Yes, forgot to mention those are freshly built Centos 6.5 systems with zfs 0.6.2, and glusterfs-3.4.1-3.el6.x86_64, vdsm-gluster-4.13.2-1.el6.noarch for testing/experimenting. Bought some cheap SSDs and just grabbed systems and platters I had around for it. Testbedding and getting some experience with the self hosted engine, since I’d like to move to it once it’s released. Also looking forward to testing native gluster on this setup.

I have a production ovirt cluster with a linux zfs based NFS storage server, the backend has been very stable since I got rid of Nextenta and went to linux. Sounds odd, I know, but couldn’t get good support for a community nextenta server I inherited. I was having driver level box lockup issues with openSolaris that I couldn’t resolve. So I rebuilt it with linux, imported the pool, and haven’t looked back or had a storage failure since.
