On a shared FC resource it works just fine. I just figured out that it runs 
when I'm using iscsi-target http://sourceforge.net/projects/iscsitarget/ 
whereas with scsi-tgt (provided by Redhat) or with NetApp ISCSI 
Implementation it does not (after the first node joins the fence_domain it 
stucks in JOIN_START_WAIT).

I don't think that the cluster.conf helps very much because it works when I 
change the iscsi implementation everything works just fine.
The relevant part is as follows:

  <cman expected_votes="3" two_node="0"/>
  <fence_daemon post_fail_delay="0" post_join_delay="3" clean_start="1"/>
  <quorumd interval="3" tko="9" votes="1" label="qdiskl"/>
  <totem token="54000"/>

I was wandering if the qdisk requires special scsi functionality which I doubt 
but wanted to be sure. Or anybody else experianced a strange behaviour when 
using qdisk on iSCSI.

Lon, perhaps you could just comment on this shortly.
