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 ?
A little easier than I though. I just grabbed the 2 files from a
RELENG_14 image and put them in /tmp on my nfs server where the raw vm
image is. Then
mdconfig -f problem-vm-image.raw
gpart bootcode -b /tmp/pmbr -p /tmp/gptzfsboot -i 1 md0
mdconfig -d -u 0
and its up and running again
