and the filesystem re-mounted itself RO. After reboot, it didn''t come up. After a fair bit of work, I can get the filesystem to mount with "-o recovery,ro". However, if I use -o recovery alone or any other option I eventually hit a BUG and that''s that. I''ve tried with up to kernel 3.8.6 without improvement. My first question is this: how I can make it so I can use the filesystem without having to mount it with "-o recovery,ro" from a rescue environment (I have imaged all four drives *and* made a full filesystem-level backup, except for snapshots and some others). My second set of question is: what went wrong initially, what went wrong with the recovery(s), and are there fixes in kernels after 3.8.6 that might be involved? I have *some* logs, and I might be able to share portions of them. I also took a btrfs-image. Using a very recent btrfs-progs git pull, ''btrfs repair ...'' gives me: ERROR: device scan failed ''/dev/sdb'' - Device or resource busy ERROR: device scan failed ''/dev/sda'' - Device or resource busy failed to open /dev/sr0: No medium found ERROR: device scan failed ''/dev/sdb'' - Device or resource busy ERROR: device scan failed ''/dev/sda'' - Device or resource busy failed to open /dev/sr0:

Re: corrupted filesystem. mounts with -o recovery,ro but not -o recovery or -o ro
Using 3.8.8, I tried mounting with "-o recovery" and "-o
recovery,nospace_cache" (which shouldn''t be any different, if
I''m
understanding the kernel sources properly) without any benefit.
Then I tried btrfs-next ( bba653d1207646b17671c6cb9a0629736811848a as
of this writing ) also without being able to mount the filesystem,
except for one big improvement -- it doesn''t BUG/crash the kernel, it
just fails the mount.
As before, "-o recovery,ro" works.
These seem to be the most useful of the messages:

is just one generation back, but btrfs-restore doesn''t seem to want to
let me use it:

Is there a way for me to use btrfs tools to tell the superblock to go
ahead and use backup root #1 in this case?

Re: corrupted filesystem. mounts with -o recovery,ro but not -o recovery or -o ro
I need to know soon if there is going to be anything I can do to rescue this filesystem. I''ve tried 3.7.10, 3.8.[5,6,7,8] and btrfs-next as of ( bba653d1207646b17671c6cb9a0629736811848a ). btrfs-next - at least - merely failed the mount, all of the others failed but also ran into a BUG, requiring a reboot. I *can* mount this with "-o recovery,ro" but nothing else works.
