If I'm not mistaken Ceph with btrfs uses snapshots as a way to do transactions instead of using a journal. Who knows, maybe something failed and they did't get cleaned up or something like that, I've never had a look at how it is handled so I don't know what it looks like normally. But post some information on the list if you see something unusual, someone probably knows. _______________________________________________ ceph-users mailing list ceph-users@xxxxxxxxxxxxxx http://lists.ceph.com/listinfo.cgi/ceph-users-ceph.com
