X-Git-Tag: v0.79~72^2~3
X-Git-Url: http://git-server-git.apps.pok.os.sepia.ceph.com/?a=commitdiff_plain;h=7f026ba608691d9b15d0f25bdd2c4f2e79ca037f;p=ceph.git

ceph_test_rados_api_tier: scrub while cache tier is missing clones

Trigger a scrub to verify that we can handle a cache tier that is missing
some clones.  We rely on the test harness to notice the error, and we do
not confirm that the scrub happened.  In practice this is plenty of time,
however.
