Hello everyone, I upgraded to Unraid 7.3.1 and my server is currently down. I've done a fair amount of troubleshooting and believe I've hit the known ENOFLASH4 bug, but I haven't been able to resolve it. Hoping someone here can help. SYSTEM DETAILS - License type: Basic (purchased 2022) - Key file: Basic.key present on USB at /boot/config/Basic.key (256 bytes, dated Feb 5 2022) - PHP version: 8.4.21 - Server name: Unraid --- SYMPTOMS - After upgrading to 7.3.1, the WebGUI returns HTTP 500 after login - emhttpd crashes immediately on startup with: emhttpd: Error: (/dev/sda2) not known - All registration fields in var.ini are null (regBuildTime, regTm, regExp, regGUID, regTy, regTo, regDevs, regGen, regCheck, regFILE) - Array will not start, Docker containers are down, shares are inaccessible - Data on array drives is intact and untouched --- USB BOOT DRIVE STATE - Device: /dev/sda (14.9GB USB DISK MODULE) - Partition layout: GPT - sda1: 16MB Microsoft reserved - sda2: 14.9GB FAT32, LABEL="UNRAID", UUID="38D0-4748", PARTUUID="11d1c8bd-fd48-40c5-8651-d6989220ba8e" - /boot mounts correctly to /dev/sda2 - Basic.key and Trial.key are both present in /boot/config/ - No GUID or UUID file exists in /boot/config/ - flash.cfg contains only share/export settings, no device identifier --- PHP ERRORS (also encountered and patched) PHP 8.4 shipped with 7.3.1 introduced stricter type coercion, causing fatal errors in several Dynamix plugin files. I patched these and added fixes to /boot/config/go to persist across reboots: - /usr/local/emhttp/plugins/dynamix/scripts/monitor line 268 - string * int error on mdResyncSize - /usr/local/emhttp/plugins/dynamix/template.php line 59 - date() receiving string "(null)" instead of int for regBuildTime - /usr/local/emhttp/plugins/dynamix.my.servers/include/state.php lines 308/310 - string * int error on regTm and regExp The WebGUI and Registration page now load, but emhttpd still crashes so all reg fields remain null and the array won't start. --- ROOT CAUSE (suspected) The upgrade repartitioned the USB from the old legacy whole-device FAT superfloppy layout to GPT. emhttpd cannot identify the boot device under the new layout and crashes immediately. This matches the ENOFLASH4 bug described in forum topic #198869. --- WHAT I'VE TRIED - Multiple reboots - Manually starting emhttpd - crashes silently every time - Checked /usr/local/sbin/ for a registration or identify utility - none found - Verified key files are present and correct size (256 bytes) - Checked super.dat and all config files for a GUID - none found - Emailed Unraid support at [email protected] - awaiting response --- Any help or guidance would be greatly appreciated. Happy to provide additional diagnostics or run any commands needed. Thank you!
