Unraid 6.12.2 - After Update one Disk is "Not Installed"

[somethingnew71]

After updating to the newest version of Unraid one of my drives suddenly started getting listed as "Not Installed". The drive still shows all the states associated with it except the Temp, Reads, Writes, and Errors. The file system, Size, Used, and Free are all still viewable and I can look through the directory structure. Any ideas as to why this happened?

 

The weirdest part is there is no historical device information for that drive and when I try to assign the installed drive it doesn't show up in the drop down of selectable drives.

Has my drive actually failed or is this related to the software update somehow?

Check/replace cables for that disk to see if comes back online, if it doesn't you will need to replaced it, and unlikely that this has anything to do with the OS update.

This will be because Unraid is ‘emulating’ the missing drive using the combination of the other data drives plus parity drive.   When you put in a replacement for the drive what is showing on the emulated drive is what will be rebuilt onto the replacement dtive.

Thanks for the education guys! Yup I swapped out for another new iron wolf drive and it recognized right away so this one must have just hard crashed/died. It was a 2017 WD Red drive. Lived a good life!
