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 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.
