DDVE on AWS Object Storage Creation Fails

I'm attempting to deploy DDVE on AWS and am trying to create an Object Storage filesystem on S3. I've provisioned a couple of metadata disks, but every time I go to create the filesystem I get the following error:

# filesys create
A filesystem of approximate size 96.13 TiB will be created.

** The current metadata capacity is 2.00 TiB.
To reach the filesystem capacity of 96.00 TiB, the metadata capacity needs to be 10.00 TiB
Do you want to continue? (yes|no) [yes]: yes

ok, continuing.

This will take 5 - 10 minutes.

Error (1) creating filesystem. Log stored in /ddr/var/log/debug/create.11347-762.log

If I look at the log file mentioned, I get the oh-so-terribly-helpful content:

Configuring 'ddr'


Cannot create the NVRAM file: /db/DDVE_nv does not exist
Create appropriate device nodes and rerun /ddr/bin/mkddr

I've attempted to look up that particular error message, and nothing turns up.

Any hints would be appreciated. I've updated to DDOS 7.11, so latest & greatest, there.
