Unfortunately error 5 isn't very helpful as that's just EIO :(
When booted from the old kernel try moving out the cache file e.g.
mv /boot/zfs/zpool.cache /boot/zfs/zpool.cache.old
If for some reason your cache file and your disks are out of sync that
might help.
Also ensure your loading zfs in /etc/rc.conf
zfs_enable="YES"
Check you don't have anything zfs custom in /boot/loader.conf
You should just have the two zfs related lines such as:
zfs_load="YES"
vfs.root.mountfrom="zfs:tank/root"
Your pool layout does look a little odd from your zpool get all as
bootfs seems to be set to just "tank" is that correct as its quite
none
standard? If not and your root is tank/root then that might also be your
issue.
Next up there should be no need for mountpoint legacy / should do just fine.
If you do have a single partition install you might want to consider
switching to something more standard which looks something like:
NAME USED AVAIL REFER MOUNTPOINT
tank 853G 292G 46.5K none
tank/root 21.6G 292G 21.3G /
tank/root/tmp 11.2M 292G 11.2M /tmp
tank/root/var 270M 292G 270M /var
Oh and ensure your boot loader has been updated:
gpart bootcode -b /boot/pmbr -p /boot/gptzfsboot -i 1 ada0
gpart bootcode -b /boot/pmbr -p /boot/gptzfsboot -i 1 ada1
Hope this helps.
Regards
Steve
