I have a couple of ZFS boxes I want to upgrade from RELENG_10 to
RELENG_11 and before doing it, I wanted to clone them into a VM to test
out the upgrades. In the past, this was easy enough using actual
hardware. However, I cant seem to get it going in a VM. I tried doing
the following steps
truncate -s 999G server.img
mdconfig -f server.img
gpart create -s gpt md0
gpart add -s 222 -t freebsd-boot md0
gpart add -t freebsd-zfs md0
gpart bootcode -b /tmp/pmbr -p /tmp/gptzfsboot -i 1 md0 #these files
are taken from the RELENG_10 image
zpool create -f -o altroot=/mnt2 -O canmount=off -m none zroot /dev/md0p2
gzcat zroot.0.gz | zfs recv -vF zroot
zpool import -f -o altroot=/mnt2 zroot
zpool set bootfs=zroot/ROOT/default zroot
zpool export zroot
mdconfig -d -u0
Then I imported the file server.img into a KVM instance.
and everything starts to boot fine, but then fails with
mounting from zfs:zroot/ROOT/default failed with error 45
if I hit ? it shows
List of GEOM managed disk devices:
vtbd0p2 vtbd0p1 vtbd0
mountroot>
if I try
mountroot> zfs:zroot
Trying to mount root from zfs:zroot [] ...
Mounting from zfs:zroot failed with error 45
same with zfs:zroot/ROOT/default
error 45.
