I cannot recreate that "rbd feature disable" error using a master branch build

Fio has a direct RBD engine which uses librbd. I've just had a quick look at
the code and I can't see an option in the latest fio to specify da

I cannot recreate that "rbd feature disable" error using a master
branch build from yesterday. Can you still reproduce this where your
rbd CLI can create a data pool image but cannot access the image
afterwards?
As for how to run against a librbd-backed client, it depends on what

Thanks Nick,
I have not tried using rbd-nbd, I will give it a try. Rbd mapping is failing
for the image which was created with -data-pool option, so I can't
run fio or any IO on it.

The kernel krbd driver doesn't support the new RBD data pool feature.
This will only function using librbd-backed clients.
The error that you are seeing with "rbd feature disable" is unexpected
-- any chance your OSDs are old and don't support the feature?

Hi Aravind,
I've also seen this merge on Monday and tried to create a RBD on an ecpool and
also failed. Although I ended up with all my OSD's
crashing and refusing to restart. I'm going to rebuild the cluster and try
again.
Have you tried using the rbd-nbd driver or benchmarking directly
