Hi Brian,

which version were you using before 3.7.1? Did that problem occur with 
version 3.7.1 meanwhile?

Once that happens, heal doesn't work often and while it is in such a state, the VM often becomes unresponsive. I've had to pick on of the qcow files from a brick, copy it somewhere, delete the file from gluster and then copy the file from a brick to gluster.
