Hi,
I've couple of days ago i added another cache pool with a brand new WD BLACK SN770 2TB disk in it, but struggling to keep it up and running. After a while, it can be 5 mins, or a ocuple of hours, the device gets thrown out of the cachepool with the message "Invalid Path" ... looking at the log of the disk IO error. I then concluded with a faulty disk, so went back to the store exchanged it for another one, came home, swapped in the new disk again, and 5 minuttes later. Invalid Path and IO error.
I have tried all the M2 slots now, so its not that, I have no issues with the other SSDS in the server. And the disk always "works" again for a limited period of time after a reboot. Its a XFS disk btw.
Anyone with the smallest of ideas of what is happening here ? Or is it just that unraid dosnt like WD BLACK SN 770 disks?
