Well, I see USEDSNAP 13.8 GB for the dataset, so if you delete ALL snapshots you'd probably be able to get that much. As for "which snapshot to delete to get most space", that's a liitle bit tricky. See rpool/export/home/m...@zfs-auto-snap:monthly-2009-06-28-20:59, which has USED 2.45G? If I understand correctly, it roughly means rpool/export/home/m...@zfs-auto-snap:monthly-2009-06-28-20:59 and rpool/export/home/m...@zfs-auto-snap:monthly-2009-07-05-13:43 has about 2.45G of difference. Note that the space is probably shared/refered to by the previous snapshots as well. This means: - Deleting rpool/export/home/m...@zfs-auto-snap:monthly-2009-06-28-20:59 only probably won't save you lots of space, as the used space would probably be moved to rpool/export/home/m...@zfs-auto-snap:monthly-2009-05-28-08:03 - Deleting all snapshot on and prior to rpool/export/home/m...@zfs-auto-snap:monthly-2009-06-28-20:59 could give you at least 2.45G space. It's somewhat rough guess, but that's the best interpretation I can come up with. > > As far as I know I'm using zpool version 13 (it might be higher - I didn't > upgrade it manually, but I don't know if the updates from /dev repository > would have triggered an upgrade at any point) The system will be capable of new version, but the pool will not upgrade itself automatically. -- Fajar _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
