Hi, last week i have had crash on btrfs. After powerdown (magic sysrq did not work) i wasn't able to boot - system was running out of memory. I tried btrfsck from another debian system run from usb flash stick, it produced some errors but i was able to mount my filesystem.
hw info dell latitude 13 with ssd disk OCZ-VERTEX2 120GB system info debian unstable with 2.6.39-1-amd64 btrfs-tools 0.19+20101101-1 btrfs filesystem is mounted on /home build on top of (now degraded) /dev/md0 mount info /dev/md0 on /home type btrfs (rw,noatime,ssd,compress,space_cache) i'm running snapbtr every *:12 minutes, crash happened shortly after this, all snap subvolumes are gone. I have seen similar crashes before, on 2.6.38, without any problems after reboot. I'm also using autofs to mount some samba shares from work server , i think, that this kind of crash was affected by autofs, because i remember autofs in kernel oops several times kernel oops (not whole, sorry) http://klepac.cz/btrfs/07062011104.jpg after reboot http://klepac.cz/btrfs/07062011105.jpg after fsck http://klepac.cz/btrfs/07062011106.jpg with regards Libor
