Our Highly Available iSCSI Solution using SCST, Pacemaker and Corosync

For this weeks video, Mitch dives into the comparison between both default iSCSI solutions for #Linux and #Ceph (including a deep dive into iSCSI terminology). After looking at the advantages and disadvantages of each, 45Drives decided to build our own highly available iSCSI solution using the combination of SCST, Pacemaker and Corosync.
Check out this week's video for a live failover demo showing this solution in action.

FINALLY! I have always been missing the iscsi part for all other "webui" solutions except truenas, and now you´re making it a part of houston AND with clustering so i will definitively migrate my stuff over to houston. THANK YOU FOR DOING THIS!

Great video. It would be cool to see how a Windows Server VM on ESXi with its drives on a VMDK handles an iSCSI failover, especially in that longer worst case wait period. Looking forward to seeing this in Houston.

I would like to see this with VMs running on the iSCSI device. Do they crash? Corrupted?

Is it feasible to deploy two Dell servers, each installed with the requisite 45 software, interconnected via a 10GB cable to establish a high-availability (HA) setup? In this configuration, if Host A experiences a failure, Host B would seamlessly take over, thereby ensuring iSCSI HA functionality.
