I have strange question)
I have one shared LUN on many different hosts.
LUN is PV in some VG.
Each hosts can make any operation in this VG - create LV, remove LV, resize LV, etc.
If i want access to same LV on same host, i take "lvscan" and "lvchange -aey /dev/VG/LV_name".
I'm sure can't two modification VG in same time.
It work fine for me.
Can i not use the CLVM extension?
CLVM is great extension for LVM, but i will have more 100 nodes.
This count not supported in corosync.
Sorry for my english)
