is there a way to see how much data is allocated as opposed to just
what was used? for example, this 20gig image is only taking up 8gigs.
id like to see a df with the full allocation of images.
root@ceph1:~# rbd --image vm-101-disk-1 info
rbd image 'vm-101-disk-1':
size 20480 MB in 5120 objects
order 22 (4096 kB objects)
block_name_prefix: rbd_data.105c2ae8944a
format: 2
features: layering
root@ceph1:~# ceph df
GLOBAL:
SIZE AVAIL RAW USED %RAW USED
66850G 66842G 8136M 0.01
POOLS:
