Hi Cephers, I got problem removing /var/lib/ceph/osd/ceph-53 dir which was used by OSD.53 that I have removed.
The way that I remove the OSD: 1. ceph osd out 53 2. sudo service ceph stop osd.53 3. ceph osd crush remove osd.53 4. ceph auth del osd.53 5. ceph osd rm 53 6. sudo umount /var/lib/ceph/osd/ceph-53 and then I try to 'sudo rm -rf /var/lib/ceph/osd/ceph-53' but got a following response: sudo rm -rf /var/lib/ceph/osd/ceph-53 rm: cannot remove '/var/lib/ceph/osd/ceph-53': Device or resource busy I use 'fuser -m' to check and saw following results: sudo fuser -m /var/lib/ceph/osd/ceph-53 /var/lib/ceph/osd/ceph-53: 1rce 2rc 3rc 5rc 8rc 9rc 10rc 11rc 12rc 13rc 14rc 15rc 16rc 17rc 18rc 19rc 20rc
