I want to make the 10 terabytes raid an xfs filesystem and then share the drive with all 4 of the vm's. 3 of the servers will be samba servers and one will be my Lotus notes server. I want to make the filesystem /data and then each one of the servers will use specific sub directories. I have it set up as block devices now but I want the flexibility of having the whole 10 terabytes available to all 4 servers.

Except NFS doesn't follow normal filesystem semantics and you can end up with corrupt data without knowing it, and it, along with CIFS, will give you a free shitload of network overhead to go along with your possibly corrupt data. OCFS2 or GFS are the only practical choices if you want it to behave like a typical filesystem and not have to worry about catering to it or rewriting software and/or reeducating developers, and OCFS2 is extremely easy to set up. The original question didn't specify much about the requirements, though. A single shared filesystem? Read-write or read-only? No filesystem at all? Without that information, I would at first recommend not sharing. It can be a lot of trouble, it's usually not required, and it severely complicates life when things fail. Well, there is always XenFS... :/ --
Though dated, this article is interesting regarding this thread. The article needs to be updated (Last Modified = June 2006), and rewritten for CentOS Xen virtualization, but it looks sound upon my first reading:
