Hi, I really like the behavior of ceph to auto-manage block devices. But I get ceph status warnings if I map an image to a /dev/rbd Some log output: Aug 29 11:57:34 hvs002 bash[465970]: Non-zero exit code 2 from /usr/bin/docker run --rm --ipc=host --stop-signal=SIGTERM --net=host --entrypoint /usr/sbin/ceph-volume --privileged --group-add=disk --init -e CONTAINER_IMAGE=quay.io/ceph/ceph@sha256:43f6e905f3e34abe4adbc9042b9d6f6b625dee8fa8d93c2bae53fa9b61c3df1a -e NODE_NAME=hvs002 -e CEPH_USE_RANDOM_NONCE=1 -e CEPH_VOLUME_OSDSPEC_AFFINITY=all-available-devices -e CEPH_VOLUME_SKIP_RESTORECON=yes -e CEPH_VOLUME_DEBUG=1 -v /var/run/ceph/dd4b0610-b4d2-11ec-bb58-d1b32ae31585:/var/run/ceph:z -v /var/log/ceph/dd4b0610-b4d2-11ec-bb58-d1b32ae31585:/var/log/ceph:z -v /var/lib/ceph/dd4b0610-b4d2-11ec-bb58-d1b32ae31585/crash:/var/lib/ceph/crash:z -v /dev:/dev -v /run/udev:/run/udev -v /sys:/sys -v /run/lvm:/run/lvm -v /run/lock/lvm:/run/lock/lvm -v /:/rootfs -v /tmp/ceph-tmpke1ihnc_:/etc/ceph/ceph.conf:z -v /tmp/ceph-tmpaqbxw8ga:/var/lib/ceph/bootstrap-osd/ceph.keyring:z quay.io/ceph/ceph@sha256:43f6e905f3e34abe4adbc9042b9d6f6b625dee8fa8d93c2bae 53fa9b61c3df1a lvm batch --no-auto /dev/rbd0 --yes --no-systemd Aug 29 11:57:34 hvs002 bash[465970]: /usr/bin/docker: stderr stderr: lsblk: /dev/rbd0: not a block device Aug 29 11:57:34 hvs002 bash[465970]: cluster 2022-08-29T09:57:33.973654+0000 mon.hvs001 (mon.0) 34133 : cluster [WRN] Health check failed: Failed to apply 1 service(s): osd.all-available-devices (CEPHADM_APPLY_SPEC_FAIL) If I map a image to a rdb, the automanage feature want to add it as an osd. It fails (as it apparently isn't detected as a block device), so I guess my images are untouched, but still I worry because I can't find a lot of information about these warnings. Do I risk a conflict between my operations on a mapped rbd image/device? Wil at some point ceph alter my image unintentionally? Do I risk ceph to add such an image as an osd? I can disable the managed feature of the osd-management, but then I lose automatic functions of ceph. Is there a way to tell ceph to exclude /dev/rdb* devices from the autodetect/automanage?
