I wanted to prepare my running system for upgrade to omv3.
I have a running docker system with storage-driver aufs.
Due to the non existing aufs driver in newer backport-kernels in jessie I want to switch my docker to btrfs.
Therefor I prepared a btrfs formated partition and created a shared folder on it.
Stopping and deleting or loosing all running container and images is no problem, i have a backup or can rebuild them by scripts.
What is the best way to change to btrfs?
- Stopping all running container
- Change the shared folder in the Openmediavault WebInterface
- Stop docker service
- Change storagedriver in /etc/default/docker
- Start docker service
- Restore all images and container
I already tried steps 1 and 2, but nothing happened to the shared folder setting. Also after a reboot docker runs with the old folder
Is there something else i forgot?
