Re: [ceph-users] Reinstall everything
I used ceph-deploy to purge the data. However it didn't remove LVM. I'm gonna to see the "lvm" part. Seems new, i used always disk instead since now.

Not sure if ceph-deploy has similar functionality, but executing ‘ceph-volume lvm zap --destroy’ on target machine would have removed lvm mapping.

I solved by myself. I' writing here my findings to save some working hours to others. Sound strange that nobody knew this. The issue is that data is purged but LVM partition are leaved in place. This means that you need to manually remove. I just reinstalled the whole OS and on the data disks there are still LVM partition named "ceph-*". These partition are ACTIVE by default.
