That just pushes the performance monitoring to other nodes. I am pretty
sure prior to installing the GUI nodes I didn't have any "performance
monitoring" and having never used it would like to get back to that
state of affairs :-)
[root@gpfs0 ~]# mmperfmon config delete --all
mmperfmon: The performance monitoring configuration cannot be deleted
while there are nodes designated for performance monitoring. Please
remove the designation with mmchnode --noperfmon.
mmperfmon: Command failed. Examine previous error messages to determine
cause.
Noting that I have already attempted to designate my one remaining
performance monitoring node (aka GUI node) as not doing that with
mmchnode which does not seem to do anything.
Noting that the manpage for mmperfmon say for config delete --all
removes the entire performance monitoring configuration from
IBM Storage Scale.
I have tried upgrading the GUI node to 5.2.3 to match the rest of the
system, and running the mmchnode --noperfmon on the node itself with
GPFS both started and stopped. None of that made any difference :-( At
least I can run mmchconfig release=LATEST now.
Interestingly mmlscluster shows the two DSS-G nodes as having a
designation of "quorum-manager-perfmon" and the GUI node as having no
designation. Noting the two DSS-G nodes don't have the pmcollector or
pmsensors RPM's installed.
I suspect I am going to need to open a ticket for this one as something
wacky is going on.
