Sigh. I ran the "New Permissions" tool in unRAID and of course i ran it across all the disks, as it suggests. I neglected to read carefully enough. ☹️

I restored my Dockers thanks to this post: https://forums.unraid.net/topic/177037-completely-screwed-up-ran-new-permissions-on-every-share-including-appdata-now-no-containers-work-with-execution-error-bad-parameter-message/#findComment-1544109

I have also run Fix Common Problems which tells me there's nothing for me to fix.

Is there anything anywhere else that might be screwed that i need to attend to? system or domains ?

Thanks for any advice offered.

EDIT: If you use "search" to find "permissions" it comes up with some OLD tool! If you manually go to Tools > Docker Safe New Permissions - then you're better protected! How should this be reported to devs?

"New Permissions" via search:

Typically only appdata will be a problem, you may need to recreate the containers.

The Docker Safe New Permission is not part of standard Unraid. It is added (I think) by the Fix Common Problems plugin.

Oh ok. Makes sense. One must wonder why the original (?) is still implemented the way it is. It includes text for people upgrading from version 5.x which i think implies it hasn't been looked at for many years.
