Re: [openstack-dev] [kolla] Ubuntu jobs failed on pike branch due to package dependency

2018-03-06 Thread Jeffrey Zhang 
Here is what i tried[0].

- pin ceph version in ceph-* container to Jewel.
- the clients (nova/gnocchi/cinder) container use ceph Luminous.

I made some test locally with a env: nova + glance + gnocchi + ceph, seems
it works.

I'm for option 1 definitely. accidental ceph upgrade during routine
minor version upgrade is something we don't want. We will need big
warning about this version mismatch in release notes.

Re: [openstack-dev] [kolla] Ubuntu jobs failed on pike branch due to package dependency

2018-02-26 Thread Eduardo Gonzalez 
I prefer option 1, breaking stable policy is not good for users. They will
be forced to upgrade a major ceph version during a minor upgrade, which is
not good and not excepted to be done ever.
