I was trying to stop the array, like always I turned off the docker first, then after few minutes I pressed Stop Array, it stuck like that for 30 min, I was able to log via webgui/ssh etc I just could not stop it. I really need to get to the bottom of it as I do not shut my server ofter(once every 1/3 months) but I need it to be reliable I cannot do parity checks everytime i shut it down because I have to force a shutdown.

Please see attached diagnostics - generated when it was stuck, also this was the end of the LOG:</

Disable Docker and VM service and reboot in safe mode, start the array and see if it stops, if yes, retest again after booting in normal mode to rule out a plugin issue, leave the services still disabled, if still OK enable one of the services and retest, then the other, note that if the issue happens with the docker service enabled only, you may need to try enabling one or a few containers at a time to find the culprit.

Actualy I found the issue, I have share mounted from my other NAS, if I power it down without unmounting first in unraid, then it won't be able to stop the array.
