Ceph » rbd

The teuthology suit upgrades client host from hammer to jewel and reverts ceph_test_librbd_api to hammer using this procedure:

before upgrade backup hammer ceph_test_librbd_api binary:

cp $(which ceph_test_librbd_api) $TESTDIR/ceph_test_librbd_api

after upgrade restore ceph_test_librbd_api binary:

cp --force $TESTDIR/ceph_test_librbd_api $(which ceph_test_librbd_api)

ceph_test_librbd_api is a dynamically linked binary, so the suit tests client with jewel librbd.

For TestCreateLsDeletePP case it failed because the test created the second image using rbd.create directly (instead of the wrapper that respects RBD_FEATURES env), so the jewel default features from librbd were used.

I guess running hammer ceph_test_librbd_api with jewel librbd is intentional (to run only hammer tests using jewel librbd client)? In this case we need to fix TestCreateLsDeletePP to use create_image_pp() instead of rbd.create().
