Was wondering why the array wouldn't stop, after some researching, appears the docker images were still mounted. cache = zfs mirrored pool. Quote Link to comment
scot Posted May 16, 2023 Share Posted May 16, 2023 Same issue here. If all of the dockers are stopped, it works properly. Quote Link to comment

The next time this issue reproduces, I'll grab diagnostics for ya. It seems to be a non-consistent issue. Quote Link to comment
bubbadrk Posted July 14, 2023 Share Posted July 14, 2023 I had the same issue. Stopped all containers and turned off Docker to edit network settings and when I attempted to start docker again it could not because the image was already mounted. I could not find support online so I rebooted, it could not unmount the share with my docker image and eventually had an unclean shutdown and reboot. Not very useful without my diagnostics but figured I would also chime in. I am on the latest release 6.12.2. Quote Link to comment
