https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D256252 Bug ID: 256252 Summary: freebsd-update rollback made system unbootable Product: Base System Version: 13.0-RELEASE Hardware: amd64 OS: Any Status: New Severity: Affects Only Me Priority: --- Component: bin Assignee: bugs@FreeBSD.org Reporter: xistence@0x58.com I am running with ZFS on root using a default install that was made using FreeBSD 12.0-RELEASE a year or two ago. Today I attempted to upgrade to FreeBSD 13.0-RELEASE, after rebooting into = the new kernel network traffic stopped working, so I wanted to roll back the changes FreeBSD update had made: freebsd-update rollback shutdown -r now However after that I got back a mountroot> After some fiddling, I used the following to get back into a bootable state: set currdev=3D"zfs:zroot/ROOT/default:" unload load /boot/kernel.old/kernel load /boot/kernel.old/opensolaris.ko load /boot/kernel.old/zfs.ko boot -s Once in single user mode: zfs set readonly=3Doff zroot zfs mount -a cd /boot cp -pr kernel kernel.13 cp -pr kernel.old kernel.12 rm -rf kernel cp -pr kernel.old kernel shutdown -r now After that my system came back online. When I attempted to load: /boot/kernel/kernel at the loader it would succeed, but would fail when I attempted to load /boot/kernel/opensolaris.ko. Somehow a freebsd-update rollback left me with a broken /boot/kernel. The upgrade was from FreeBSD 12.2-RELEASE-p5 to FreeBSD 13.0-RELEASE-p1. root@Breached:/usr/home/xistence # zpool status pool: zroot state: ONLINE status: Some supported features are not enabled on the pool. The pool can still be used, but some features are unavailable. action: Enable all features using 'zpool upgrade'. Once this is done, the pool may no longer be accessible by software that does not supp= ort the features.
