Field Replication status Fallback baseline Pending data Table 551. SyncRep Field Volume Status Storage pool Reported size SyncRep status SyncAlternate pool Unreplicated data Description Indicates the status of replication activity to or from the partner is enabled or paused Point in time at which the volume on the primary group and the most recent complete replica on the secondary group have the same data Amount of data that must be transferred for the next or current replication 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 locate 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. Displays the SyncRep status for a volume: • in sync - SyncActive and SyncAlternate pools contain the same volume data. • paused - Administrator has paused synchronous replication. While synchronous replication is paused, the volume is still online, and initiators can connect to and write to the SyncActive volume. An administrator can pause and later resume synchronous replication. For example, this situation could happen in a maintenance window during which the SyncAlternate pool is taken offline. If data is written to the volume while synchronous replication is paused, it is written only to the SyncActive pool, and the two pools are out of sync. The group tracks all volume writes while synchronous replication is paused and, when the administrator resumes synchronous replication, writes the tracked changes to the SyncAlternate pool. • out of sync - SyncActive pool and SyncAlternate pool might not contain the same volume data; the SyncActive pool contains the most recent volume data. A volume can become out of sync if synchronous replication is paused, or if one of the pools becomes unavailable or has no free space. The volume can become out of sync when the snapshot reserve in the SyncAlternate pool is full, but only when the snapshot space recovery policy sets volumes offline when the snapshot reserve is depleted. Secondary backup pool for a syncrep volume Amount of data that has not been written to the SyncAlternate pool. Visible when synchronous replication is enabled.
