Hi, We had a physical drive malfunction in one of our Ceph OSD hosts managed by cephadm (Ceph 16.2.14). I have removed the drive from the system, and the kernel no longer sees it: ceph03 ~]# ls -al /dev/sde ls: cannot access '/dev/sde': No such file or directory I have removed the corresponding OSD from cephadm, crush map, etc. For all intents and purposes that OSD and its block device no longer exist: root@ceph01:/# ceph orch ps | grep osd.26 root@ceph01:/# ceph osd tree| grep 26 root@ceph01:/# ceph orch device ls | grep -E "ceph03.*sde" None of the above commands return anything. Cephadm correctly sees 8 remaining OSDs on the host: root@ceph01:/# ceph orch ls | grep ceph03_c osd.ceph03_combined_osd 8 33s ago 2y ceph03 Unfortunately, cephadm appears to be trying to apply a spec to host ceph03 including the disk that is now missing: RuntimeError: Failed command: /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@sha256:843f112990e6489362c625229c3ea3d90b8734bd5e14e0aeaf89942fbb980a8b -e NODE_NAME=ceph03 -e CEPH_USE_RANDOM_NONCE=1 -e CEPH_VOLUME_OSDSPEC_AFFINITY=ceph03_combined_osd -e CEPH_VOLUME_SKIP_RESTORECON=yes -e CEPH_VOLUME_DEBUG=1 -v /var/run/ceph/3f50555a-ae2a-11eb-a2fc-ffde44714d86:/var/run/ceph:z -v /var/log/ceph/3f50555a-ae2a-11eb-a2fc-ffde44714d86:/var/log/ceph:z -v /var/lib/ceph/3f50555a-ae2a-11eb-a2fc-ffde44714d86/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-tmpc7b33pf0:/etc/ceph/ceph.conf:z -v /tmp/ceph-tmpq45nkmd6:/var/lib/ceph/bootstrap-osd/ceph.keyring:z quay.io/ceph/ceph@sha256:843f112990e6489362c625229c3ea3d90b8734bd5e14e0aeaf89942fbb980a8b lvm batch --no-auto /dev/sda /dev/sdb /dev/sdc /dev/sdd /dev/sde /dev/sdf /dev/sdg /dev/sdh /dev/sdi --db-devices /dev/nvme0n1 /dev/nvme1n1 --yes --no-systemd Note that `lvm batch` includes the missing drive, /dev/sde. This fails because the drive no longer exists. Other than this cephadm ceph-volume thingy, the cluster is healthy.How can I tell cephadm that it should stop trying to use /dev/sde, which no longer exists, without affecting other OSDs on the host? I would very much appreciate any advice or pointers. Best regards, Zakhar
