Hi, 
I want to encrypt some disk on my server with Zfs encryption property but it is 
not available.

Are there anybody have got an experience about this?

Sizes are specified in bytes with standard units such as K, M, G, etc.

User-defined properties can be specified by using a name containing a colon (:).

The {user|group}{used|quota}@ properties must be appended with
a user or group specifier of one of these forms:
    POSIX name      (eg: "matt")
    POSIX id        (eg: "126829")
    SMB name@domain (eg: "matt@sun")
    SMB SID         (eg: "S-1-234-567-89")

How can I use or add encryption property to FreeBsd 8.3?
