I need to import about 100 different VMDK data volumes into new Cinder volumes. These are not bootable volumes. Is there a way to this without having to first upload each one of them into Glance then creating cinder volumes with glance image as the source?

If you are using Ceph you can directly import the vmdk image. rbd import --image-format 2 image.vmdk volumes/volume-63472da4-a11d-4dd0-90a8-c741c0a87d85

I was unaware of that. I dont often have to work with vmdk's. Thank you for the tip!

I can think of a few ways this can be done, they are a little bit dirty though. It will also depend on your backend.

What are you using for cinder as a backend? Answered: Ceph

You could use a script to create a cinder volume of the appropriate size and name.

Then simply dd the logical volume inside the vmdk to the newly create ceph rbd. This isn't ideal since it will write out every bit, so you would need to do some sort of sparse copy to only get the used data. There are a few ways to do that with some cloning tools but there may be a VMDK method as well. That would work best.

Thanks for the response. Ceph (firefly) cluster is configured for Cinder backend.
