We can create a consistency group:
  openstack consistency group create --volume-type b9f67298-cf68-4cb2-bed2-c806c5f83487 fsc-consgroup


Bug 1: but adding volumes is not working:
  openstack consistency group add volume c3f49ef0-601e-4558-a75a-9b758304ce3b b48752e3-641f-4a49-a892-6cb54ab6b74d c0022411-59a4-4c7c-9474-c7ea8ccc7691 0f4c6493-dbe2-4f75-8e37-5541a267e3f2 
  =>   Invalid volume: Volume is not local to this node. (HTTP 400) (Request-ID: req-7f67934a-5835-40ef-b25c-12591fd79f85)


Bug 2: deleting consistency group is also not working (silently failing):
  openstack consistency group delete c3f49ef0-601e-4558-a75a-9b758304ce3b
  => AttributeError: 'RBDDriver' object has no attribute 'delete_consistencygroup'
  See details below.
  Using the --force option makes no difference and the consistency group is not deleted.
  

Do you think this is a bug or a configuration issue?

Thank you in advance.

Cheers

Francois
