[Bug 1477225] Re: ceph-radosgw restart fails

Fri Sep 4 13:39:52 UTC 2015

** Description changed:

  [Impact]

  On 14.04 the restart target of the sysvinit script brings the service down
- but almost always fails to bring the service back up again.
+ but sometimes fails to bring the service back up again. There is a race between stop and start and in the failure case the attempt to bring the service up runs before the service has been stopped and the start command is never issued:

  The proposed fix updates /etc/init.d/radosgw so that the stop target
  waits for up to 30 seconds for the service to stop cleanly

  [Test Case]

- sudo apt-get install --yes radosgw
- sudo mkdir /etc/ceph
- sudo su -
- cat <<-EOF > /etc/ceph/ceph.conf

  [Regression Potential]

   * The only change in behaviour that would result from this change is that
     running the stop target in the init script will wait for up to 30s before
     exiting rather than retuning immediatly. I cannot think of any use cases
     where this would be an issue.
