<br>
I am currently running a simple gluster setup using one server node<br>
with multiple disks. I realize that if i delete away all the .shard<br>
files in one replica in the backend, my application (dd) will report<br>
Input/Output error even though i have 3 replicas.<br>
<br>
My gluster version is 3.7.16<br>

However, the gfid is not the same compare to the other replicas<br>

Is this consider a bug?<br>
