Saw some people asking for profile info. So I had started a migration from a 6TB WDGold 2+1arb replicated gluster to a 1TB samsung ssd 2+1 rep gluster and it's been running a while for a 100GB file thin provisioned with like 28GB actually used. Here is the profile info. I started the

I expect VM's to be able to write at 200MB or 500MB to the hdd/ssd when using an NFS mount or gluster from inside a VM. But heck, it's not even 10% (20MB or 50MB), it's closer to 2.5%-5% of the speed of the drives. I expect windows services to not timeout due to slow hard drives while booting.
