I assume your VMs use gluster as the storage. In that case, the
gluster volume might be mounted on all the hypervisors.
The mount/ client is smart enough to give the correct data from the
other two machines which were always up.
This is the reason things are working fine.

Gluster should heal the brick.
Adding people how can help you better with the heal part.
@Karthik Subrahmanya  @Ravishankar N do take a look and answer this part.
