Hi there,
We have a cluster that has 4 nodes with Ceph storage. One of those nodes died yesterday, which puts the cluster in danger of freezing if another node goes down. I'm working on getting the dead node repaired and back online, but it will take a few weeks to get parts for it and get it fixed and running again.
In the meantime, could I add a server that does NOT have any storage on it just to keep the cluster going in case another node goes down? I have a couple of servers that are loaded in RAM and CPU but do not have any storage. If I could add one of those in there just to be able to run VM's, would that work?
And how would I go about adding that node to the cluster?
