Yes. This has been discussed before. There doesn't seem to be any way to display that information. 'USED' only shows data unique to that snapshot. There's no equivalent to the NetApp displays of "used by this and older snapshots". I don't know how difficult it would be to create such a display. > The difficult I have now is to find out how to get this size without > destroying the snapshots.

No, not when some blocks are in multiple snapshots, but no longer in the live filesystem. Because you are dealing with snapshots and quotas, you may also be interested in the separation of snapshots from the quota considerations of the parent filesystem: <http://opensolaris.org/os/community/arc/caselog/2007/555/> -- Darren Dunham [EMAIL PROTECTED] Senior Technical Consultant TAOS http://www.taos.com/ Got some Dr Pepper?
