Details:

When testing I killed the glusterfsd process (and it also occured after a
reboot of the server) a few moments after, read/write operations to the
mountpoint started failing with 'Transport endpoint is not connected'

after the node was restarted the system may recover, however this does not
always happen.

The docs say afr is RAID1, normally RAID1 will continue to operate when a
drive is lost.
