How to Display UFS Snapshot Information

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 snapshot. If you don't specify a file system, you see information about all of the current file system snapshots and their corresponding virtual devices.

1. Become superuser.

2. List current snapshots.

   # fssnap -i 0 / 1 /usr

   To display detailed information about a specific snapshot, use the following:

   # fssnap -i /usr Snapshot number : 1 Block Device : /dev/fssnap/1 Raw Device : /dev/rfssnap/1 Mount point : /usr Device state : idle Backing store path : /scratch/usr.back.file Backing store size : 480 KB Maximum backing store size : Unlimited Snapshot create time : Tue Aug 08 09:57:07 2000 Copy-on-write granularity : 32 KB
