blakeslade Posted December 4, 2020 Share Posted December 4, 2020 (edited) Hello all! I've got some HDD problems and would like guidance on how to proceed. I've attached syslog and diagnostics from this morning. The situation: I have 2 drives with errors. I discovered these errors while attempting to set up Nextcloud using spaceinvaderone's YT instructions when I couldn't get nextcloud to start. I know it's unrelated to the drive failing. I have a 9TB array: 1 x 3TB parity and 3 x 3TB drives (screen: 'Array_drives'). I took the array offline and remounted in maintenance mode and am currently running Read-check which is 4.1% complete. I also have the extended SMART check running on both drives. I have ordered replacement drives (4 x 6TB WDC WD6002FRYZ) so I will replace and upgrade at the same time once they arrive next week. I'd like to know how to proceed from here? 1) Until the drives arrive, what steps do I take in preparation? 2) What steps do I take to replace and upgrade the drives? My plan is to have 2 x 6TB parity and then 12TB array (2 x 6TB) and a 2 x 3TB cash pool Thank you so much for your advice and I appreciate all you help! tower-diagnostics-20201204-0759.zip tower-syslog-20201204-1258.zip Edited December 10, 2020 by blakeslade Quote Link to comment
JorgeB Posted December 4, 2020 Share Posted December 4, 2020 Issues with multiple disks, check/replace cables on disks 2 and 3 then post new diags (after array start in normal mode). Quote Link to comment
blakeslade Posted December 4, 2020 Author Share Posted December 4, 2020 On it. No back up cables so I'll order replacements and report back when I have new diags. Quote Link to comment
blakeslade Posted December 8, 2020 Author Share Posted December 8, 2020 (edited) Cables replaced on disk 2 and 3! Issues with disk 3 now appear to be resolved. disk 2 is still being reported as "disabled", see screen below. I am running the Extended SMART scan on disks 2 and 3. What additional diagnostics should I run for disk 2? My new HDD's arrive this week, what steps do I follow to upgrade from my current setup? What would be an optimal set up for 4 x 6TB drives and 3 x 3TB drives (assuming disk 2 is finished)? Thanks! Edited December 8, 2020 by blakeslade 1 Quote Link to comment
blakeslade Posted December 8, 2020 Author Share Posted December 8, 2020 Did some reading (oh oh) here, https://wiki.unraid.net/Troubleshooting#Re-enable_the_drive All SMART tests have passed (took the liberty of doing parity and Disk 1). - Reallocated_Sector_Ct, Current_Pending_Sector, and UDMA_CRC_Error_Count Raw_Values are '0' So, I've followed the safe instructions to rebuild the array and am waiting for the process to complete. Thanks for your help JorgeB! tower-diagnostics-20201208-1532.zip Quote Link to comment
