Storage Issues on Proxmox 4

I am running into a very odd issue with a new iSCSI storage solution we purchased. I will do my best to describe the issue I am seeing as it is a very odd one.

Storage Hardware
Nimble CS300 iSCSI 10G

Servers
HP DL 380 Gen9

I currently have two hosts configured and connected to the Nimble CS300. One of the hosts is a updated Proxmox 3.4 install and the other is a updated Proxmox 4 install.

If I setup a fresh VM on the Proxmox 4 node and try to install any OS it will fail due to not being able to create the filesystem properly. It looks as if its an issue with creating the journal.

I was originally thinking this was a issue with the storage, but after testing with Proxmox 3.4 I don't feel that is the case.

I can move the VM config over to the proxmox 3.4 host, and boom it installs with no issues. This leads me to believe that this is an issue with proxmox 4, but im very stumped as to what the issue could be.

OS Install's I have tried, all of them have the same issues. Move over to the Proxmox 3.4 host and the install no problem.
CentOS6
CentOS7
Ubuntu
Windows 7

Providing some SS of a CentOS6 install when it fails.
