Machine crash corrupted Docker.qcow2?

Docker Desktop
1

Expected behavior

Machines do sometimes still crash/freeze, especially if they’re a Macbook 12". A crash (spinning beachball after wake, had to force power off) seems to have left my Docker for Mac in a corrupt state, it won’t start up.
A crash should not corrupt the docker installation or lose images.
Ideally I’d be able to restart containers, unless their volumes became corrupt?

Actual behavior

I guess I have to re-init my environment and rebuild/download images.

Steps to reproduce the behavior

  1. But an underpowered, overpriced machine and try to run a docker environment.
  2. Be surprised it works, then try to push it too hard by building and running too much. Close lid for a while, open it, see it freezes when waking.
  3. Exit and reopen the Docker app, do a pinata restart, no errors reported but docker ps just hangs.

I actually just had this happen to me as well… except I was just running one container and hammering it with thousands of http requests.

Just had this problem happen again. Crash on latest Version 1.12.0-rc2-beta16 (build: 9493) leads to a corrupt docker that never starts.
