Description
If osd.5 is already up and running, following command will try to start osd.5 again.
/usr/bin/ceph-osd -i 5 --pid-file /var/run/ceph/osd.5.pid
this command fails, but the pid file for osd.5 is removed [1] after the command returns.
so we can not identify the running osd.5 using the pid file any more, hence not able to kill it using its pid.
as a result, test/erasure-code/test-erasure-code.sh will leave us with some running OSD daemons after it returns, even if this test passes.

[1] ceph-osd use pidfile_write(g_conf) to write pid file, use atexit(pidfile_remove_void) to remove the pid file.
