[Pacemaker] Shared storage

[Riccardo Bicelli]

Hello everybody and excuse me in advance for the apparently dumb 
question, but I havent found any answer yet!

I'd want to create a gfs2 filesystem.
for doing this I attached to my nodes a shared SCSI lun (shared disk in 
vmware).

For commodity I have created a LVM volume group on it and a volume.

Now, I'd want to create a GFS filesystem on top of the LVM volume.

My question is, do I need to setup CLVM for using GFS2 on top of this setup?

Many thanks.
Riccardo
