Snapshot Details - Snapshot Space Reclaimable

fenton — Thu, 05 Jun 2025 07:04:07 GMT

Is there anyway to get run the Snapshot Space reclaimable feature via CLI or API ?

On the command line there is the 'snap reclaimable' command.

'snap reclaimable volname snapname snapname snapname'

I hope this response has been helpful to you.

At your service,

(P.S. I appreciate points for helpful or correct answers.)

Hi Rich,

We have both CLI and API to do it.

Below is the cli.

[root@lnx ~]# dfpm dataset snapshot reclaimable help

NAME
reclaimable -- compute space reclaimable from deleting snapshots in a volume

SYNOPSIS
dfpm dataset snapshot reclaimable <volume-name-or-id> <snapshot-name-or-id>
[ <snapshot-name-or-id> ... ]

DESCRIPTION
Compute space that can be reclaimed if the specified
set of snapshots are deleted from the given volume.

[root@lnx ~]# dfpm dataset snapshot reclaimable 1615 21050 hourly.2
Approximately 457868KB will be reclaimed by deleting these Snapshot copies.

[root@lnx~]#

PS: Though its a dfpm cli its not necessary that the volume has to be a member of a dataset.

The corresponding is the API.

<snapshot-get-reclaimable-info>

<snapshot-name>21050</snapshot-name>

</snapshot>

<snapshot-name>hourly.2</snapshot-name>

</snapshot>

</snapshots>

<volume-name-or-id>1615</volume-name-or-id>

</snapshot-get-reclaimable-info>
