Yup, that btrfs is pining for the fjords. And last I heard, the recovery tools aren't very good. As long as the underlying filesystem is that broken, it's hard to say what the OSD will do. You can try backup+restore of the data itself (it's just files and extended attributes), but you're probably going to have to re-mkfs it. Ceph should be able to recover the actual data, if you have the usual replicated setup. -- To unsubscribe from this list: send the line "unsubscribe ceph-devel" in the body of a message to [email protected] More majordomo info at http://vger.kernel.org/majordomo-info.html
