September 11, 20232 yr I've done some research on this but I can't see anything to help me. Each time my array restarts I loose all my dockers, if I add them back they work fine with persistant data / config. I'm sure this is me, something I've done, I just can't see what. Thanks you in advance. Doowle unhump-diagnostics-20230911-1837.zip

No custom scripts. If one exists in the array, would that stop it moving to the array?
September 11, 20232 yr Author I did a stupid / bad thing. I just removed the system and domain folders in /mnt/user, thinking they didn't need to be there (there was a docker.img) there. Now it won't shut the array down!

If it's not stopped by the time I am back, what to do.. D
September 11, 20232 yr Community Expert Doing that would have removed files docker was trying to use such as docker.img which is in the ‘system’ share. I think you are going to have to force a shutdown by holding down the power button.
September 12, 20232 yr Author FWIW, my mad and dumb approach seemed to work. thank you for putting me on the right track. J
