Hi, If you want to remove the ceph lv partition you can try : dmsetup remove ceph--dfaa321c--b04d--48e8--b78b--7c39436be0e5-osd--block--36473043--6d2c--4c7a--b61c--b057e83f0169 ________________________________ De : Steven Vacaroaia <stef97@gmail.com> Envoyé : mercredi 3 septembre 2025 15:11:48 À : ceph-users Objet : [ceph-users] squid 19.2.2 - drive in use but ceph is seeing it as "available" Hi, I would appreciate some guidance here I am trying to reconfigure OSD to put DB/WAL on NVME so I "out" and "ceph osd rm" them ( because they were automatically configured and I did not "set-unamage" them properly ) then "wipefs -af " them Now CEPH is seeing drives available for deploying OSD on but it fails doing it due to "device or resource busy" Attempting to destroy and zap it fails due to "device or resource busy" even after I "wipefs -af /dev/sdaa" it this is what it is on it ( output of lsblk) sdaa 18.2T disk └─ceph--dfaa321c--b04d--48e8--b78b--7c39436be0e5-osd--block--36473043--6d2c--4c7a--b61c--b057e83f0169 18.2T lvm lvs,vgs does not find any logical disks /volume cephadm ceph-volume inventory is seeing the disks as "available = True" cephadm ceph-volume lvm list is NOT finding any LVM on /dev/sdaa docker ps -a does not show any "left over" OSD docker There is a reference ( block link) to the /dev/ceph--dfaa321c--b04d--48e8--b78b--7c39436be0e5-osd--block--36473043--6d2c--4c7a--b61c--b057e83f016 in /var/lib/cephFSID/removed/osd.NUMER_DATE How can I 'clean up' the disk ?
