If it creates it, should also remove it. Ceph-disk prepare did not create it, so it is logical if it does not remove it. ceph-volume however creates it, thus should remove it. -----Original Message----- From: David Turner [mailto:drakonstein@xxxxxxxxx] Sent: zaterdag 2 juni 2018 23:36 To: Marc Roos Cc: ceph-users Subject: Re: Bug? ceph-volume zap not working Ceph-disk didn't remove an osd from the cluster either. That has never been a thing for ceph-disk or ceph-volume. There are other commands for that.

What we are ended up using is: ceph-volume lvm zap /dev/sda --destroy This takes care of destroying Pvs and Lvs (as the documentation says).
