Kinda old topic, but I ran into the same error, I found a (dirty) workaround
for it.
First, the reason for this is that you are booting a u8 image to restore a u7
or < flasharchive, right?
zpool jumped from version 10 to version 15 with u8. Jumpstart profiles create a
rpool version 15, there is no way to have them create a version 10, that's why
you have this error when rebooting.
Workaround:
1/ Unpack boot archive: /boot/solaris/bin/root_archive unpackmedia /export/u8
/export/mr
2/ Modify the miniroot zpool command to insert a cool (^^) hack:
mv /export/mr/usr/sbin/zpool /export/mr/usr/sbin/zpool.orig
Create the file /export/mr/usr/sbin/zpool, with this content, and make it
executable:
if [ "$1" = "create" ]
then
echo "########################################" | tee /dev/console
echo "# Hacking zpool version" | tee /dev/console
echo "# Parameters: $*" | tee /dev/console
/usr/sbin/zpool.orig `echo "$*" | sed 's/create/create -o version=10/'`
echo "########################################" | tee /dev/console
else
/usr/sbin/zpool.orig $*
fi
Be warned that it is a quick and very dirty hack.
3/ Pack boot archive: /boot/solaris/bin/root_archive packmedia /export/u8
/export/mr
And voilà, now you can jumpstart with ZFS flasharchives.
PS: I also hacked the zfs command, in this way:
if [ "$1" = "receive" ]
then
/usr/sbin/zfs.orig $*
echo "Hacking ZFS mountpoint for rpool" | tee /dev/console
rvol=`/usr/sbin/zfs.orig list|grep "ROOT/"|grep -v @|grep -v var | awk
'{ print $1 }'`
/usr/sbin/zfs.orig set mountpoint=/ $rvol
echo "Set mountpoint=/ for $rvol" | tee /dev/console
else
/usr/sbin/zfs.orig $*
fi
It's useful if you rpool/ROOT has "legacy" for mountpoint instead of "/". In
this case you get an error after the flasharchive extraction during the
Jumpstart. You would get the error "cannot stop the extraction".
Warning this script is not generic, the way to determine the boot volume is
VERY dirty, but works for my environments ^^
Cheers.
