Hi, are the nodes running on AIX? If so my advice would be to change /var/mmfs/mmsysmon/mmsysmonitor.conf to read [InterNodeEventing] usesharedlib = 0 and the do a "mmsysmoncontrol restart". What was the min. release level before the upgrade? For most other cases a "mmsysmoncontrol restart" on the affected nodes + cluster manager node should do.

This can be easily cleared with "mmhealth node show --resync", however after some minutes the error re-appears. Apparently, no errors in the log files and no apparent problems other than the "csm_resync_needed" error. Before opening a support case, any hints about what could be the reason of that and whether I should worry about it? I would like to clarify what's going on before upgrading the main cluster.
