[sheepdog-users] 'dog vdi create' and specific size

Hi, I need to create a vdi with the exact same size of a logical volume (in
general, of a block device).

lvdisplay --unit K /dev/vg00/test | grep 'LV Size'
  LV Size                524288,00 kB

dog vdi list -r test_mirror
= test_mirror 0 536870912 0 0 1391435637 fc8681 2:1

As you can see, device size doesn't match.
Is there a specific reason?
Is it possible to get the exact size I require?

Nonetheless I can't use Byte unit to create a vdi.
In the above example, LV Size is multiple of 1024 but, in other cases, I
need to specify a size that is not a multiple of 1024.


lvdisplay --unit K /dev/ssd/win7office  | grep 'LV Size'
  LV Size                54760833,02 kB

It would be cool to be able to use Byte as unit

lvdisplay --unit B /dev/ssd/win7office  | grep 'LV Size'
  LV Size                54760833024 B

dog vdi create win7office_mirror 54760833024B

'You may use k, M, G, T or P suffixes for kilobytes, megabytes, gigabytes,
terabytes and petabytes.'

Thank you.
