'Glusterd' stops immediately on restart, 'df -h' shows "Transport endpoint is not connected", why?

Issue

• Glusterd stops immediately after restarting.

# service glusterd start
Starting glusterd:                                         [  OK  ]
# service glusterd status
glusterd (pid  24291) is running...
# service glusterd status
glusterd is stopped

• 'df -h' shows the message "Transport endpoint is not connected".
