Listing snapshots

Use the mmlssnapshot command to display existing snapshots of a file system and their attributes.

The -d option displays the amount of storage used by a snapshot. GPFS quota management does not take the data blocks used to store snapshots into account when reporting on and determining if quota limits have been exceeded. This is a slow operation and its usage is suggested for problem determination only.

For example, to display the snapshot information for the file system fs1 with additional storage information, issue the following command:

mmlssnapshot fs1 -d

The system displays information similar to:

Snapshots in file system fs1: [data and metadata in KB]
Directory                SnapId    Status          Created                        Data  Metadata
snap1                    1         Valid           Fri Oct 17 10:56:22 2003          0       512

For complete usage information, see mmlssnapshot command.
