This was going fine for me until the last moment, when I got the following super-useful error message: Error response from daemon: Cannot destroy container 1cd705ffc49f5ce0622614316e3a742b8e6c8a77362528338db30a6f352477d2: Driver devicemapper failed to remove root filesystem 1cd705ffc49f5ce062261431…

[画像] Manually update Discourse and Docker image to latest but you are on your own here I’m using the standard “by the book” installation using the docs provided here and a Digital Ocean server, as recommended.

Nope, device mapper is not supported, never was. You MUST get aufs working.

Looks like I have the same problem reported here: https://meta.discourse.org/t/discourse-did-not-restart-after-system-crash/24494/5?u=downey So be careful installing normal updates to your OS, apparently it breaks Discourse. :stuck_out_tongue:

Supposedly docker 1.5 will make device mapper more reliable, on the fence on this cause I heard this many time before.

I am curious, how were you updating Ubuntu? I tend to update Docker on mine every few months so perhaps that’s why I didn’t see any regression on kernel / aufs: apt-get update apt-get dist-upgrade lxc-docker

I think to recover, you’ll have to manually docker rm/rmi the leftovers, then rebuild. Quick overview of that: docker images -a # identify useless images (old discourse base, untagged), then docker rmi d25ec275fb1d 818beea55263 cdb5237bc8a7 docker ps -a # identify dead/defunct containers, then do…

[画像] codinghorror: I am curious, how were you updating Ubuntu? Just using apt-get upgrade and upgrading all packages every few weeks. As mentioned in the other thread, it’s hard to say when aufs went away, it was surely in a kernel upgrade at some point, and then this is likely the first doc…

Hi folks. I’ve hit that snag too. Basically, ensure you have linux-image-extra-virtual and aufs-tools installed add to /etc/default/docker something like this DOCKER_OPTS="-s aufs" I wrote a blog post about it here but the steps above is all you need. really.

Device mapper is not supported, please get aufs working.

You could probably recover by rebooting, but you are on your own here.
