Thanks Jake, however, I need to shrink the image, not delete it as it
contains a live customer image. Is it possible to manually edit the RBD
header to make the necessary adjustment?

Edwin Peer

Hi,
If its the only think in your pool, you could try deleting the
pool instead.
I found that to be faster in my testing; I had created 500TB when
I meant to create 500GB.
Note for the Devs: I would be nice if rbd create/resize would
accept sizes with units (i.e. MB GB TB PB, etc).

Hi there,
I did something stupid while growing an rbd image. I accidentally
mistook the units of the resize command for bytes instead of
megabytes
and grew an rbd image to 650PB instead of 650GB. This all happened
instantaneously enough, but trying to rectify the mistake is
not going
nearly as well.

Resizing image: 1% complete...
</snip>
It took a couple days before it started showing 1% complete
and has
been stuck on 1% for a couple more. At this rate, I should be
able to
shrink the image back to the intended size in about 2016.
Any ideas?

You can just delete the rbd header. See Sebastien's excellent blog:
