[root@c03 bootstrap-osd]# ceph-volume lvm zap /dev/sdf --> Zapping: /dev/sdf --> Unmounting /var/lib/ceph/osd/ceph-19 Running command: umount -v /var/lib/ceph/osd/ceph-19 stderr: umount: /var/lib/ceph/osd/ceph-19 (tmpfs) unmounted Running command: wipefs --all /dev/sdf stderr: wipefs: error: /dev/sdf: probing initialization failed: Device or resource busy --> RuntimeError: command returned non-zero exit status: 1 Pvs / lvs are still there, I guess these are keeping the 'resource busy' _______________________________________________ ceph-users mailing list ceph-users@xxxxxxxxxxxxxx http://lists.ceph.com/listinfo.cgi/ceph-users-ceph.com
