Operating Systems Solaris Emergency - restore a deleted zfs snapshot Post 302544974 by aixlover on Friday 5th of August 2011 02:57:10 PM

Here is what I've found:

Before deleting the snapshot, both the original ZFS Z and its snapshot showed 130 GB used. After Z's snapshot was deleted, Z shows 500KB used.

Actually our DBA removed almost all of the data in Z. That must be why the snapshot showed as much space as Z used.

After its snapshot was deleted, Z was nearly empty.

Make sense??

Btw, 'zpool history' does not show zfs command history.
