When glusterd restarts bricks processes are brought up asynchronously
and hence you may not see the brick processes reflecting in gluster
volume status output immediately after restart. 5-10 seconds is an
accepted time frame. However if it doesn't come back online post that
then probably brick fails to start in that case.

Please check the respective brick log file and if you can find any error
logs in it.
