DRBD9, how create a test block device for dd speed test?

[mmenaz]

Hi, I'm newbie of DRBD9 and I'm using with Proxmox 4.1, storage on 2 nodes out of 3.
I would like to follow the "optimizing performance" tests here http://drbd.linbit.com/users-guide-9.0/p-performance.html.
Instead of sacrify a VM disk (i.e. TEST_RESOURCE=vm-100-disk-1), I would love to be able to create a test volume (I'm confused about the terminology used by DRBD, volume? resource? in short, a block device disk like the ones created for VMs) that is under drbd control like a normal disk of a VM on that storage.
Googling and testing I've not been able to create one (and I need to COMPLETELY REMOVE it as well, when test is finished), could you provide me the exact commands for it?
Thanks a lot

To answer myself:
http://drbd.linbit.com/users-guide-9.0/s-dm-new-volume.html
in short I did something like:

# drbdmanage add-resource test1
# drbdmanage add-volume test1 5GB
# drbdmanage deploy-resource test1 2

all the above could be done with a single command (not tested)

drbdmanage add-volume backups 5GB --deploy 2

now I see "test1" as resource on both nodes, and a volume "test1_00"
when I was done, to remove it I simply did

# drbdmanage delete-resource test1

hope will help others
