It looks like the patch for the mentioned bugzilla is in 4.2.2.0, but not in 4.2.1.2.

Would this patch have made it in to CES/GPFS 4.2.1-2.. from what you say probably not? This whole incident was caused by a scheduled and extremely rare shutdown of our main datacentre for electrical testing. It's not something that's likely to happen again if at all so reproducing it will be nigh on impossible. Food for thought though!

To answer the wider question: Log files are kept in /var/adm/ras/. In case more detailed traces are required, use the mmprotocoltrace command.

Some of the node would just say “failed” or “degraded” with the DCs offline. Of those that thought they were happy to host a CES IP address, they did not respond and winbindd process would take up 100% CPU as seen through top with no users on it. Interesting that even though all CES nodes had the same configuration, three of them never had a problem at all. JF – I’ll look at the protocol tracing next time this happens. It’s a rare thing that three DCs go offline at once but even so there should have been enough resiliency to cope.

Mmfs.log.latest said everything was fine btw.
