my environment is:

I added to my admin node 1 new disk with 10GB, i formatted as ext4 and created a lvm mounted in /cloud , in this directory i create a sbd.img using "dd" and shared this .img file using iscsi to my 2 control nodes.
In my two control nodes i enable the softdog module and installed the sbd package using "zypper in sbd" and executed sbd -d /dev/disk/by-path/ip... create, and after sbd -d /dev/disk/by-path/ip... dump , this two commands don't returns any error, but when i try use the "list" option don't return my nodes information.
I tried create the pacemaker cluster using the crowbar interface but returns me the followed error There is no suitable disk for LVM for DRBD
