Hi Joseph, yes, that's what i thought. But why doesn't the other node have the same proplem ? Also on the other host the port is opened as the last step during boot, after starting the ocfs2 and the o2cb init script. But it suceeded in mounting the volume !?!
Then this would be a design error from Suse.
