Carp kernel module missing from FreeNAS?

[Brent Clark]

Guys

Im looking to have a failover for my FreeNAS systsem.

Im folllowing this, example (
http://qq929962616.72pines.com/2012/03/configure-highly-available-storage-on-freenas/
), but is doesnt look like the Carp module is available.

If that is true, anyone know how I can go about adding / enabling carp
on FreeNAS.

Someone made a suggestion of:

FreeNAS uses a standard FreeBSD Kernel, so you can simply download the
module from the FreeBSD FTP site and it will work. You have to have
the right version however.

How can or woulld I go about that?

Your help would be most appreciated.

Regards
