Please keep in mind that work done in git does not appear to get backported to the stable updates for releases (such as 3.2.x), in other words you'll have the same btrfs code as in the first 3.2 release. You will need to use RC's (or git) for the current btrfs kernel code. > Particularly when it's used on top of a dmcrypt layer that btrfs was > known to have issues with I believe the issues between btrfs and dm-crypt have been sorted out as of 3.2 (going on an earlier posting of Chris Masons). Returning to the OP's case, I'm surprised that ext4 is able to get anything back and I'd say that's a testament to its long development life (ext->ext2->ext3->ext4) in comparison to btrfs. If that happened on a system I was sysadmin'ing (and it has - losing an entire tray of drives in a RAID array due to controller firmware bugs really spoils your day) I'd be reaching for the backup tapes about now.
