Hi, Had a look at the new additions from zpool version 13 but I still don't think it will give me the information I was after. Here is what I have gathered, can someone correct me if I'm wrong?
1. The USED property for a snapshot only includes the data that is UNIQUE to that snapshot. 2. The USED property for a filesystem includes all data that is SHARED amongst two or more of either the filesystem itself or its child snapshots. 3. There is no way to tell how much data would be freed by deleting a particular set of (one or more) snapshots, without actually deleting that set of snapshots. Or in other words, there is no way to tell how much data is shared amongst a particular set of snapshots but not shared with the current filesystem. Maybe an incremental zfs send could be used by counting the number of bytes produced but that is only between two snapshots and is awkward. -- This message posted from opensolaris.org _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
