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% -------- -------- ------------------------------------- -------- ------ ----- svm01 volume1 daily.2017-01-01_0010 5.55MB 0% 0% weekly.2017-01-01_0015 3.05GB 0% 0% daily.2017-01-04_0010 0B 0% 0% daily.2017-01-05_0010 0B 0% 0% daily.2017-01-06_0010 0B 0% 0%

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.
