Hi all,

         I started ceph through /etc/init.d/ -a start,but it was not stop.I tried 
with /etc/init.d/ceph -a stop and /etc/init.d/ceph -v -a stop and 
service ceph -a stop also,there is no error logs showing.I tried with 
/etc/init.d/ceph -a killall it's working but I want stop single osd or mon
 it was not working.Please help me.

Thanks,
Ramu.

What command are you running to kill a single osd or mon?
'/etc/init.d/ceph -a stop osd.0' should work.

If it's still failing, you could change "#!/bin/sh" to "#!/bin/sh -x"
at the top of /etc/init.d/ceph to see which command isn't working.

Hi Josh,
  I tried to stop single osd with /etc/init.d/ceph -a stop osd.0.
But it was not stop.And I changed" #!/bin/sh" to "#!/bin/sh -x" also,
this is the one osd process in commandline.

Well, if that didn't do it (and I don't see the "echo -n $cmd..."
output anywhere, so if was most likely false), then it's highly likely
the PID file has gone missing or is corrupt. This is a classic failure
mode of sysvinit style self-daemonizing and PID file handling. Kill
the process manually for now, and let us know of this keeps happening;
right now "somebody rm -rf /var/run/ceph" is as good a guess as any.

This is one of the reasons why I advocate upstart/runit/etc, and why
the "new style" of deployment uses upstart.
