ObviousViking Posted December 16, 2022 Share Posted December 16, 2022 Hi all after some help please with a slow parity check. so my array was all fine and then i got some errors on disk 11, unraid disabled the disk. i did a new config to re-enable the disk and also did a smart check which passed. i kicked off the parity rebuild and am seeing speeds of at max 5MBps but usually hovering around the mid 100kbps range and im seeing at times only 1 drive being read from. server is a 16 bay rack style with sas backplane, i tested the connections and seem fine. also if anyone has a link to a guide on where to look for stuff in the unraid diagnostic files id be up for brushing up. hercules-diagnostics-20221216-2234.zip Quote Link to comment

ObviousViking Posted December 17, 2022 Author Share Posted December 17, 2022 ah thanks for that. it has started to speed up the rebuild and a new drive is due in a day so should be able to do a swap and sort it out. is this smart log saying too many bad sectors which is giving the write errors?

JorgeB Posted December 17, 2022 Share Posted December 17, 2022 SMART shows a failed long test which means the disk needs to be replaced. Quote Link to comment
