quorum heartbeat retires specifies the number of times an instance retries a failed quorum heartbeat before exiting. A value of 2 indicates that an instance terminates after the third consecutive quorum heartbeat failure. Tuning quorum heartbeat retires to a low number causes a faster failover when access to the quorum device is lost on a given instance, possibly improving an application’s recovery time as the risk of failing an instance due to a transient condition is reduced. Setting this parameter to a high number degrades application recovery after an instance loses access to the shared disks, reducing the chances that a transient disk access problem can cause an instance failure.
Setting quorum heartbeat interval to
the default (5) and quorum heartbeat retries to
its default (2) implies the time from disk failure detection to
instance shutdown is between 10 and 15 seconds, consisting of 0
to 5 seconds for the first heartbeat failure and 5 seconds for each
of two retries.
