Hi Sergio, thanks for an answer. Can I ask you for more explanation, please? Does it mean that if I want to mount ocfs2/drbd partitions concurrently I must use OCFS2 drivers compiled with the same version kernel on all nodes? And on the other hand - if I'd umount this partitions on non-upgraded node would I be able to mount them on upgraded one? Or need I remove drivers as well? I can't stop virtual guests and play with running node to try it but I can plan and announce short break for some night if it would be the way. Thanks in advance Tomas Lavicky
