Failover Cluster Recovery Steps

Question

Hi there,

I recently had a power failure that took out my home lab which has 3x Hyper-V servers that are poart of a Failover Cluster with one external File Share Witness

Due to my DCs being virtualised and, I was unable to start the cluster normally as all the NICs were using either the Public or Private firewall profiles.

I now have 2 nodes backup and running (1 server is currently down due to a PSU failure) and I've got the FSW back online

So just looking for confirmation that my cluster is back to normal. I've reset the node weight to 0 and can see that the 2 active nodes both have a "vote".

So really I just want to know if there anything else that I need to do to ensure the cluster is now healthy and that I can pause nodes and reboot them (one at a time) without knocking it all offline

Answer 1

I would run a cluster health validation there are some items there that will show up as false positives sometimes but it would be the best starting point
