I want to use shared storage for a XenServer environment with 4 host servers which are running various VMs under XenServer. Planning to use 2 extra servers as storage with high availability of some sort.
While the most obvious solution is iSCSI SAN software, I see some recommendations that one skip iSCSI altogether and go for clustered file systems – most prominent seem GFS2 and Lustre.
However, I don’t see options in XenServer which support connecting to such clustered systems.
First of all, do I need to then make the 4 XenServer hosts also part of the cluster? As I am installing via the Citrix download, I am not familiar how I would go about it, or if I even need to.
Don’t need more than 30 VMs and storage is limited below 4 TB. Under these circumstances, what cluster type is best? Or does this not work at all with Xen?
If you want XenServer to support this you will need to setup your cluster and then "reshare" a nfs or iscsi mount point for XenServer to use. Since it sounds like your 4 servers are tied up running XenServer I don't think a cluster makes a lot of sense for you

I never saw support for them from Citrix in official manuals. If I were you, I would go iSCSI. It's stable enough and good support.
