From the description, I am assuming your cluster has 3 quorum nodes. One of the quorum nodes is down. To maintain node quorum, you should only add a non-quorum node to the cluster. Start gpfs on that node, then use mmchnode command to change that node to quorum node. Another option is to remove the quorum role on the failed node first, then add 1 quorum node.

We have - it seems - just lost one of our NSDs.The other took over as it should - but unfortunately, the protocol nodes (i.e. I have a number of nodes which now have stale file handles. (The file system is accessible on the remaining NSD server and a number of other clients.) Unfortunately, in the 'home' cluster - the one that ones the disks - I only have, five servers; three of which are quorum nodes, and of course the failed NSD server is one of them. The question is - can I add quorum nodes with one node down, and can I remove quorum functionality from a failed node?
