#498 upgrading CAH `7.1711` -> `7.1803` docker daemon fails to start
Opened 5 years ago by dustymabe. Modified 5 years ago

Started the CentOS Atomic Host vagrant box I have lying around on my system. It was the 7.1711 version. It starts fine but after I upgrade docker service doesn't come up. I see two issues:

  • docker-storage-setup fails

We probably need to address these issues.

In general, I'm not sure about filing atomic-wg issues that relate to CentOS because we can't generally fix them without going through RHEL, right?

Anyways https://bodhi.fedoraproject.org/updates/FEDORA-2018-03bdc0733a is the Fedora version of the first one. This fix needs to go through the whole downstream thing.

For the pool issue...I think that deserves a bug against docker in RHEL? Though of course that sort of wants to have reproduced it against RHELAH first.

That said it's definitely possible with some of these things that it's CentOS-AH specific as some of the metadata gets important.

You are right, but I think it's mostly a philosophical question. Filing issues here helps bring awareness to the issues I believe. For me things get too easily lost in bugzilla.

+1, thanks

probably

Right. To me this is as good a place as any to "route" issues and find the most effective way to get them resolved. Whether they are specific to Fedora, specific to CentOS, or specific to RHELAH and need their own BZ. Maybe I'm created too much overhead. Maybe not..

I understand that why docker-storage-setup error message is coming and how upgrade will fix that. What I don't understand is that why docker is complaining that "atomicos-docker--pool" does not exist.

If storage is already setup, then this thin pool should have come up automatically after reboot. If its not there, then we are looking at a different issue.

What's the output of "lvs", "vgs", "pvs" and "lsblk" command on the system.

just tried to reproduce and I only see the first error this time and the docker service itself seems to come up ok.. Maybe a race condition? I can try to play around and see if I can repro.

and just rebooting that same host allows me to reproduce:
