Post #3816195

A couple of days ago, few hours before leaving home for a four days trip I decide to upgrade one of my home servers to FreeBSD 15.1. Nothing difficult. After upgrade the machine start rebooting in a loop. I pick up my serial cable and see the boot process crash when mounting ZFS panic: zfs(panic): zfs: rt={spa=zroot vdev_guid=546977716602668702 ms_id=9 ms_freed}: adding segment (offset=2431c0000 size=1000) overlapping with existing one (offset=2431c0000 size=1000) 😬 that's terrible. I relay on this machine to access my nextcloud where all my trip tickets are stored. Hopefully ZFS saves my day! I was able to boot back to the previous snapshot, and smoothly restore the service, but I probably need to start thinking in a replacement for this machine.... #FreeBSD #ZFS
