Bug description:
[Impact]
Upgrading from ceph on Ubuntu 18.04 causes the ceph-osd services to be
restarted without prompting.
This appears to be in the configure section on the ceph-common,postinst:
# Automatically added by dh_systemd_start/11.1.6ubuntu2
if [ "$1" = "configure" ] || [ "$1" = "abort-upgrade" ] || [ "$1" = "abort-deconfigure" ] || [ "$1" = "abort-remove" ] ; then
if [ -d /run/systemd/system ]; then
systemctl --system daemon-reload >/dev/null || true
if [ -n "$2" ]; then
_dh_action=restart
else
_dh_action=start
fi
deb-systemd-invoke $_dh_action 'ceph.target' >/dev/null || true
fi
fi
# End automatically added section
This is a change of behaviour compare to debhelper 9.
--restart-after-upgrade is the default in compat 10.
The expected behavior during a package upgrade is to leave all the
ceph service states unmodified. They should not be enabled/disabled or
stopped/started.
[Test Case]
* Check pid of ceph-osd (before upgrade)
* sudo apt-get update
* sudo apt-get upgrade
* Check pid of ceph-osd (after upgrade)
If the pid changes, it means ceph-osd has been restarted, and the
restart or stop/start has been exercised.
[Potential Regression]
Low, the desire is to control the precise timing of the restart.
The larger context is that there may multiple updates (in this case
kernel) and one want a single stop/start when the reboot occurred.
The goal is for the admin to choose when (and which) ceph services
move to the new code level.
