View Full Version : HA SAN with iSCSI+DRBD

17-Dec-2012, 21:49
I've configured a two-node DRBD cluster with a handful of resources/volumes. Each of the volumes is exported/shared from the DRBD primary node using iscsitarget (iSCSI Enterprise Target - IET). The secondary node is not exported/shared using iSCSI - It's only a duplicate of the primary node.

How can I use Corosync+Pacemaker to make the iSCSI service highly available using the DRBD secondary node?

The LinBit Tech Guide "Highly available iSCSI with DRBD and Pacemaker (http://www.linbit.com/en/downloads/tech-guides?download=9:highly-available-iscsi-with-drbd-and-pacemaker)" seems to address this scenario/use-case perfectly.

I'll report back (here) after I've had time to read it and try out the instructions that it provides. :D

Yes, the tech guide "Highly available iSCSI with DRBD and Pacemaker (http://www.linbit.com/en/downloads/tech-guides?download=9:highly-available-iscsi-with-drbd-and-pacemaker)" is an excellent resource. (See my other post "HA SAN with iSCSI+DRBD (https://forums.suse.com/showthread.php?2271-HA-SAN-with-iSCSI-DRBD)" for more insight into my experience converting Linbit's recipe to suit my needs.)
