May 19, 20197 yr I upgraded my backup server from 6.6.7 to 6.7.0 today resulting in a boot loop after restarting. The server boots to the OS selection screen then reboots after loading bzimage and bzroot. If I select unRAID OS GUI Mode the system boots and everything appears to be running correctly. My first thought was an issue with the update so I recreated the USB key using the unRAID utility and copied the original config folder back onto the drive. I have verified that I am running the latest BIOS and have reset the BIOS settings to optimized defaults. I found two similar posts about this issue with previous versions of unRAID but they seem to end with the user just accepting the workaround of booting into GUI mode by default. My primary server runs nearly identical hardware so i would like to resolve the issue before I move forward with the update. Server Hardware MOBO: Asus P10S-M WS CPU: Intel Xeon E3-1245 V6 RAM: 16GB DDR4 ECC HBA: LSI 9211-8i P20 IT Mode Thanks in advance for any help you can provide.
May 19, 20197 yr Community Expert There have been numerous posts where only gui or non-gui mode would work on a particular hardware/release combination, but I do not think the exact reason why has ever been identified.
May 19, 20197 yr Or to rephrase the above, why worry about it? Zero downside to booting in GUI mode by default (and depending upon how you look at it, there's many upsides) Edited May 19, 20197 yr by Squid
May 20, 20197 yr I think the reason one boot mode works and another doesn't is because of corruption in the non-working bz file. The gui-mode boot requires about 270MB more RAM, hence if RAM is tight and you don't need GUI, then use non-GUI boot mode.
