Resizing Snapshot Space
If you constantly get snapshot invalidation alerts, consider either increasing the frequency of
the snapshot or increasing the reserved snapshot space. To do this, or to eliminate your
existing snapshot space (thus increasing your usable volume space), you can specify the
snapshot space you want in the Snapshot Space section. Simply select a value from the
pull-down menu and click Save. Your snapshot space will be limited to the specified
percentage of your volume capacity.
Resizing the snapshot space occurs offline and can take a while depending on the data
volume size, and the number of files in the volume. Expanding the snapshot space reduces
the data volume size. Reducing the snapshot space expands the volume size.
Because of the way snapshots work, you must encounter a drop in write performance when a
snapshot is active. If your environment requires the highest performance throughput, the
active snapshot should be deleted. Alternatively, set a limit on how long the snapshot should
be live.
