I am planning to use redhat cluster, gfs, drbd to create a highly available iscsi storage server.
will they work? any online documentation available?
pls kindly advise.

I'm trying to set up two machines synchonizing with DRBD. The storage is setup as follows: PV -> LVM -> DRBD -> CLVM -> GFS2.
DRBD is set up in dual primary mode. The first server is set up and running fine in primary mode. The drives on the first server have data on them. I've set up the second server and I'm trying to bring up the DRBD resources.
Does anyone know if KVM has a method to control IO per virtual machine? I am looking for a way to better control the "Noisy Neighbor" VM's. I am running Ubuntu KVM to a Ubuntu DRBD cluster for storage. The root issue is at time a VM will request significant IO bringing the other VM's on the Storage to a crawl.
We have a cluster with multiple ubuntu machines which are connected to a shared SAN storage. Initially we were using OCFS2 as file system but we were hit with so many issues and we couldn't find proper documentation or support therefore we have decided to move to another cluster system.
This question is a follow-on from Dedicated NIC or dedicated port for iSCSI?
Excluding the hardware iSCSI initiator point that was made in the accepted answer to the above question, it seems that using separate port(s) on a multi-port NIC for iSCSI is pretty much going to meet the recommendation of using "seperate NICs" for iSCSI traffic.
I'm in the process of planning a small iSCSI installation
