Thanks for the insight bro. re the disk , the specific error is "Current pending sector", re the ZFS disk/pool, yes, i messed up that cache drive, how can i undo this? re the NVIDIA driver, the compatible is still on the way, i will replace this current with that one which is compatible with the latest UNRAID version re the "raid" in unraid, yes i have a SAS in this system, thanks for highlighting that, i will be repurposing those SAS drives However, what would be the easiest path to a solution to get this server up again, it was working a few days only after i did an unclean shutdown, that started it all?
