Description
https://github.com/ceph/ceph/pull/46045
qemu_xfstests is the only job that sporadically fails now: https://pulpito.ceph.com/dis-2022-06-03_20:17:19-rbd:pwl-cache-wip-dis-testing-distro-default-smithi/ 20x qemu_xfstests job: https://pulpito.ceph.com/dis-2022-06-05_10:19:26-rbd:pwl-cache-wip-dis-testing-distro-default-smithi/ 10x all other jobs: https://pulpito.ceph.com/dis-2022-06-05_10:21:14-rbd:pwl-cache-wip-dis-testing-distro-default-smithi/
Breakdown of failures:
086 (e.g. http://qa-proxy.ceph.com/teuthology/dis-2022-06-05_10:19:26-rbd:pwl-cache-wip-dis-testing-distro-default-smithi/6863660) 167 qemu-kvm coredump (https://pulpito.ceph.com/dis-2022-06-05_10:19:26-rbd:pwl-cache-wip-dis-testing-distro-default-smithi/6863685) 199 (http://qa-proxy.ceph.com/teuthology/dis-2022-06-05_10:19:26-rbd:pwl-cache-wip-dis-testing-distro-default-smithi/6863709) 259 (e.g. http://qa-proxy.ceph.com/teuthology/dis-2022-06-05_10:19:26-rbd:pwl-cache-wip-dis-testing-distro-default-smithi/6863682)
259 failure is bogus -- likely a race in the loop driver in the (very!) old kernel baked into the qcow image used by qemu_xfstests or perhaps just a lack of "udevadm settle" calls in the test script.
Need to track down the rest, especially 167 as it appears that it triggered a crash in librbd.
