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.
Provisioning storage...
########################################### [100%]
Initializing filesystem...
########################################### [5%]
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.

Thanks for the response, Barry - we did finally get this working. Yes, this is a DDVE deployment in AWS EC2, using Object Storage as the filesystem. The issue was that we had not attached a 10GB disk at /dev/sdb for the NVRAM disk, and this was causing the not-terribly-helpful error message mentioned above. Once we attached that, we were able to proceed.

was this a DDVE deployment through AWS marketplace? Did it ever work? Or was filesystem not working from the start? But apparently a DDOS upgrade was successful?
As I see 96TB being mentioned, you are using managed disk as storage or rather ATOS (active tier object storage)? The limit for managed disk in cloud being 96TB whereas with object storage one can go as far as 256TB.
Any alerts being posted by DDOS? Like nvmram related or unsupported virtual hardware configuration?

So you didn't perform the Cloud Formation deployment through the marketplace therefor?

So you did a manual deployment from the AWS console and forgot the step 5. to "Add the NVRAM disk and metadata disks (...)" as stated in https://www.dell.com/support/manuals/en-us/dd-virtual-edition/dd_p_ddve-7.11-aws_ig/deploying-ddve-manually-from-the-aws-console?guid=guid-d132b1e8-3c6b-40d3-ba2f-70827dc789f2&lang=en-us ?
