8.1.4.2 Checking the Status of Replication
Primary: The node of source volume. All the writing and reading are done on the
primary node.
Secondary: The node of destination volume. The replicated data on the secondary
node is used for backup only and is not accessible. Only the source data is
accessible during replication.
Unknown: The node fails to establish connection.
UpToDate: The node is updated.
Setting the replicated volume on destination proNAS to be Primary
To set the replicated volume to primary, first you need to set both nodes to
secondary. This can be done by setting the primary to be secondary. After both
nodes becomes secondary/secondary, go to the management GUI of the
destination node. Under the replicated logical volume, press the "Set Primary"
button.
WARNING! The replicated volume on the secondary node must not
be mounted. Please do not attempt to mount it manually.
Setting the primary volume to be secondary
To set the primary volume to be secondary, just press the "Set Secondary"
button on the primary node.
Forcing the synchronization
To manually force the synchronization, press the "Force Sync." button. The data
on the primary node will be forcefully synchronized to the secondary node.
Reconnect when the connection of the peer is lost.
To reconnect the replicated volume, press the "Reconnect" button. At some point
if the replication fails to establish connection to the other node, you may try to
set up a connection thru this button. This button will be enabled only if one of the
node losses connection.
Aborting the replication
To abort or drop the replication, press the "Abort Replication" button. To access
the data on the replicated volume after aborting the replication, you may need to
create a share under destination volume whose share name must be equal to the
share name on the source proNAS.
