Ok, thanks, I thought about this option too and it seems it works.
More testing in place.
In this cluster I have many services and each one is bundled with its
own VGs, so that each node is active for that particular service.
To use CLVMD is comfortable when I need to add LUNs or resize pre-existing ones.
I had a doubt if running "vgchange -cn" when both nodes are online
could cause any problem so I was not sure...
What does it happen with node 2 when I run this command on node 1?
"SImply" that node cannot online the VG any more or worse it can
online it without safety and cause data corruption?
What the best behaviour to avoid data corruption for the few seconds I
need to make a snapshot of a not-clustered VG?
