Hi,
Currently, we have three UCS C220 M4, dual Xeon CPU (48 cores), 32GB of RAM,
8x900GB spindles, with Intel X520 dual 10G ports. We are planning to migrate
more VMs and increase the number of servers in the cluster as soon as we figure
what's going on with the NFS mount.

I had stability problems with centos 7.2 and gluster 3.7.11. Nodes were crashing without any clue. I cannot find a solution and switched to centos 6.8. All problems gone with 6.8. Maybe you can test with centos 6.8?

How many IOPS are you getting and how much bandwidth when reading/writing? 900GB SAS 15k?
