- Snapshot size changes after creation.
Snapshot space usage can be checked by running the following commands:
The snap reclaimable command calculates the volume space that would be reclaimed if one or more specified Snapshots are deleted.
Note: This can be a long-running task as it is CPU intensive.
node> snap reclaimable vol_name snapshot_name
Snap delta displays the rate of change between snapshots.
node> snap delta vol_name
Snap list displays a single line of information for each snapshot.
Along with the snapshot’s name, it shows when the snapshot was created and the size of the snapshot.
node> snap list vol_name
For snap command options, refer to the manual page.
