geli device istgt

[Johannes Mäulen]

Hi there,
I'm new here, "Hello" :). Hopefully it's the right mailing list...
I've setup a Freebsd 9.0-RELEASE machine to handle my storage devices.
I'd like to "share" encrypted partitions via iscsi. But, I'd like to take the encryption take place on the iscsi-target(-machine). The machine is equipped with a aes-ni capable cpu, which I'd like to use. I set up a geli device, but whenever I try to use it as target I get errors like:

/usr/local/etc/rc.d/istgt start
Starting istgt.

istgt.c:2799:main: ***ERROR*** istgt_lu_init() failed
/usr/local/etc/rc.d/istgt: WARNING: failed to start istgt

Could somebody help me with that?
If I try to start istgt with an unencrypted partition everything works as expected.

Kind regards

Johannes
