Thanks. I hadn't seen the command line upgrade instructions. I agree it's a good idea. In our case, it took nearly 4 hours to get the block report, so I wanted to make sure there was some value in having it.

The upgrade instructions call for running a block report to be used later in the process but the docs never mention it again. Why do we run a block report? I know I have no corrupt blocks.

What are the recommended mount options for xfs?

I have a cluster with over 300 nodes. We have HA NN and three JN. I've always had the NN and JN on different hosts but recently got a suggestion to co-locate them, or at least co-locate two JN with NN, and the other JN on an unrelated host. I have co-located them in small clusters in the past, and in our dev environment they are co-located. What's the best practice?
