I've been attempting to follow the recipe laid-out in the Linbit guide "Highly available iSCSI storage with DRBD and Pacemaker"...

crm configure primitive p_target_iscsivg01 ocf:heartbeat:iSCSITarget params iqn="iqn.2001-04.com.example:storage.example.iscsivg01" tid="1" op monitor interval="10s"
crm configure primitive p_target_iscsivg02 ocf:heartbeat:iSCSITarget params iqn="iqn.2001-04.com.example:storage.example.iscsivg02" tid="2" op monitor interval="10s

crm configure primitive p_iSCSI-san1_0 ocf:heartbeat:iSCSILogicalUnit params target_iqn="iqn.2001-04.com.example:storage.example.iscsivg01" lun="1" path="/dev/iscsivg01/lun1" op monitor interval="10s"
crm configure primitive p_iSCSI-san1_1 ocf:heartbeat:iSCSILogicalUnit params target_iqn="iqn.2001-04.com.example:storage.example.iscsivg01" lun="2" path="/dev/iscsivg0
crm configure primitive p_iSCSI-san1_2 ocf:heartbeat:iSCSILogicalUnit params target_iqn="iqn.2001-04.com.example:storage.example.iscsivg02" lun="1" path="/dev/iscsivg02/lun1" op monitor interval="10s"
crm configure primitive p_iSCSI-san1_3 ocf:heartbeat:iSCSILogicalUnit params target_iqn="iqn.2001-04.com.example:storage.example.iscsivg02" lun="2" path="/dev/iscsivg02/lun2" op monitor interval="10s"
...to create a highly-available iSCSI server on the two servers san1 & san2 but can't quite get the details right:

Code:
crm configure property stonith-enabled=false
crm configure property no-quorum-policy=ignore

crm configure primitive p_IP-1_254 ocf:heartbeat:IPaddr2 params ip=192.168.1.254 cidr_netmask=24 op monitor interval=30s

crm configure primitive p_DRBD-r0 ocf:linbit:drbd params drbd_resource=r0 op monitor interval=60s
crm configure ms ms_DRBD-r0 p_DRBD-r0 meta master-max=1 master-node-max=1 clone-max=2 clone-node-max=1 notify=true

crm configure primitive p_iSCSI-san1 ocf:heartbeat:iSCSITarget params iqn=iqn.2012-11.com.example.san1:sda op monitor interval=10s

crm configure primitive p_iSCSI-san1_3 ocf:heartbeat:iSCSILogicalUnit params target_iqn=iqn.2012-11.com.example.san1:sda lun=3 path=/dev/drbd3 op monitor interval=10s
crm configure primitive p_iSCSI-san1_4 ocf:heartbeat:iSCSILogicalUnit params target_iqn=iqn.2012-11.com.example.san1:sda lun=4 path=/dev/drbd4 op monitor interval=10s

IET (i.e., iscsitarget) is already running (with the default configuration) and DRBD's already correctly configured to create the resource r0...

Code:
resource r0 {
    volume 0 {
        device /dev/drbd0 ;
        disk /dev/sda7 ;
        meta-disk internal ;
    }
    volume 1 {
        device /dev/drbd1 ;
        disk /dev/sda8 ;
        meta-disk internal ;
    }
    volume 2 {
        device /dev/drbd2 ;
        disk /dev/sda9 ;
        meta-disk internal ;
    }
    volume 3 {
        device /dev/drbd3 ;
        disk /dev/sda10 ;
        meta-disk internal ;
    }
    on san1 {
        address 192.168.1.1:7789 ;
    }
    on san2 {
        address 192.168.1.2:7789 ;
    }
}
But the shared IP address won't start nor will the LUN's:
