Lindsay,
I wanted to ask you one more thing: specifically in VM workload with sharding, do you run into consistency issues with strict-write-ordering being off?
I remember suggesting that this option be enabled. But that was for plain dd on the mountpoint (and not inside the vm), where it was necessary.
I want to know if it is *really* necessary in VM workloads.

When disabled I can freely migrate VM's, emabled, things rapidly go pear shaped.
