>Description:
After creating a geli encrypted provider using:
geli init -b -v -a hmac/sha512 -e aes-cbc -l 256 -s 4096 /dev/ad0p1
geli attach /dev/ad0p1

I am unable to partition the resulting provider with a GPT scheme with gpart.  The BSD scheme works just fine, which is the workaround I am using.

The error is as follows:
#gpart create -s GPT ad0p1.eli
gpart: provider: Device not configured

But, when I use a BSD scheme:
#gpart create -s GPT ad0p1.eli
ad0p1.eli created
>How-To-Repeat:
geli init -b -v -a hmac/sha512 -e aes-cbc -l 256 -s 4096 /dev/ad0p1
geli attach /dev/ad0p1
gpart create -s GPT ad0p1.eli
>Fix:
Not a real fix, but using BSD as the scheme allows you to at least partition the provider.
