The -devel package was removed from this commit last week:

https://github.com/ceph/ceph/commit/c341c52984ca7c7b814b1adc269b7fb8d4c57a29#diff-ca40628478ff1274b73dcd40c384e7f0

So it looks like for newer packages we no longer want to install using the -devel package. Maybe an old PACKAGES['ceph']['rpm'] list that it tries first and fallbacks to the new one or vice-versa? Not really sure how we are handling these new splits and removal of packages in teuthology itself.

Not sure how this is handled since so many packages are obsoleting it if via yum you are telling it to install the obseleted package (via yum calculating stuff on dependencies) I can play around with this manually a bit to see what our options are to but its not gitbuilder or infrastructure related.

Talking to Ken it looks like the obsoletes should handle this. I will definitely do some manual testing as we want this fixed ASAP.

From playing around manually with this, "yum install ceph-devel-0.92" fails, whereas "yum install ceph-devel" succeeds.

Ok so appending the version is what is causing the problem. I think we were doing that to insure it was getting the right version from the right repo? Didn't we recently make some changes to the priorities so versions in epel and stuff would not get considered? Maybe we don't actually need to be doing that anymore?

If it's done to override EPEL, I wonder if that technique of appending the version number was done long before we started using yum's priorities plugin, because the yum priorities plugin should allow you to basically ignore what's going on downstream in favor of what is in gitbuilder (or ceph.com, or whatever).

Another hunch I had was that the version number might be present here to permit Teuthology to test upgrades from one version of Ceph to another? Is that the case? (total newbie-to-teuthology question :)

I actually don't think we need the version appended anymore. I think the change to the priorities config file to check_obsletes was probably the correct fix and we were getting around it specifying the version number. Testing how teuthology changes the ceph.repo file and manually testing with older versions (even dumpling) without appending versions with the /etc/yum.pluginconf.d/priorities.conf it now appears to be getting the correct version from the repo we specified and before we were probably doing a hack so I think we can safely remove that appended version now. I will make a wip branch and have yuri do a run.

Sounds good. Thanks for looking into this!

Sandon, I can take the teuthology work on this if you'd like. Thanks for looking into this!
