Igor, Thanks for the reply, I am sorry for the delay. Its been a hectic week.
I understand the concept of using RSYNC, an have used it in the past. The intent of this exercise is to teach myself something new, an in this case learning to use DRBD in a environment such as my installation ISO collection, before I start considering my replicated home folder or Movie Collection.

Simply said, Pacemaker controls both DRBD and ISCSI targets and if the slave node detects master's failure - it promotes DRBD to primary, brings up shared ip address and starts ISCSI. But your problem can be, i think, solved much simpler: you just need to rsync your ISO's to another server, because, as i see it, they are changed infrequently. Then you can use cluster manager to fail over IP address between these servers. On 04/12/14 21:44, John Moore (Compucom Systems Inc) wrote: I have researched some about mixing DRBD an ISCSI. An what I am finding is opinions about as vast as what people like on pizza. So I figure I would ask it here... Can I take 2 servers, setup DRBD between them, then configure ISCSI on both servers but only connect to 1 of the ISCSI targets. Leave the other ISCSI service turned off until needed. I would create a VIP between the two servers so that the clients wouldn't need to be reconfigured to point to the new active ISCSI. I am looking for a fail over file system which will hold my ISO an boot images for my PXE environment. DRBD would be configured to listen to a backend network using a small 1gig switch. The ISCSI would be configure to listen on the frontend network connected to the DMZ.
