If the replicator should be placed into the
OFFLINE
state when replicator stops
or raises an error, the following option can be set through
tpm on the cluster configuration to set the
policy.fence.slaveReplicator
to
true:
shell> tpm update alpha --property=policy.fence.slaveReplicator=true
The delay before the fencing operation takes place can be configured using
the
policy.fence.slaveReplicator.threshold
parameter, which configures the delay before taking action, with the value
multiplied by 10. For example, a setting of 6 implies a delay of 60
seconds. The delay enables transient errors, such as network failures, to
be effectively managed without automatically fencing the Replica.
shell> tpm update alpha --property=policy.fence.slaveReplicator.threshold=6
Once a Replica has been fenced, the state will automatically be cleared when
the replicator returns to the ONLINE
state. Once this has been identified, the node will be placed in the
ONLINE
state.
