Docker will not start when i stop convoy

[jhmnieuwenhuis]

Hi, I want to uninstall convoy. I disabled and stopped the convoy service and the docker service. I removed the spec file : /etc/docker/plugins/convoy.spec

But when I try to start docker again i get an error level=warning msg="Unable to locate plugin: convoy .."

I deleted all convoy volumes

[root@csdevel rancher]# docker volume ls DRIVER VOLUME NAME local dev_dev-html-volume local dev_dev-mailhog-volume local dev_dev-psql-volume local dev_drupal-backup-volume [root@csdevel rancher]# convoy list {}

What am I doing wrong ? Centos 7 Docker 17.07.0-ce convoy v0.5.0 #

Extra Info

If I stop convoy and try to restart docker, I see the following error : [root@csdevel ~]# systemctl status docker -l ● docker.service - Docker Application Container Engine Loaded: loaded (/usr/lib/systemd/system/docker.service; enabled; vendor preset: disabled) Active: activating (start) since Sat 2017-09-16 20:14:26 CEST; 2min 29s ago Docs: https://docs.docker.com Main PID: 8445 (dockerd) Memory: 15.2M CGroup: /system.slice/docker.service ├─8445 /usr/bin/dockerd └─8453 docker-containerd -l unix:///var/run/docker/libcontainerd/docker-containerd.sock --metrics-interval=0 --start-timeout 2m --state-dir /var/run/docker/libcontainerd/containerd --shim docker-containerd-shim --runtime docker-runc

But docker volume ls shows no convoy volumes and convoy list is empty :

[root@csdevel ~]# docker volume ls DRIVER VOLUME NAME local dev_dev-html-volume local dev_dev-mailhog-volume local dev_dev-psql-volume local dev_drupal-backup-volume [root@csdevel ~]# convoy list {}

Solution Finaly found a solution cd /var/lib/docker/volumes rm metadata.db systemctl restart docker

So it seems the metadata.db was somehow corrupt....
