Erym Posted July 5, 2022 Share Posted July 5, 2022 Hello, I'm not really used to unraid, and I just had an 8TB drive go disabled after, apparently, 512 read errors. I got this notifications : - "Array has 1 disk with read errors" - "Alert [TOWER] - Disk 2 in error state (disk dsbl)" I've stopped the entire array immediately. Some of my disks begin to have udma crc errors recently (including the disabled disk 2), I suspect the poor-quality sata cables, which i've planned to change. Can someone please review diagnostics and provide any insights? (Sorry for my poor English !) unraid-rb-diagnostics-20220705-0826.zip Quote Link to comment
Solution JorgeB Posted July 5, 2022 Solution Share Posted July 5, 2022 Yes, it does look like a power/connection problem, disk 1 also showing similar issues, replace cables and rebuild. Quote Link to comment
Erym Posted July 5, 2022 Author Share Posted July 5, 2022 Thanks for the answer, i just have to restart the array, and let the system rebuild ? Quote Link to comment
JorgeB Posted July 5, 2022 Share Posted July 5, 2022 After replacing the cables start the array and check that the emulated disk is mounting and contents look correct, then you can rebuild on top: https://wiki.unraid.net/Manual/Storage_Management#Rebuilding_a_drive_onto_itself Quote Link to comment
