Permanently deleting devices?

[Fogey]

A few years ago, when I first started with UnRaid, I followed Spaceinvader One’s videos on setting up a Cache pool. Unfortunately, as a newbie, I made a mistake and instead of setting up 2 separate cache pools, I set up one cache pool with 2 drives.

 

I quickly realised and reversed my steps and deleted the 2 drives and set it up properly.

 

However,  every time I take the array off line and then bring it back on I get 2 Red Warnings from Fix Common Problems “Invalid folder (name of deleted device) contained within /mnt”, on warning for each of the old devices I'd deleted.

 

It’s not a big deal to resolve this - Midnight Commander gets me to /mnt and I can easily delete the 2 old devices. But this is only a temporary solution as the errors come back the next time the array starts.

 

My question is  - I know I screwed up initially, but is there some way that I can delete these 2 devices permanently?

 

Thanks for your help
