In general, these two settings do not need to be changed.
MNSFileShareCheckInterval is the time interval the cluster uses to verify the health of the file share
witness. The default value is 4 minutes (240 seconds), and can be set from 4 seconds to 268,435,455
seconds.
MNSFileShareDelay is the delay in seconds that the cluster node (which does not currently own the file
share witness) will wait until it tries to get the vote from the witness. This allows the current owner of
the file share witness resource to be preferred when trying to win the vote.
The other two parameters configure the heartbeat. The cluster heartbeat is periodic communications sent
between the nodes to confirm the node ??™ s network interface is still active. The goal is to minimize
unnecessary failovers if a few packets get delayed or dropped. The default configuration sends a
heartbeat message every 1.2 seconds from each node. It is not possible to change the timing of the
heartbeat message; rather it is possible to configure the number of heartbeats needed to report interface
or node failure with the parameters HeartBeatLostInterfaceTicks and HeartBeatLostNodeTicks .
HeartBeatLostInterfaceTicks is 3 missed heartbeats by default and can be configured from 2 to 20 .
The default for HeartBeatLostNodeTicks is 6 and can be anywhere from 2 to 20 .
