We fixed this (thanks to Satheesaran for recreating the issue and to
Raghavendra G and Pranith for the RCA) as recently as last week.
The bug was in DHT-shard interaction.

The patches are https://review.gluster.org/#/c/16709/ followed by
https://review.gluster.org/#/c/14419 to be applied in that order.

Do you mind giving these a try before it makes it into the next .x releases
of 3.8, 3.9 and 3.10?
I could make the src tarball with these patches applied if you like.

> Hi,
> We have a volume of 4 servers 8x2 bricks (Distributed-Replicate) hosting
> VMs for ESXi, i tried expanding the volume with 8 more bricks, and after
> rebalancing the volume, the VMs got corrupted.
> Gluster version is 3.8.9 and the volume is using the default parameters of
> group "virt" plus sharding.
> I created a new volume without sharding and got the same issue after the
> rebalance.
> I checked the reported bugs and the mailing list, and i noticed it's a bug
> in Gluster.
> Is it affecting all of Gluster versions ? is there any workaround or a
> volume setup that is not affected by this issue ?
> Thank you.
