Oh, and I forgot to add that when I try to create the LUN with the
implementation=”lio” parameter, I see the following:
[root@hdc1anas002 ec2-user]# pcs resource create hdcvbnas_lun0
ocf:heartbeat:iSCSILogicalUnit
target_iqn="iqn.2016-07.local.hsinawsdev:hdcvadbs-witness" lun="0"
path=/dev/drbd1 implementation="lio" op monitor interval=15s

Subject: [ClusterLabs] HA iSCSITarget Using FileIO
I’m having some difficulty setting up a PCS/Corosync HA iSCSI target. I’m able
to create the iSCSI target resource (it spins up the target service properly
when the pcs command is issued. However, when I attempt to create a LUN, I get
nothing but error messages. This works:
pcs resource create hdcvbnas_tgtsvc ocf:heartbeat:iSCSITarget
iqn=”iqn.2016-07.local.hsinawsdev:hdcvadbs-witness” op monitor interval=15s
But this does not:
pcs resource create hdcvbnas_tgtsvc ocf:heartbeat:iSCSITarget
iqn=”iqn.2016-07.local.hsinawsdev:hdcvadbs-witness” implementation=”lio”
portals=”10.0.96.100 10.0.96.101” op monitor interval=15s
Also, when the first (working) command is issued, the creation of the LUN does
not:
pcs resource create hdcvbnas_lun0 ocf:heartbeat:iSCSILogicalUnit
target_iqn=”iqn.2016-07.local.hsinawsdev:hdcvadbs-witness” lun=”0”
path=/dev/drbd1 op monitor interval=15s
Here’s the results:

Unfortunately, neither the corosync nor syslog logs provide any information
that is remotely helpful in troubleshooting this. I appreciate any help you
might provide.
