Backport "firefly" compatible ceph-deploy from 5.1+

[Denis Klepikov]

We need backport ceph 0.80.X "firefly" from fuel-repository.mirantis.com/fwm/6.0/ to fuel-repository.mirantis.com/fwm/4.X

If we use ceph 0.80.X "firefly" from fuel-repository.mirantis.com/fwm/6.0/ for updating ceph, deployed via fuel 4.0 we reach an error about OrderedDict

Temporary solution -
edit /usr/lib/python2.6/site-packages/ceph_deploy/conf/ceph.py
find
from collections import OrderedDict
and replace with
from ordereddict import OrderedDict
save /usr/lib/python2.6/site-packages/ceph_deploy/conf/ceph.py

Packets list to backport:
ceph-0.80.7
ceph-deploy-1.5.9
ceph-radosgw-0.80.7
libcephfs1-0.80.7
python-ceph-0.80.7
librbd1-0.80.7
librados2-0.80.7
ceph-common-0.80.7

4.x.x series has old Ceph 0.67.x branch. Are we going to introduce a major version update of Ceph in minor MOS release?

[Aleksander Mogylchenko (amogylchenko)]

Also, this seems to be related to ceph-deploy only, not the ceph itself?

[Denis Klepikov (dklepikov)]

Yes, I edit just /usr/lib/python2.6/site-packages/ceph_deploy/conf/ceph.py related to ceph_deploy.
If backporting ceph_deploy will resolve an issue, then we can copy another RPMs from list above into 4.X repository.

[Aleksander Mogylchenko (amogylchenko)]

Then this is about ceph-deploy only, no need to fix something in ceph itself.

[Dmitry Borodaenko (angdraug)]

Backporting ceph-deploy from 5.1.x or later to MOS 4.1.x is risky and can introduce regressions for other users of 4.1.x who do not plan to upgrade their Ceph to 0.80.x. At the same time, as Alexander said, backporting Ceph 0.80.x itself to 4.1.x is definitely too intrusive a change to be considered for a backport at all.

All that being said, if the workaround described in bug description is sufficient to move forward with manual Ceph upgrade, I recommend closing this bug as Won't Fix for 4.1.x, it doesn't seem worth the risk and effort.
