[Ocfs2-users] Problem with clustering on Linux

[Marcos E. Matsunaga]

George,

You clearly have two different volumes (UUID are different), one on each
machine.

Make sure you have a shared disk that can be accessed by both systems.
You have to format the partition only in one of the systems and
mounted.ocfs2 -d should show it on both systems (same UUID).

Your problem seems to be more of a hardware configuration than ocfs2.
