Re: failed erasure code pool creation after client upgrade

Hi Yuri,

https://github.com/ceph/ceph-qa-suite/commit/3b4442a2014200222764e7fce0cb9c343d97efde

points to 

https://github.com/ceph/ceph/blob/dumpling/qa/workunits/rados/test-upgrade-firefly.sh

however, because the client was upgraded, the ceph_test_rados_api_aio binary being run is the firefly one (only the workunit is pulled from the repository, if I'm not mistaken) and it tries to create the erasure coded pool.

What would probably make sense is to make sure firefly tests are able to run successfully against a dumpling cluster. Or just silently skip tests that can't run on a cluster that does not have the required features ? In any case I can't think of a solution that would run what you want just by juggling with binaries in various branches. But someone else may have an idea, it is entirely possible that I'm missing something simple ;-)

Cheers
