ZFS Command History (`zpool history`)

Solaris Express Community Release, build 51: In this Solaris release, ZFS automatically logs successful zfs and zpool commands that modify pool state information. For example:

# zpool history
History for 'newpool':
2007-04-25.11:37:31 zpool create newpool mirror c0t8d0 c0t10d0
2007-04-25.11:37:46 zpool replace newpool c0t10d0 c0t9d0
2007-04-25.11:38:04 zpool attach newpool c0t9d0 c0t11d0
2007-04-25.11:38:09 zfs create newpool/user1
2007-04-25.11:38:15 zfs destroy newpool/user1

History for 'tank':
2007-04-25.11:46:28 zpool create tank mirror c1t0d0 c2t0d0 mirror c3t0d0 c4t0d0

This features enables you or Sun support personnel to identify the exact set of ZFS commands that was executed to troubleshoot an error scenario.

You can identify a specific storage pool with the zpool history command. For example:

# zpool history newpool
History for 'newpool':
2007-04-25.11:37:31 zpool create newpool mirror c0t8d0 c0t10d0
2007-04-25.11:37:46 zpool replace newpool c0t10d0 c0t9d0
2007-04-25.11:38:04 zpool attach newpool c0t9d0 c0t11d0
2007-04-25.11:38:09 zfs create newpool/user1
2007-04-25.11:38:15 zfs destroy newpool/user1

In this Solaris release, the zpool history command does not record user-ID, hostname, or zone-name. For more information, see ZFS Command History Enhancements (zpool history).
