packaging: make infernalis -> jewel upgrade work

[smithfarm]

Attempts to install jewel ceph-common, ceph-mon, ceph-osd, and ceph-base
package over infernalis ceph package fail due to files existing in both.

See comment #4 in the tracker issue for a deeper analysis.

@ktdreyer @BRANTO1 This is untested. Could look it over first? There's probably something obvious I'm missing. When and if you think it's OK, I'll push the branch to gitbuilders and re-run the failing upgrade tests on it.

[ktdreyer]

Did you see #7931 ?

[smithfarm]

@ktdreyer Yes - I don't think it fixes the issue, though. Please read my analysis at http://tracker.ceph.com/issues/15047#note-4

[smithfarm]

We could merge this PR into #7931 if that makes sense.

[ktdreyer]

I think I see what you mean now. I'm ok with this, if it gets teuthology to pass. Are the RPM Conflicts/Obsoletes really necessary?

[smithfarm]

Are the RPM Conflicts/Obsoletes really necessary?

I will prepare a branch without the RPM commit and test that first.

pushed wip-15047-deb-only to gitbuilders

[b-ranto]

I don't think we need the Conflicts line here (and in all the other cases). The Conflicts line would probably only cause problems for us.

As for the Obsoletes line that does make sense, not sure if it is actually necessary though as this might already be covered by the tight 'Requires: <exact_version>' lines.

[smithfarm]

Repushed the RPM patch with the following changes:

1. removed all the Conflicts: lines
2. removed Obsoletes: line from ceph-common
3. added Obsoletes: line to ceph-mds
4. revised the commit message

[smithfarm]

Scheduled a full upgrade/infernalis-x suite on the deb-only integration branch:

smithfarm@teuthology:~/teuthology$ ./virtualenv/bin/teuthology-suite --verbose \
--priority 999 --suite upgrade/infernalis-x --suite-branch jewel --email ncutler@suse.cz \
--ceph wip-15047-deb-only --machine-type vps machine_types/vps.yaml

@yuriw Can you check the teuthology command line in the previous comment? Hopefully I got it right . . .

[smithfarm]

Test completed, logs of failed and dead jobs analyzed. Conclusions:

1. the RPM commit is not needed because the issue does not manifest in RPM
2. the DEB commit fixes this particular issue (failures are due to other issues)

[ktdreyer]

Thanks @smithfarm . We can merge the debian commit, then.

[smithfarm]

RPM commit dropped. Rebased on latest jewel.

[ktdreyer]

thanks for figuring this out!
