Solaris 10 8/07 Release: 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 Oracle support personnel to identify the actual ZFS commands that were 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. However, this information is recorded starting in the Solaris 10 10/08 release. For more information, see ZFS Command History Enhancements (zpool history).
