Good.   You don't want the system to auto-connect the iSCSI disks on
boot, pacemaker will do that for you.

The resources are listed in top-down start order.  So you're starting
ClusterIP, but then try to start the filesystem when you still haven't
connected to the iSCSI disk or started the volume group.

You have conflicting orders, there.  A resource group defines an
order, so the other order statement seems unnecessary.  If you remove
that order constraint, and change your group line so that things start
in the correct order, does it come up?

group CL_group ClusterIP ISCSI_disk VG_disk FS_disk PM_ping

I left off IP_ping, because it's exactly the same as ClusterIP.  Was
it meant to be something else?
