In addition, you can review what is locking the drive, if anything, with lsof (lsof /dev/...). If you boot a live CD of any distro, you will absolutely wipe the OSD drive with wipefs -a. If you had used a WAL/DB SSD, you need to wipe that too. If you had used LVM for the OSDs you should delete those volume groups, for example: vgs|grep ceph|awk '{print $1}'|xargs -I {} vgremove -y {} We run these procedures often and they always work. -- Alex Gorbachev https://alextelescope.blogspot.com On Sat, Feb 22, 2025 at 4:12 PM Christian Hansen <plomke@hotmail.com> wrote:
So i have battled the last days to reclaim my disk. Basically long story short i installed proxmox cluster with a ceph cluster. I reinstalled the proxmox node and didnt remove the osd as you should trough the gui found out later, i tried a bunch of commands like zap the disk wipe the disk and so on. But whatever i do i cannot wipe the ceph disk and i cant seem to wipe the disk so i can reuse the disk. How do you go about wiping a ceph disk when you reinstalled the original OS that had the disk as the OSD. i tried DBAN, i tried ShredOS i tried Dells wipe disk feature but it says its looked. i tried hirens boot and wiping the disk i tried in diskpart in windows to wipe the disk all things fail and i dont get it. Is there no way to reclaim my disk? Thanks in advance.
