Hello together

I have 3 4TB disks in a RAID5 in the unit, which are in their 5th year of life. So far no problems. The Icy Box is connected to a headless Ubuntu server.
I would now like to read out the S.M.A.R.T. data. But when I need smartctl under Ubuntu, it only says that the data is not available. Does anyone have an idea how to get the information? (Yes, the disks have S.M.A.R.T.).

Thank you!!

Answer

I can't imagine that this works and I can't find a hint in the manual. I assume that the box has its own logic for reporting hard disks as defective and hope that this does not happen at the last minute. But it seems to me that the whole thing is hijacked from the outside.
