Taking windows role default settings - (n-1) failovers ok within 6 hrs , where n=# of nodes, if nodes = 2, 1 failover within 6 hrs is allowed.
Taking resource default settings - Within 15mins period, 1 restart is allowed on the same node, else failover, RetryPeriodOnFailure is 1 hr
Taking a example of a simple 2 node cluster (node1 & Node2), single sqlFCI (sql), say sql is on node 1 at 9AM.
9AM - sql fails - attempts to restart on Node1 - fails - failsover to Node2 - attempts to restart on Node2 - fails - stays failed.
Now where I am confused is, https://support.microsoft.com/en-us/help/947712/failover-cluster-resource-recovery-behavior-in-windows-server-2008, "If there is no intervention and the resource remains in the failed state for 60 minutes, Windows Server tries to bring the resource online again."
So, according to above, after 60mins, say sometime after 10AM - Does sql try a cycle again :
Attempts sql restart on Node2 - fails - (but cannot failover as 6hrs have not passed)
11AM- Attempts sql restart on Node2 - fails - (but cannot failover as 6hrs have not passed)
12PM - Attempts sql restart on Node2 - fails - (but cannot failover as 6hrs have not passed)
1PM - Attempts sql restart on Node2 - fails - (but cannot failover as 6hrs have not passed)
2PM - Attempts sql restart on Node2 - fails - (but cannot failover as 6hrs have not passed)
3PM - Attempts sql restart on Node2 - fails - failsover to node1 as 6 hrs have passed, tries coming online there , and so on.. is this how it happens? Thanks.
