I'm not sure if one has anything to do with the other, but we're getting
lots of abends on our 5-node cluster. I think it is related to disk usage.
They've run out of disk space on many of the volumes. But there is one
thing that jumped out when I was analyzing the cluster last night.

About a month ago, we removed two nodes from the cluster. 7-node cluster
down to 2-node cluster. Everything was removed properly and according to
documentation. Last night, I realized that in CMON, nodes were showing as
1, 3, 4, 6, and 7. Rather than 1, 2, 3, 4, 5. Obviously, 2 and 5 were the
two nodes removed last month.

My question: does the fact that node numbers haven't been reset indicate
an issue? What should we do at this point?
