gooner_47 Posted January 2, 2019 Share Posted January 2, 2019 Please can someone help me analyse the attached diagnostics? Thanks, Luke tower-diagnostics-20190101-2220.zip Link to comment
JorgeB Posted January 2, 2019 Share Posted January 2, 2019 Diags are after rebooting, but SMART looks fine and there are some CRC errors, so likely a cable problem, replace SATA cable and re-sync parity. Link to comment
gooner_47 Posted January 5, 2019 Author Share Posted January 5, 2019 Thanks for this, I have replaced the SATA cables. How do I re-sync parity? Link to comment
gooner_47 Posted January 5, 2019 Author Share Posted January 5, 2019 I found Parity Check in settings, which I scheduled and it's now running. Is this the correct process? Link to comment

Not really. I'm not sure what it would do if you did parity check on a disabled parity disk. Did you check the box telling it to correct parity errors? Post new diagnostics and a screenshot of Main - Array Operations just for my curiosity. Link to comment
gooner_47 Posted January 5, 2019 Author Share Posted January 5, 2019 What should I have done then? Yes I checked that box. Should I cancel the parity check? tower-diagnostics-20190105-1217.zip Link to comment
trurl Posted January 5, 2019 Share Posted January 5, 2019 It says Read-Check in progress and no corrections so far in syslog. So I'm pretty sure it won't fix your "red cross". Resync parity is just another way of saying rebuild parity. The procedure to rebuild a disk to the same drive, whether parity or data, is the same. Stop array Unassign disk Start array with disk unassigned Stop array Reassign disk Start array to begin rebuild Link to comment
gooner_47 Posted January 5, 2019 Author Share Posted January 5, 2019 Rebuild started. It's still warning me about the CRC errors, despite replacing the SATA cables: Link to comment
JorgeB Posted January 5, 2019 Share Posted January 5, 2019 If CRC errors continue to increase there's still a problem, try another SATA cable, then another SATA port and/or enclosure if you have one. Link to comment
trurl Posted January 5, 2019 Share Posted January 5, 2019 Click on the SMART warning indicator for that disk on the Dashboard and acknowledge it. 19 is the number of CRC errors in your original diagnostic so it doesn't look like they are increasing. After acknowledging that warning, it shouldn't give it again unless they increase. Link to comment
