When you create a snapshot, both the original pool and the pool where the snapshot is stored must be active.
Specify the Snapshot name, select Snapshot size, select device from the list, and then click CONFIRM.
Minimum size required for a snapshot is 50MB. The newly created snapshot is available in the snapshot list with the status as offline. This snapshot is made online and accessed from the pool list for recovery.
