Issue

System Manager shows snapshots with the size of 0 KB.

  • The same behavior can be observed when viewing snapshots from the command line:

::> volume snapshot show -vserver svm01 -volume volume1
                             
 Vserver  Volume   Snapshot                                  Size Total% Used%

  • Snapshot size changes after creation.

Snapshot space usage can be checked by running the following commands:

        The volume snapshot show command displays information about Snapshot copies

::> volume snapshot show -volume vol_name

The volume snapshot compute-reclaimable command calculates the volume space that can be reclaimed if one or more specified Snapshot copies are deleted.

Note: This can be a long-running task.
::> volume snapshot compute-reclaimable -vserver SVM_name -volume vol_name -snapshots snapshot_name 

For volume snapshot compute-reclaimable command options, refer to the man page
