CtznSnips Posted August 31, 2023 Share Posted August 31, 2023 yoda-diagnostics-20230830-2029.zip This seems to happen to me every 6-8 months - out of nowhere I get disk errors but the disks themselves seem fine. Usually I can resolve it by re-seating cables. Yesterday I got errors on a couple of disks, I tried to re-seat cables and start the array back up but I continued to get errors. I had a back-up HBA card and cables so I tried replacing those which worked while I restored one disk. The restore completed successfully, so I started to rebuild parity, then again I started getting errors. I'm running out of ideas here, any help is appreciated. Quote Link to comment
Solution JorgeB Posted August 31, 2023 Solution Share Posted August 31, 2023 Looks more like a power/connection problem, try replacing the cables or using a different PSU if available. Quote Link to comment
CtznSnips Posted August 31, 2023 Author Share Posted August 31, 2023 (edited) Thanks for your help. Turns out there were 10 drives powered by the same PSU cable (with 3 SATA power connecters) using splitters. I guess when I built this server 4 years ago I didn't know any better. I spread the 10 drives across more cables and removed some splitters. So far the rebuild is at 18% without issues. Hopefully this fixes it for good. Is there a general rule for splitting SATA power and how many drives you can power per connection directly from the PSU? Maybe I should look into a new power supply...? I have 8 drives being powered now on 6 SATA power connectors direct from the PSU. Edited August 31, 2023 by CtznSnips Quote Link to comment

This should be OK, though when possible it's always good to avoid power splitters, if you need to use them I recommend to don't split one SATA port for more than two disks. Quote Link to comment
itimpi Posted August 31, 2023 Share Posted August 31, 2023 If you must use power splitters it is normally better to use molex->SATA ones if you PSU has molex connectors has molex is rated for a higher current draw. Quote Link to comment
