How again to make VG cluster aware while no cluster services are running

[Ralph Grothe]

Hello Forumers,

I used to know that once but cannot remember anymore, how to overcome the chicken and egg dilemma where there are no cluster services running when during cluster configuration a cluster aware VG must be marked as such
(i.e. vgchange -c y ...).
I'm even failing to find such an entry in the Knowledge Base, probably due to my misfit key words.

Regards
Ralph

Sorry for bothering you.

I found out myself.
This was a hiddeous little devil.

All that was needed to explicitly run

vgchange -a n /dev/vg_to_be_shared

vgchange -S n -c n /dev/vg_to_be_shared

on *every* cluster node *prior* to cmapplyconf.

Then the cmapplyconf -C my_rotten_conf
worked.

Great.
If it works then it's not rotten. :)

Something to note....
cmapplyconf will install the cluster ID on a VOLUME_GROUP whether or not the cluster is running.

If a VOLUME_GROUP reference is removed from the cluster configuration file, cmapplyconf will remove the cluster ID from the VG, whether or not the cluster is running.
