I frequently change quorum on the fly on both our 4.x and 5.0 clusters during upgrades/maintenance.
You have sanity in the CCR to start with? (mmccr query, lsnodes, etc,etc) Anything useful in the logs or if you drop debug on it?

The RAID card in the server we are currently using is a casualty of the RHEL8 SAS card purge :-( I have a "new" dual core server that is fully supported by RHEL8. After some toing and throwing with IBM they agreed a Pentium G6400 is 70PVU a core and two cores :-) That said it is currently running RHEL7 because that's what the DSS-G nodes are running. The upgrade to RHEL8 is planned for next year. Anyway I have added it into the GPFS cluster all well and good and GPFS is mounted just fine. However when I ran the command to make it a quorum node I got the following error (sanitized to remove actual DNS names and IP addresses initialize (113, '<fqdn-new>', ('<IP address>', 1191)) failed (err 79) server initialization failed (err 79) mmchnode: Unexpected error from chnodes -n 1=<fqdn1>:1191,2<fqdn2>:1191,3=<fqdn3>:1191,113=<fqdn-new>:1191 -f 1 -P 1191 . Return code: 149 mmchnode: Unable to change the CCR quorum node configuration. mmchnode: Command failed. Examine previous error messages to determine cause. fqdn-new is the new node and fqdn1/2/3 are the existing quorum nodes. I want to remove fqdn3 in due course. Anyone any idea what is going on? I thought you could change the quorum nodes on the fly? JAB. -- Jonathan A.
