The value of the volume reserve depends on whether you enable thin provisioning on a volume: • If thin provisioning is disabled, volume reserve is equal to the reported size. • If thin provisioning is enabled, volume reserve is equal to or less than the reported size, depending on volume usage and the thin-provisioning settings. Unused space on the volume Amount of space, based on a percentage of the volume reserve, that the group allocates to snapshots Amount of space available for snapshots Amount of space borrowed from the free pool space Description Name of the volume Indicates whether a volume is online or offline. An iSCSI initiator can only discover or connect to an online volume. Storage pool where the volume is located Reported size of the volume in MB, GB, or TB. The group rounds up volume sizes to the next 15MB if the size is not a multiple of 15MB. You cannot change the reported size of a template volume. Name of the replication partner group Amount of space on the secondary group delegated for partner replicas Amount of space delegated to local replication reserve. Local replication reserve has the following purpose: • Preserves the contents of the volume at the time replication started. The primary group creates a snapshot of the volume in the local replication reserve to preserve the contents of the volume at the time replication started. If the volume changes occur during replication, the snapshot tracks those changes, consuming more local replication reserve. 582 Reference: GUI Panels, Wizards, and Dialog Boxes
