Ceph volume cannot be attached/created in case of different cinder rbd_user and pool name

[Andrey Grebennikov]

If "rbd_user" options in the config files "nova.conf" on the compute node and "cinder.conf" on the controller is not equal to "rbd_pool", ceph volumes cannot be created or attached to the instance.
The reason is that env variable "CEPH_ARGS" takes the priority in case it is defined, but there in the manifests
cinder/manifests/volume/ceph.pp
ceph/manifests/nova_compute.pp
it is defined as "--id ${rbd_pool}'", but it has to be "--id ${user}'" (for nova_compute.pp) and "--id ${rbd_user}'" (for ceph.pp)
Or it can be just excluded from the manifests at all (probably)

[Dmitry Borodaenko (angdraug)]

You're right, CEPH_ARGS was only necessary with Grizzly. Starting with Havana, Cinder and Nova consistently use ceph_args() method to add "--id <rbd_user>" parameter to all invokations of rbd and ceph commands, and Glance doesn't use these commands at all.

    remove CEPH_ARGS from Nova and Cinder

    Now that Nova and Cinder consistently pass --id option when executing rbd and
    ceph commands, it's no longer necessary to set CEPH_ARGS environment variable
    in the init scripts for Nova and Cinder services.
