[ovirt-users] GFS2 and OCFS2 for Shared Storage

[Fernando Frediani]

Are you sure Pavel ?

As far as I know and it has been discussed in this list before, the 
limitation is in CLVM which doesn't support Thinprovisioning yet. LVM2 
does, but it is not in Clustered mode. I tried to use GFS2 in the past 
for other non-virtualization related stuff and didn't have much success 
either.

What about OCFS2 ? Has anyone ?
