Are you sure you use the right device in your fstab? If yes, could you 
please strace the mount process to see the arguments mount.ocfs2 give to 
ocfs2_hb_ctl and why it fails?

So here you mean you can mount an old ocfs2 filesystem in your single 
node, right? If yes, have you updated the ocfs2-tools recently(If you 
use a new mkfs.ocfs2(like 1.3.9) and an old ocfs2_hb_ctl(like 1.2.x), it 
will fails).

btw, is there any error message in dmesg?
