Thank you, your advice worked. 🙂
Following the initial restart, I encountered the "Unmountable: Unsupported or no file system" issue. In my efforts to resolve this problem, I made multiple attempts to remove the cache, restart the system, and then reassign it.
For educational purposes, I'm curious to know if I made any mistakes that led to this issue. Could you please explain why this problem occurred and how it wasn't automatically resolved by UNRAID?
