I am to silly to mount a zpool while boot

Hello all,

a few of the things I already had done. But the real problem is I think 
that the pool doesn't get imported automatically. I read that ZFS 
searches in special directories when it tries to import. So is there a 
way to set an option which says that it should search in /dev? I always 
have to do this after reboot:

zpool import -d /dev tank

Than tank (pool) gets mounted at /tank and the zvol tank/home gets 
mounted on /home.

So I think that the import of the zpool fails. I have set 
zfs_enable="YES" in /etc/rc.conf also zfs_load=YES as boot parameter 
which gets shown in kenv and commented out the fstab entry. So I read 
that the import normally should work automatically when the module is 
loaded and zfs is enabled but I think the fact that my pool is located 
on /dev/xbd2 is the problem.

Best Regards
