[ovirt-users] ovirt and gluster network config

Hi, I have my 5 ovirt nodes up and running and starting to move forward with actual ovirt and gluster setup. I am using gdeploy for deployment. the play book fails saying /dev/sdb is blacklisted by filter? I am following the blog up and running on the ovirt site. It mentioned adding # disable multipath [script2] action=execute file=/usr/share/ansible/gdeploy/scripts/disable-multipath.sh to get it to work, but it does not work. The script 3 section after this does have the file=/usr/share/gdeploy/scripts/blacklist_all_disks.sh in it. What can I do to get past this? Also not sure if I should be modifying the script/play as I don't really want an arbitrator host - if I have 5 real hosts all with the same storage in them? (10TB in each) and it only account for 3 hosts, can I add the other two later or should I try to modify the playbook to include these initially? I am sure I will be setting this up several times before I get it right, but at the moment I can't get past this error. Any help would really be appreciated! Thanks
