The ceph.sh script is called by the mtcClient process during the
system start-up. This script will then start the Ceph processes.
The mtcClient uses the UDP port 2119 to communicate with other hosts,
and these Ceph processes inherit the UDP port from the mtcClient
because the file descriptor is kept open when forking the application.
When the mtcClient process restarts, the Ceph processes with the
inherited file descriptor will automatically start using that UDP
port, blocking the mtcClient from binding to that port.
The solution is to call the ceph-init-wrapper script using the
"systemd-run" command as a transient service with "--pipe" and
"--wait" to isolate all the FDs except for the stdin/stdout/stderr.
Test-Plan:
PASS: Multi-node system - Unmanage and stop all Ceph processes on
controller-0, and kill the mtcClient process twice. Check if
only mtcClient is listed using UDP port 2119 by running
'sudo lsof -iUDP:2119'.
PASS: Deploy AIO-SX and check if Ceph status is HEALTH_OK. The
mtcClient will not bind UDP 2119 port in this configuration.
PASS: Deploy AIO-DX and check if only mtcClient is listed using
UDP port 2119 by running 'sudo lsof -iUDP:2119'.
