linusgrip Posted August 4, 2019 Share Posted August 4, 2019 (edited) Hi! Woke up one day and my unraid box had a unclean shutdown. After paritysync (with correction) it got 256 sync errors. Took everything offline and did memtest for 40hours with no errors and stressed the CPU for 12h with no problems. Don´t know if i had any poweroutage, (ordered a UPS yesterday....) replaced the SATA cables and turn her back up and did another parity check (with correction). Got same 256 errors. Could someone help we with this, can´t see any errors on disk, or not able to find in the log. Should i do a parity rebuild or is that stupid. Maybe preclear the parity drive and then rebuild if complete the preclear without errors. Ofcourse i did not preclear any of my drives brefore installing them.... Lesson learn there.

All best! // Linus unraid-syslog-20190804-1821.zip unraid-smart-20190804-2040_Disk2.zip unraid-smart-20190804-2040_Parity.zip unraid-smart-20190804-2040_Disk1.zip Edited August 4, 2019 by linusgrip Forgot system info Quote Link to comment
JorgeB Posted August 5, 2019 Share Posted August 5, 2019 Some sync errors after an unclean shutdown are normal, even expected. Quote Link to comment
linusgrip Posted August 5, 2019 Author Share Posted August 5, 2019 Yes but what is best practice, complete rebuild of parity? Quote Link to comment
JorgeB Posted August 5, 2019 Share Posted August 5, 2019 Correcting parity check. Quote Link to comment
linusgrip Posted August 5, 2019 Author Share Posted August 5, 2019 Thing is i did a parity check with correcting and found 256 error. Then ran the memtest/cpu stress. After that another parity check and found exactly 256 error again. Quote Link to comment

Most likely first one was non correct, but would need the diags to confirm, by default the check after an unclean shutdown is non correct. Quote Link to comment
linusgrip Posted August 5, 2019 Author Share Posted August 5, 2019 I'll run another check. Download diagnos and then run another. Thanks johnnie for the support 😃 best thing about unraid, all the good ppl in the community. Quote Link to comment
linusgrip Posted August 5, 2019 Author Share Posted August 5, 2019 Ran last run now without any erros so i guess am golden then I´ll attach the log again if you got some time over to look over if i missed anything. Many thanks again johnnie! unraid-diagnostics-20190805-2239.zip Quote Link to comment
