Docker error on start

[Maykonn]

When I try to start docker on Mac, docker ask to diagnose, result:

Thanks for the bug report. Did you recently upgrade Docker for Mac from a previous beta version? It looks like there is evidence of block corruption in the qcow file:

 Docker[com.docker.driver.amd64-linux][30848] <Notice>: com.docker.hyperkit: [ERROR] Found two references to cluster 275849: 274040.22448 and 210.8808
Docker[com.docker.driver.amd64-linux][30848] <Notice>: com.docker.hyperkit: [ERROR] Mirage block device raised exception: (Failure "Found two references to cluster 275849: 274040.22448 and 210.8808")

This means that the app is failing to start after failing the integrity checks. There were some known issues with upgrade in this regard. As a workaround we recommend either uninstalling and reinstalling the application or rm ~/Library/Containers/com.docker.docker/Data/com.docker.driver.amd64-linux/Docker.qcow2, then restarting. Unfortunately containers and images will need to be rebuilt after this since it will be a fresh instance of Docker for Mac.

I just installed the Docker from docker website and after some days started giving error.
I uninstall and re-install and works now.

Thanks for the update @Maykonn. We've got a few internal issues tracking the storage corruption, which is thankfully quite rare. I'll close this issue for now as a dup of #1159. Glad to hear it is working for you after a reinstall!
