infinite loop when remounting a btrfs root filesystem read-write
Hi, I''ve run into a severe problem with a btrfs root filesystem (this is on 2.6.39, but other kernel versions seem to behave the same). The filesystem mounts read-only fine, but trying to mount it read-write causes an infinite loop inside the kernel, causing an infinite repetition of the message inode 57783233 still on the orphan list in printk output. To make things worse, btrfsck doesn''t help - it runs for a couple of minutes, prints a couple of errors, then aborts after saying failed to find block number 1974534356992 There appears to be a bad block on the harddisk, but I doubt that sort of overreaction is intended. Is there any way to recover this filesystem short of rsync-ing it to a different box while mounted read-only and reinstalling?
