Hi all, Here's a traceback from a failed attempt to mount a btrfs in lvm in luks filesystem. Note that if I mount it readonly it mounts successfully (haven't tried to recover any data as I have recent backups). Yesterday I defragmented both / and /home with: find /home -xdev -type f -print0 | xargs -0 sudo ./btrfs filesystem defragment -c with btrfs-tools v0.19-35-g1b444cd and rebooted a couple of times. And today I got this traceback while trying to mount home at boot time (/ is working ok) btrfsck fails with the following error: couldn't open because of unsupported option features (8). btrfsck: disk-io.c:682: open_ctree_fd: Assertion `!(1)' failed. I'm using a 2.6.39-rc5+ kernel from Linus' tree. If someone needs any extra info, just ask for it, Ill keep the corrupted filesystem for a few days before destroying it. Thanks. -- Elric Milon
