On one of my VMs that I upgraded from RELENG_13 to RELENG_14, I forgot
to update the boot loader so now at bootup, I have
ZFS: unsupported feature: com.klarasystems:vdev_zaps_v2
Can't find /boot/zfsloader
What is the best way to recover from this ? Its a raw vm image. gpart is
p1=freebsd-boot, p2=freebsd-swap,p3=freebsd-zfs
I was thinking perhaps start up a second vm thats RELENG_14, mdconfig
the image, and then what do I need to do ? Just
gpart bootcode -b /boot/pmbr -p /boot/gptzfsboot -i 1 md0 ?
Yes -- basically you fix this by booting from some other media, and
copying in the updated RELENG_14 bootblocks to your disk image. Very
much analogously to how you'ld fix it on physical hardware.
You should be able to boot your VM from the installation memstick image
by loading it into the virtual CD drive -- that's probably the simplest.
