A while back I attempted to create an RBD volume manually - intending it to be
an exact size of another LUN around 100G. 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
