Rafał Stępień Posted April 15, 2024 Posted April 15, 2024 Hi, I've been on Unraid 6.12.8 and few days from know my server crashed. It was on but WebUI wasn't loading, SSH wasn't working, I haven't even seen server on my router. So I did hard reset. From this moment I can't properly reboot my server. If done by WebUI it counts indefinitely but when I open WebUI in new window there is text on the bottom "Array Stopping Unmounting disks..." and one of the cores is on constatnt 100% load. Reboot from SSH by reboot or shutdown command dosen't work either. Only this command works and after reboot there is unclean shutdown notification: echo b >/proc/sysrq-trigger I've updated to Unraid 6.12.10 and problem still occurs. I've tried swtich macvlan to ipvlan. Still nothing. I've enabled mirroring syslog to sdcard and here is the diagnostics. unraid-diagnostics-20240415-2003.zip Quote
JorgeB Posted April 16, 2024 Posted April 16, 2024 The current diags don't show the pool mounting, and that pool was also apparently the problem before, does it still mount? Quote
Rafał Stępień Posted April 16, 2024 Author Posted April 16, 2024 Yes, after forced reboot pool mounts successfully and I can use them normally. Quote
Rafał Stępień Posted April 16, 2024 Author Posted April 16, 2024 Now tried to shutdown from WebUI and I connected video output. On screen last output was "Generating diagnostics..." and It stayed there for couple of minutes before I forced the shutdown by switch. unraid-diagnostics-20240416-1729.zip Quote
Rafał Stępień Posted April 16, 2024 Author Posted April 16, 2024 When I run in safe mode and tried to start array manually I saw almoast immediately this output in terminal: kernel:PANIC at range_tree.c:436:range_tree_remove_impl() Rebooting in safe mode with no dockers and VMs is also stuck on unmouting and gathering diagnostics.

Solution JorgeB Posted April 16, 2024 Solution Posted April 16, 2024 The zfs pool is corrupt, you should backup and re-format, see if it mounts read-only without panicking, you can then backup. Reboot the server, don't start the array, and type: zpool import -o readonly=on cache If OK, start the array, cache will show unmountable in the WebGUI, but the data will be under /mnt/cache, backup and then re-format.
