I have a two node cluster that I am trying to add a 3rd node to. When I looked at the partitions in nssmu, I noticed that there are two designated as Cluster partitions and each are 8MB in size. When I try to add the third node, it gets confused and wont join the cluster. So, my questions are these: How do I find out which SBD partition the existing cluster is using? Is it ok to delete the partition that is not being used? Will this affect the cluster?
