The command line instead > took this to be the default MB argument for size and so I ended up with a > 102400 TB volume. Deletion was painfully slow (I never used the volume, it > just seemed to spin on CPU for ages going through all the objects it thought it > had) and the rbd rm command was interrupted a few times, but even after > running for two months it still wont complete. > > I still have the volume listed even though it appears to be otherwise gone > from the RADOS view. From what I can see there is only the rbd_header > object remaining - can I just remove that directly or am I risking corrupting > something else by not removing it using rbd rm? > > Cheers, > Adrian > > > [root@ceph-glb-fec-01 ~]# rbd info glebe-sata/oemprd01db_lun00 rbd > image 'oemprd01db_lun00': > size 102400 TB in 26843545600 objects > order 22 (4096 kB objects) > block_name_prefix: rbd_data.8d4ca65a5db37 > format: 2 > features: layering > flags: > [root@ceph-glb-fec-01 ~]# rados ls -p glebe-sata|grep > rbd_data.8d4ca65a5db37 > [root@ceph-glb-fec-01 ~]# rados ls -p glebe-sata|grep 8d4ca65a5db37 > rbd_header.8d4ca65a5db37 > > Confidentiality: This email and any attachments are confidential and may be > subject to copyright, legal or some other professional privilege.
