January 16, 20224 yr I received a notification from unraid saying "Array has 1 disk with read errors". Disk 1 has been disabled and it says it has 10 errors. I have attached the diagnostics file. I also have the syslog file donwloaded, shoud i upload it as well? I have not done anything with the server after getting the error, please let me know how to proceed. osiris-diagnostics-20220116-0314.zip
January 16, 20224 yr Author I shut the server down, checked the cables and started it again. The SMART data attributes look good, i think, and it says SMART overall-health:Passed. I also got a notification saying "array turned good" and it now shows 0 errors in the main tab. What do i do now? With the array started the disk is still disabled, do i have to initiate a rebuild to get the data back? Or should i start a "Check" as seen in the second image?
January 16, 20224 yr I think you were onto something with the cables...if you've made sure the attachment is clean and you still have issues, I'd replace the cables themselves and see if your issue persists. I've had something similar happen in a Gentoo install I had at work...similar error messages that you have inside your diagnostics. In my case, it was a loose SATA cable. I'm newer to unraid so I can't really answer the 'next steps' question. I'm sure there are others who know what should be done (at least I hope there are) Edited January 16, 20224 yr by devnet
January 16, 20224 yr Community Expert Disk dropped offline, this is usually a power/connection problem, if the emulated disk is mounting and contents look correct you can rebuild on top: https://wiki.unraid.net/Manual/Storage_Management#Rebuilding_a_drive_onto_itself

If it happens again I'll be switching out the cables. Thanks for the help!
