disk encryption with geli

[Stefan Miklosovic]

hi all

i am going to encrypt my /home directory
which is mounted in /etc/fstab like

/dev/ad0s2f             /home           ufs         rw,noatime
2       2

I did like is wrote in
http://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/disks-encrypting.html
everything looks good. ad0s2f.eli appears in /dev and so on. I can mount it,
umount and so.

but after reboot, I am dropped to single user mode because of en error
message which says that
there is an inconsistency at /dev/ad0s2f

do i have to encrypt whole ad0 or it is possible to encrypt only my /home?
