The quorum disk is a witness disk with hold extra copy of clus DB. This help the cluster availabbility. Normally this disk is not used for other purpose. It doesn't mean the other disks will be offline /failed if if the quorum disk is failed. What/how many disks is in your cluster?

None of the MS documentation makes this clear to me. If I have a two-node sql cluster and it's set as node&disk, then if the disk goes offline, the cluster stays up because the nodes are still running? how is this supposed to work? if the disk is offline then most likely your data drive is too, in which case sql isn't going to run well. came somebody clear this up for me?

You can only configure 1 FSW per Cluster.

Please look at the 'Node & File Share Majority' above to understand how the Quorum Votes are calculated.

If you have your Cluster nodes up and running and you loose connectivity to File Share Witness (3rd site) then the cluster would continue to run provided you have enough number of Cluster Nodes up and running.

Thanks,

Hi Can i configure 2 FSWs in a cluster (from 3rd and 4th location). This is not to increase the votes but just to have high availability at share level. if the connection to the site3 lost site4 FSW provide a vote and if the connection to the site4 lost site3 FSW will provide the vote.

Hi, I would like to know how to migrate the Quorum disk? Meanwhile, downtime is essential for migration?
