[Gluster-users] File Corruption with shards - 100% reproducable

[Krutika Dhananjay]

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.
