You are running ZFS version 4 while the default is 5 on 9.0-RELEASE ---> Assuming your pool is called zroot --->This is the way to update your zpool.cache: <--- Boot with 9.0-RELEASE and proceed with: #zpool import -o altroot=3D/mnt -o cachefile=3D/var/tmp/zpool.cache zroot #zfs set mountpoint=3D/mnt zroot #zfs set mountpoint=3D/mnt/usr zroot/usr #zfs set mountpoint=3D/mnt/var zroot/var #zfs set mountpoint=3D/mnt/tmp zroot/tmp ## Ignore any warnings## Now export the pool: #zpool export -f zroot Import the pool back and update the zpool.cache: #zpool import -o cachefile=3D/var/tmp/zpool.cache zroot #cp /var/tmp/zpool.cache /mnt/boot/zfs/zpool.cache Make sure that bootfs is set correctly: #zpool set bootfs=3Dzroot zroot Now, unmount any ZFS datasets #zfs umount -af And fix mountpoints: #zfs set mountpoint=3Dlegacy zroot #zfs set mountpoint=3D/tmp zroot/tmp #zfs set mountpoint=3D/usr zroot/usr #zfs set mountpoint=3D/var zroot/var That should be enough to update your zpool.cache If this still doesn't work then you can upgrade your ZFS version to 5. Make sure you have backups first!!! Before unmounting your datasets issue a: zfs upgrade -a --=20 George Kontostanos Aicom telecoms ltd http://www.aisecure.net
