glusterd: Add multiple checks before attach/start a brick
Problem: In brick mux scenario sometime glusterd is not able
to start/attach a brick and gluster v status shows
brick is already running
Solution:
1) To make sure brick is running check brick_path in
/proc/<pid>/fd , if a brick is consumed by the brick
process it means brick stack is come up otherwise not
2) Before start/attach a brick check if a brick is mounted
or not
3) At the time of printing volume status check brick is
consumed by any brick process
Test: To test the same followed procedure
1) Setup brick mux environment on a vm
2) Put a breaking point in gdb in function posix_health_check_thread_proc
at the time of notify GF_EVENT_CHILD_DOWN event
3) unmount anyone brick path forcefully
4) check gluster v status it will show N/A for the brick
5) Try to start volume with force option, glusterd throw
message "No device available for mount brick"
6) Mount the brick_root path
7) Try to start volume with force option
8) down brick is started successfully
