sketchy Posted August 13, 2018 Share Posted August 13, 2018 (edited) My parity disk is showing as having read errors in Fix Common Problems and errors under the main page: In the system log: Aug 13 15:34:43 Tower kernel: print_req_error: I/O error, dev sdg, sector 4983868568 Aug 13 15:34:43 Tower kernel: md: disk0 read error, sector=4983868504 I'd guess read errors at a couple of hundred sectors. The disk has not been disabled and both short and extended SMART tests have passed (disk smart report attached). I have performed two parity checks last check today finding 0 errors. Attached is also the full diagnostics. Am i right in saying that these bad sectors are likely to increase in number and that i should start thinking about replacing this disk? tower-smart-20180813-2018.zip tower-diagnostics-20180813-2019.zip Edited August 16, 2018 by sketchy Marked as solved Quote Link to comment
JorgeB Posted August 14, 2018 Share Posted August 14, 2018 That disk is failing, it might have passed SMART but there are a lot of raw read and multi zone errors, as well as UNC errors on the SMART report, you should replace it, IMO sooner rather than later. Quote Link to comment
sketchy Posted August 14, 2018 Author Share Posted August 14, 2018 Thankyou @johnnie.black for checking the smart report. I will replace this disk. Quote Link to comment
sketchy Posted August 16, 2018 Author Share Posted August 16, 2018 Incase this helps others. I received guidance under another thread to free up a data disk and use in place of the failing parity disk. Quote Link to comment
