This issue drove me nuts for weeks. I finally upgraded to version 7, and it finally fixed itself. Thanks for helping

How do I fix this?

That's the thing: the pool is already in single profile, and already balanced. However, both devices are listed. Am I missing something?

Thanks. How do I remove the missing device manually?

Here you go. Thanks hp-diagnostics-20241223-1245.zip

Thanks. It is a BTRFS pool. I did what you suggested - at least 10 times during the last 24 hours - and get the same results: Removed pool, add pool with 1 slot: Once the array starts, one drive appears missing, and the error messages pop up

Hi all, I attempted to replace one of my BTRFS cache pool NVME, configured in RAID 1. Since then, i keep getting the same errors (see title). I can only start the array if I remove the pool, create a new one with one disk. Once the array starts, those 2 error messages reaper: Unraid Cache disk messageWarning [HP] - Cache pool BTRFS missing device(s)No device identification ()warning Unraid Cache disk messageWarning [HP] - pool BTRFS too many profiles (You can ignore this warning when a pool balance operation is in progress)No device identification () I have attached the latest diagnostics. I spent hours on this with no luck, would appreciate some guidance. Thanks hp-diagnostics-20241223-0833.zip

I formatted them in btrfs. Thanks

It worked, thanks!

Here you go, thanks. For some reason, I couldn't format it as btrfs.

Hi, Enthusiastic Unraid amateur here. After trying to add a second drive to my cache pool, both drives now appear as "Unmountable: Unsupported or no file system". Tried to do a New Config, removed drives, rebooted, adding one drive, then a second one, didn't work. Diagnostics attached. Would greatly appreciate your expert guidance. Thanks all hp-diagnostics-20240928-0858.zip
