[Bug 1840347] Re: Ceph 12.2.12 restarts services during upgrade

[Eric Desrochers]

Another thing I'm not sure about how it should react this way but worth
to explore:


     77 override_dh_installinit:
    ....
    131         # Ensure Debian/Ubuntu specific systemd units are NOT automatically enabled and started
    132         # Enable systemd targets only
    133         dh_systemd_enable -Xceph-mon.service -Xceph-osd.service -X ceph-mds.service
    134         # Start systemd targets only
    135         dh_systemd_start --no-restart-on-upgrade -Xceph-mon.service -Xceph-osd.service -X ceph-mds.service
    136 
    137 override_dh_systemd_enable:
    138         # systemd enable done as part of dh_installinit
    139 
    140 override_dh_systemd_start:
    141         # systemd start done as part of dh_installinit


Documentation:
Note that dh_systemd_start should be run after dh_installinit so that it can detect
corresponding SysV init scripts. The default sequence in dh does the right thing, this
note is only relevant when you are calling dh_systemd_start manually.

I would first try with the following to place the
dh_systemd_[enable|start] execution where it should belong.

     77 override_dh_installinit:
    ....
-   131         # Ensure Debian/Ubuntu specific systemd units are NOT automatically enabled and started
-   132         # Enable systemd targets only
-   133         dh_systemd_enable -Xceph-mon.service -Xceph-osd.service -X ceph-mds.service
-   134         # Start systemd targets only
-   135         dh_systemd_start --no-restart-on-upgrade
    136 
    137 override_dh_systemd_enable:
+               # Ensure Debian/Ubuntu specific systemd units are NOT automatically enabled and started
-   138         # systemd enable done as part of dh_installinit
+   138         dh_systemd_enable -Xceph-mon.service -Xceph-osd.service -X ceph-mds.service
    139 
    140 override_dh_systemd_start:
+               # Enable systemd targets only
-   141         # systemd start done as part of dh_installinit
+   141         dh_systemd_start --no-restart-on-upgrade

That's what I would do first and give that a try.

Title:
  Ceph 12.2.12  restarts services during upgrade

Status in ceph package in Ubuntu:
  New

Bug description:
  Upgrading from 12.2.11-0ubuntu0.18.04.2 to 12.2.12-0ubuntu0.18.04.1 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

  dpkg.log after the upgrade shows that "configure" was exercised:
  2019-08-15 10:49:18 upgrade ceph-common:amd64 12.2.11-0ubuntu0.18.04.2 12.2.12-
  ...
  2019-08-15 10:49:29 configure ceph-common:amd64 12.2.12-0ubuntu0.18.04.1 <none>
  ..
  2019-08-15 10:49:56 status installed ceph-common:amd64 12.2.12-0ubuntu0.18.04.1
