June 17, 20251 yr Hi, I have a dual CPU server from Lenovo. Main board: LENOVO 00YL827, CPUs: 2X Intel® Xeon® CPU E5-2620 v3after setting the on onboard SAS raid controller to jbod mode all drives showed up and unraid worked for like 4 months now. But recently it started to fail to read from disks. I changed 3 of them already. An hour ago I changed one 750 GB hard drive to a brand new 1 TB hard drive. Data rebuild was really slow (talking like 2 mb/s and 8 days until finish). Like 50 minutes unto data rebuild, unraid cant read from the newly inserted disk anymore. I tested the disk on my pc and did some analysis before putting it in the server.The new disk I installed: ST1000LM048-2E7172_ZKP5YDYE-diagnostics-20250617 disk3 (sdh)I have also tested all other drives I changed and all of them are okay. Except of one but that is a really old and worn down drive. But again unraid cant read from the drives and after like 300 read errors cuts out the drive completely.I have the thought that unraid isn't working right anymore, and it's just wasting my money in new drives.If this matters:the server room has an ambient temperature of around 30 °C atmCan someone help me with the issue?tower-thomas-diagnostics-20250617-1759.zip Edited June 17, 20251 yr by 1euro7cent Added the drive in question
June 17, 20251 yr Looks like disk 3 dropped offline, could be power/connection related - try powering down, re-seating it then post diagnostics again
June 17, 20251 yr Author Ive shutdown the server, reseated the drive and started it. the drive appeared again. but i cant select it for reconstruction tower-thomas-diagnostics-20250617-1842.zip
June 17, 20251 yr Author i followed this: https://docs.unraid.net/unraid-os/manual/storage-management/#rebuilding-a-drive-onto-itself and it is being reconstructed now at ~150-200 mb/s
