[Ocfs2-users] Query regarding OCFS2 and RHEL4 LVM

[Pedro Figueira]

Hi all

Why do you consider the LVM2 not cluster safe? Is it just because you should not (can't) modify any LVM configuration with the volume groups activated in more than one server?

thanks

	It is possible if done carefully, but it is not cluster safe and
not recommeneded for a production environment.
