sonofdbn Posted June 24, 2018 Share Posted June 24, 2018 While I was away there was a power glitch and fortunately the UPS shutdown the array gracefully. But on rebooting, I got CRC errors and disk read errors on one of my data disks. From reading around, it seems that CRC errors are possibly not too serious. However, disk read errors might be an issue. My diagostics: tower-diagnostics-20180624-2153.zip  Should I replace the drive? If it's recommended that I replace the disk, which is 4TB, can I just swap in an 8TB drive and rebuild? Link to comment
JorgeB Posted June 25, 2018 Share Posted June 25, 2018 SMART looks OK, run an extended SMART test on that disk, if OK swap/replace cables and monitor. Link to comment
sonofdbn Posted June 25, 2018 Author Share Posted June 25, 2018 Thanks so much for the help. Ran an extended SMART test and the disk passed. So I shutdown, changed the cable and restarted. Now I get a nice notification telling me that "array turned good. Array has 0 disks with read errors." Link to comment
JorgeB Posted June 25, 2018 Share Posted June 25, 2018 That will rule out the cable, so keep monitoring. Link to comment
