You can display the current snapshots on the system by using the fssnap -i option. If you specify a file system, you see detailed information about that file system snapshot. If you don't specify a file system, you see information about all of the current UFS snapshots and their corresponding virtual devices.
Use the UFS file system-specific fssnap command to view the extended snapshot information as shown in the following examples.

# /usr/lib/fs/ufs/fssnap -i Snapshot number : 0 Block Device : /dev/fssnap/0 Raw Device : /dev/rfssnap/0 Mount point : /export/home Device state : idle Backing store path : /var/tmp/snapshot0 Backing store size : 0 KB Maximum backing store size : Unlimited Snapshot create time : Mon Jul 12 10:37:50 2010 Copy-on-write granularity : 32 KB |
