[Bug 1654600] Re: unattended-upgrade-shutdown hangs when /var is a separate filesystem
Hello, Yes, I am fully aware that my /var/run->/run replacement in that script is a hack. To be clear I am not testing in Zesty but Ubuntu 16.04.2 LTS Xenial. The setup is following: /dev/sda1 on / type xfs (rw,relatime,attr2,inode64,noquota) /dev/sdc on /var type xfs (rw,relatime,attr2,inode64,noquota) Every single machine we (my and my colleague) tested with the updated unit still hangs. As var as I can tell they never reboot. I have posted a question regarding this issue to systemd mailing list, and one of the responses was the following: """ > [Unit] > Description=Unattended Upgrades Shutdown > DefaultDependencies=no > Before=shutdown.target reboot.target halt.target network.target > local-fs.target Well, you order if before local-fs.target, which means it is stopped after local-fs.target. You get exactly what you ask for. If this is wrong, fix unit definition, but we do not really know what is appropriate for this service. > Documentation=man:unattended-upgrade(8) > > [Service] > Type=oneshot > RemainAfterExit=yes > ExecStop=/usr/share/unattended-upgrades/unattended-upgrade-shutdown --debug > TimeoutStopSec=900 > > [Install] > WantedBy=shutdown.target > > It appears no one who is involved in this fix understands systemd (which is > very worrying!). > > How does one would fix this unit so it is ran before the file systems get > unmounted? > Order it After=local-fs.target """ "Obviously" according to systemd mailing list if I want to things to run Before I need to use After! So I believe the confusion is with what exactly Before and After mean in systemd units. Today I will be testing various combinations with After/Before to see if I can make sense of it. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1654600 Title: unattended-upgrade-shutdown hangs when /var is a separate filesystem To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/unattended-upgrades/+bug/1654600/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 1654600] Re: unattended-upgrade-shutdown hangs when /var is a separate filesystem
I have tested this and it does NOT work. I fixed the issue in couple of different ways: One way is completely remove the unit (who in right mind does install updates during reboot on production servers?). I will be actively doing that on all machines I encounter. Another way is this: sed -i 's#/var/run/#/run/#g' /usr/share/unattended-upgrades/unattended-upgrade-shutdown So the problem with that sed is that the logging part will fail. So not really a solution. Systemd has proven to be inconsistent pile of crap so far... I could not make systemd to run this unit before local-fs.target.
