Snapshots of GPFS file systems or filesets

View the information that is shown about snapshots in file storage systems.

A snapshot is a copy of the changed data in the active files and directories of a GPFS file system or fileset. By default, IBM Storage Insights Pro does not collect information about the size of GPFS snapshots. To enable IBM Storage Insights Pro to collect that information, open a case with IBM® Support.

Important: Collecting size information about GPFS snapshots might put a significant load on the IBM Storage Scale System cluster, and might affect other applications that use the same cluster.

The snapshot can consist of a snapshot of the file system or a fileset in the file system. If the snapshot is a snapshot of a fileset, the name of the file system and the name of the fileset is shown. Otherwise, only the name of the file system is shown.

Valid: The status of the snapshot. A value of Yes indicates that the snapshot is valid. A value of No indicates that the snapshot is invalid. The snapshot might be invalid because, for example, it is being deleted. Use the status to determine the condition of a snapshot, and if any actions must be taken.
