RBD image feature set mismatch

[gator1]

Hi,
Great work.

I followed your instructions (only to change names of the servers to mon-1--3 and osd-1--3).
I got the status as HEALTH_OK with three osd in and up.

When I tried to map a rbd I got this.

Do you have the same issue? Do you know how to fix it?

In the general term, how do you manage virtualbox ubuntu VM to manage drives?

vagrant@ceph-client:$ sudo rbd create foo --size 4096 -m mon-1
vagrant@ceph-client:$ sudo rbd map foo --pool rbd --name client.admin -m mon-1
rbd: sysfs write failed
RBD image feature set mismatch. You can disable features unsupported by the kernel with "rbd feature disable".
In some cases useful info is found in syslog - try "dmesg | tail" or so.
rbd: map failed: (6) No such device or address

need to do this
rbd create --size 4096 docker_test --image-feature layering
