glusterfs: Not able to mount running volume after enable brick mux and stopped any volume
Problem: After enabled brick mux if any volume has down and then try ot run mount
with running volume , mount command is hung.
Solution: After enable brick mux server has shared one data structure server_conf
for all associated subvolumes.After down any subvolume in some
ungraceful manner (remove brick directory) posix xlator sends
GF_EVENT_CHILD_DOWN event to parent xlatros and server notify
updates the child_up to false in server_conf.When client is trying
to communicate with server through mount it checks conf->child_up
and it is FALSE so it throws message "translator are not yet ready".
From this patch updated structure server_conf to save child_up status
for xlator wise. Another improtant correction from this patch is
cleanup threads from server side xlators after stop the volume.
BUG: 1453977
