[linux-lvm] Shared LUN without CLM

[Руденко Александр]

Hi, friends.

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.

My question.

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)
