I noticed iSCSILogicalUnit resource agent having faulty behavior with CentOS 5.4 that causes it to fail in monitor operation. 


Every monitor cycle it executes the following command:

   tgtadm --lld iscsi --op show --mode target

and tries to figure out if there is the volume we're looking for with grep and throwing a success accordingly:

   grep -E -q "[[:space:]]+Backing store: ${OCF_RESKEY_path}" && return $OCF_SUCCESS


In CentOS 5.4 that regexp never matches because there is no such string. Instead there is a string "Backing store path:" with the volume information. Therefore it should be safe enough to modify the previous into:

   grep -E -q "[[:space:]]+Backing store.+: ${OCF_RESKEY_path}" && return $OCF_SUCCESS

resulting in succesful operation with CentOS 5.4. Attached the modified and tested iSCSILogicalUnit resource agent.
