Format 1 images don't have any additional features, so there is nothing to enable or disable there. It sounds like you simply mistyped some of your commands. --format is for textual output (json, json-pretty, xml), --image-format is for on-disk format.

See http://lists.opennebula.org/pipermail/ceph-users-ceph.com/2016-May/009635.html for details.

Re: [ceph-users] Map RBD Image with Kernel 3.10.0+10
Figured it out finally!! RBD images must be in format 1, I had to export
the old image and import it as format 1, trying to create format 1 image
fails, it's doesn't like the --image-format command:"
"rbd: the argument for option '--format' is invalid"
Is there a way to create rbd images with format 1 without having to convert
from format 2?
Cheers
Mike

[ceph-users] Map RBD Image with Kernel 3.10.0+10
Hi all,
I need some help yet again... With my cluster backup and running Ceph
10.2.3, I am having problems again mounting an RBD image under Xenserver.
I had this working before I broke everything and started over (previously
on Ceph 10.1), I made sure to set tunables to legacy and disabled
chooseleaf_vary_r which is how I got it working before. Now when I try to
manually mount the image:
echo "192.168.10.39,192.168.10.40,192.168.10.41 name=admin,secret=secret
xen vm0" > /sys/bus/rbd/add
It fails with:
echo: write error: No such device or address
This is different that when I was having problems before getting this
working, something must have changed in 10.2? Below are more details, I
hope it helps.
