It looks that your disk heartbeat is still there. I don't know the 
specific reason, maybe 
http://oss.oracle.com/bugzilla/show_bug.cgi?id=1053 ?

but you can stop it manually.
1.  ocfs2_hb_ctl -I -d <device>
or ocfs2_hb_ctl -I -u <uuid>
this will tell you the reference number for the hearbeat.
2.  ocfs2_hb_ctl -K -d <device> <service>
   or  ocfs2_hb_ctl -K -u <uuid> <service>
this will killed the heartbeat manually.
service is the stack you used, and it should be "o2cb" in your case.

btw, you can try cfs2_hb_ctl -K -u <uuid> <service> to see whether it is 
the same problem as bug 1053.
