Hi, Recently added one disk in Ceph cluster using "ceph-volume lvm create --data /dev/sdX" but the new OSD didn't start. After some rest of the other nodes OSD service also stopped. So, I restarted all nodes in the cluster now after restart. MON, MDS, MGR and OSD services are not starting. Could find any new logs also after restart it is totally silent in all nodes. Could find some logs in Ceph-volume service. Error in Ceph-volume logs :- [2024-09-15 23:38:15,080][ceph_volume.process][INFO ] stderr Running command: /usr/bin/mount -t tmpfs tmpfs /var/lib/ceph/osd/ceph-5 --> Executable selinuxenabled not in PATH: /usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin Running command: /usr/bin/chown -R ceph:ceph /var/lib/ceph/osd/ceph-5 Running command: /usr/bin/ceph-bluestore-tool --cluster=ceph prime-osd-dir --dev /dev/ceph-33cd42cd-8570-47de-8703-d7cab1acf2ae/osd-block-21968433-bb53-4415-b9e2-fdc36bc4a28e --path /var/lib/ceph/osd/ceph-5 --no-mon-config stderr: failed to read label for /dev/ceph-33cd42cd-8570-47de-8703-d7cab1acf2ae/osd-block-21968433-bb53-4415-b9e2-fdc36bc4a28e: (2) No such file or directory 2024-09-15T23:38:15.059+0530 7fe7767c8100 -1 bluestore(/dev/ceph-33cd42cd-8570-47de-8703-d7cab1acf2ae/osd-block-21968433-bb53-4415-b9e2-fdc36bc4a28e) _read_bdev_label failed to open /dev/ceph-33cd42cd-8570-47de-8703-d7cab1acf2ae/osd-block-21968433-bb53-4415-b9e2-fdc36bc4a28e: (2) No such file or directory --> RuntimeError: command returned non-zero exit status: 1 [2024-09-15 23:38:15,084][ceph_volume.process][INFO ] stderr Running command: /usr/bin/mount -t tmpfs tmpfs /var/lib/ceph/osd/ceph-2 --> Executable selinuxenabled not in PATH: /usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin Running command: /usr/bin/chown -R ceph:ceph /var/lib/ceph/osd/ceph-2 Running command: /usr/bin/ceph-bluestore-tool --cluster=ceph prime-osd-dir --dev /dev/ceph-9a9b8328-66ad-4997-8b9f-5216b56b73e8/osd-block-ac2ae41d-3b77-4bfd-ba5c-737e4266e988 --path /var/lib/ceph/osd/ceph-2 --no-mon-config stderr: failed to read label for /dev/ceph-9a9b8328-66ad-4997-8b9f-5216b56b73e8/osd-block-ac2ae41d-3b77-4bfd-ba5c-737e4266e988: (2) No such file or directory But I could find " /dev/ceph-9a9b8328-66ad-4997-8b9f-5216b56b73e8/osd-block-ac2ae41d-3b77-4bfd-ba5c-737e4266e988" the path valid and listing folder. Not sure how to proceed or where to start any idea or suggestion ?
