Hi, I'm currently trying to re-enable my experimental ceph cluster that has been offline for a few months. Unfortunately, it appears that, out of the six btrfs volumes involved, only one can still be mounted, the other five are broken somehow. (If I ever use Ceph in production, it's probably not going to be on btrfs after this... I cannot recall whether or not the servers were properly shut down the last time, but even if not, this is a bit ridiculous.) I cannot seem to repair the broken filesystem with btrfsck, but I can extract data from them with btrfs-restore. If I want to restore this whole thing, can I just run btrfs-restore to recover the files that were on the broken volume, then make a new filesystem on the old partition, and finally copy over the directories and file restored by btrfs-restore? Or will that lose important information?
