Sorry, I don't have experience with gluster. I see it used here and there but don't have experience about its performance. I guess you can benchmark it in your specific environment. I had bad experience in the past of trying to run database or any more demanding workloads on NFS. It is only personal experience though. If you are running on some public cloud provider usually PVs can be created as volumes/disks on that cloud. Or cinder volumes in OpenStack. See supported block storage types [1]. I read discouragements about NFS there as well. I think netapp and other storage vendors provide OpenStack storage management technology so maybe it is a viable option to check with them as a storage backend, just not over NFS. Maybe plain iSCSI volumes will do the trick with any storage vendor.
