Ah, sorry. See src/test/osd/RadosModel.* and src/test/osd/TestRados.cc. It's gotten to be a somewhat kludgy mess, but it's a really valuable stress test for verifying that the osd and librados are behaving properly, especially when combined with failure injection and osd thrashing. I'd like to either create a (less kludgy, I can only hope) seperate version for librados striper, or add a flag to the existing one which causes it to use the striper instead (and only allows ops where it makes sense). libradosstriper should have the same ordering properties for piplined writes as normal librados (right?), so modifying the existing test would probably get us the most coverage for the least effort. -Sam On Wed, Jun 29, 2016 at 8:03 AM, Sebastien Ponce <sebastien.ponce@xxxxxxx> wrote: > Well, I'm not sure what you are exactly looking for : I see now that I > look more carefully that there is a file called ceph_test_rados that > looks like a wrapper around the ceph_test_rados_* tests. > The equivalent does not seem to exist for striper (although the same > wrapper would probably work), but the ceph_test_rados_striper_* tests > do exist. > Should we/I create a wrapper for striper ?
