Pandasoft Posted January 15, 2023 Share Posted January 15, 2023 Hi All, My first time posting so I'd like to start by saying thanks for the software - it's exactly what I've been looking for and I've learnt so much getting it up and running using numerous articles from here. I now have my unraid server performing automatic backups for my hybrid windows and linux environment plus many other things. This morning however I woke to find all my backups had failed. Further investigation showed my server was totally unresponsive. I rebooted and it failed to come up - it sat at the unraid boot options, appeared to try and boot but seemed to fail at loading /bzroot and then quickly returned to the boot options screen. Eventually I rebooted again and selected safe mode with gui from the boot screen and this time it came up no problem. I was able to start the raid successfully and the dockers also started. So I shut everything down properly and rebooted once more and this time it booted properly again in normal mode. Since then, I have rebooted again and it has again failed to boot, but I managed to capture the error as shown in screenshot but summarised to cannot open root device - please append a correct root = boot option I am hoping someone can confirm that this is simply a failing USB boot drive and I can just replace it and restore my latest backup, but before I try that, I thought I would ask. Any help would be great - Thanks in advance Paul Quote Link to comment
Solution JorgeB Posted January 15, 2023 Solution Share Posted January 15, 2023 This is usually a flash drive problem, try re-creating it. Quote Link to comment
Pandasoft Posted January 15, 2023 Author Share Posted January 15, 2023 Thank you - that's what I was hoping. I'll build a new one and if it solves the problem, I will come back and mark the solution. Thanks again Quote Link to comment
Pandasoft Posted January 15, 2023 Author Share Posted January 15, 2023 USB replaced and server rebooted fine so far. Hopefully that's it all sorted now. Quote Link to comment

Sometimes just rewriting the files to the flash drive can fix this sort of problem. It is as if that rectifies any sectors that are borderline on reading successfully. Quote Link to comment
Pandasoft Posted January 16, 2023 Author Share Posted January 16, 2023 Just in case anyone else discovers this thread - recreating the USB worked fine, but what I didn't realise was that my Unraid server had not connected to my domain after the USB change as the domain account password doesn't seem to be saved. So, just a heads up that you need to reenter the domain user password to rejoin the domain. Quote Link to comment
Michigan1112 Posted July 20, 2023 Share Posted July 20, 2023 (edited) Hello there. I have been through 3 different usb drives. (No not SanDisks). I keep getting that same error. I bounce it a few times then it’s fine. It will even throw a data corrupt error and still be fine a few resets later. AMD B450 Aorus Elite v2 bios date 2/9/23. I have read the forums about AMD’s wonderful integrated 2nd bios feature that I do not believe is causing this issue. I have also disabled auto over clocking features and disabled XMP profiles for the RAM. Also, I realized the usb port that I used prior was getting passed through to my VM and corrupting the usb. Used a different port and has worked better. The usb is a generic 2.0 plugged into a 3.0 socket. Maybe I am missing something? Edited July 20, 2023 by Michigan1112 Quote Link to comment
