Snapshot reserve

The snapshot reserve enables you to set aside a minimum percentage of the cluster storage capacity specifically for snapshots. If specified, all other OneFS operations are unable to access the percentage of cluster capacity that is reserved for snapshots.

The snapshot reserve does not limit the amount of space that snapshots can consume on the cluster. Snapshots can consume a greater percentage of storage capacity specified by the snapshot reserve. It is recommended that you do not specify a snapshot reserve.
