[gpfsug-discuss] "csm_resync_needed" after upgrading to GPFS v5.0.4-2

[Norbert Schuld]

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.

Mit freundlichen Grüßen / Kind regards

Norbert Schuld

Hi all,

after upgrading one of the clusters to GPFS v5.0.4-2 and setting
"minReleaseLevel 5.0.4.0" I started to see random "csm_resync_needed"
errors on some nodes. 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.

Thanks a lot,
Marc
