jdubbs23 Posted February 29, 2020 Share Posted February 29, 2020 We had a power failure and when unraid came back up it automatically started a parity check. A couple hours into the parity check some errors occurred and unraid disabled the parity drive. Not sure what to do, I ran a SMART check on the parity drive and it looks OK. Should I just re-enable the parity drive? Diagnostics attached and latest SMART report. tower-diagnostics-20200229-2001.zip Quote Link to comment

jdubbs23 Posted March 1, 2020 Author Share Posted March 1, 2020 Thanks. I hadn’t done an extended diagnostics on the drive and that was still running when I originally posted. Any thoughts on what to do about the parity drive? Think it’s OK and I can just re-enable it? Quote Link to comment
JorgeB Posted March 2, 2020 Share Posted March 2, 2020 Diags are after rebooting so we can't see what happened, but the disk looks fine, swap replace cables to rule them out (especially the SATA cable since there are a few CRC errors) then re-sync parity. Quote Link to comment
jdubbs23 Posted March 3, 2020 Author Share Posted March 3, 2020 OK thanks for the review. I went to do the parity rebuild (stopped the array, removed the parity drive, started the array, stopped the array, added the parity back, started the array), and got errors again like before. New diag file attached which should contain everything because I didn't restart the server yet. Full disclosure, I didn't replace the SATA cable as you suggested, so maybe that really is the issue. Just seems bizarre to have happened out of nowhere because I haven't opened the case or changed anything in several months or more. tower-diagnostics-20200303-0148.zip Quote Link to comment
JorgeB Posted March 3, 2020 Share Posted March 3, 2020 Errors look like a connection problem, most likely the SATA cable since CRC errors went up, you would be notified of that if system notifications were enable. Quote Link to comment
