Subject: [PATCH] purge: do not stop ceph.target on each daemon
MIME-Version: 1.0
Content-Type: text/plain; charset=utf8
Content-Transfer-Encoding: 8bit

Doing this cause some all the daemons to go down at the same time. In a
scenario where we colocate a monitor and an osd, this osds will take
some time to go down which will make the 'umount' task fail.
