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.
