Dieter, Creating snapshots using cephfs is quite simple...all you need to do is create a directory (mkdir) inside the hidden '.snap' directory. After that you can list (ls) and remove them (rm -r) just as you would any other directory: smiley@server1:/mnt/cephfs$ cd .snap smiley@server1:/mnt/cephfs/.snap$ ls snap1 snapshot-10-13-2013 smiley@theneykov:/mnt/cephfs/.snap$ mkdir right_now smiley@theneykov:/mnt/1/.snap$ ls -l total 0 drwxrwxrwx 1 root root 0 Oct 13 14:38 snap1 drwxrwxrwx 1 root root 0 Oct 16 11:16 right_now drwxrwxrwx 1 root root 0 Oct 16 11:16 snapshot-10-13-2013 Shain Shain Miley | Manager of Systems and Infrastructure, Digital Media | smiley@xxxxxxx | 202.513.3649 ________________________________________ From: ceph-users-bounces@xxxxxxxxxxxxxx [ceph-users-bounces@xxxxxxxxxxxxxx] on behalf of Kasper Dieter [dieter.kasper@xxxxxxxxxxxxxx] Sent: Wednesday, October 16, 2013 11:01 AM To: Gregory Farnum Cc: ceph-users@xxxxxxxxxxxxxx Subject: snapshots on CephFS Hi Greg, on http://comments.gmane.org/gmane.comp.file-systems.ceph.user/1705 I found a statement from you regarding snapshots on cephfs: ---snip--- Filesystem snapshots exist and you can experiment with them on CephFS (there's a hidden ".snaps" folder; you can create or remove snapshots by creating directories in that folder; navigate up and down it, etc). ---snip--- Can you please explain in more detail or with example CMDs how to create/list/remove snapshots in CephFS ? I assume they will be created on a directory level ? How will the CephFS snapshots cohere with the underlaying pools ? (e.g. using cephfs /mnt/cephfs/dir-1/dir2 set_layout -p 18) Thanks, -Dieter _______________________________________________ ceph-users mailing list ceph-users@xxxxxxxxxxxxxx http://lists.ceph.com/listinfo.cgi/ceph-users-ceph.com _______________________________________________ ceph-users mailing list ceph-users@xxxxxxxxxxxxxx http://lists.ceph.com/listinfo.cgi/ceph-users-ceph.com
