I upgraded one of our test servers to 8.6 today and wanted to test the filevault2 capabilities. So I got the white paper on it and created the master filevault with key and exported it from keychain. I uploaded it to Casper 8.6 and set up the Encryption Configuration following the white paper.

When I went to test it out using remote I got an error during the test that read:
"Error encrypting disk: Could not encrypt the disk because a required dependency was not found."

I've tried both individual and institutional, both user and manager - no combination seems to work. Has anyone got this to work yet?

Does your test Mac have a working Recovery HD partition? That's required for FileVault 2 to work.

This feature of the Casper Suite is only supported on Mountain Lion, not Lion. That may be what you are seeing here.

Also, is it a RAID'd volume?

Yeah, if you're attempting this on a 10.7 client, it won't work. Apple added some under the hood tools to make this possible with Mountain Lion that are not there in Lino.

I have have only tested individual and institutional and just individual, I was able to get them working... I didn't have to do anything special just be sure your Recovery HD partition is there.

Also the only way I could trigger the FDE is with a restart from the GUI, no CLI or casper restart enable the password box.

This article made me 100% smarter about how FV2 works in X.8 https://derflounder.wordpress.com/2012/07/25/using-fdesetup-with-mountain-lions-filevault-2/

The machine doesn't have a recovery HD Partition. Any easy way to create one? I can blow the whole machine if needed since it's a test. But I know most of our machines don't have the recovery HD Partition.

So in thinking for the future, should I try to capture the recovery HD partition as an image and add it to our images?

You can build an installer package to install a Recovery HD partition. The procedure for Lion is posted here:

This process should also work for Mountain Lion, but I haven't tested it yet.
