I first encountered this bug about a year ago, and lost more than 100 VM.

Sharding is essential to VM datastores and i think Gluster is't that useful without this feature for VMs.

I appreciate all the hard work that the developers putting on this bug, but i think a warning in CLI or something would be really helpful for Gluster users until the fix is ready.

I absolutely agree - or, just disable the ability to add-brick with
sharding enabled. Losing data should never be allowed.
