ceph rbd

First of, a bit more patience please, things are slower, especially on the weekends :)

What you are showing doesn´t really make any sense. The first screenshot is of an image stored in an RBD pool. The second one shows the summary of a storage of the type RBD. Not of the image.

Can you please post the contents of your /etc/pve/storage.cfg inside of [CODE][/CODE] tags?
Okay, so my suspicion:

The pool "rbdpool" in the external Ceph cluster, only has 30 GiB of space available. The disk images are thin provisioned and will not take up all the space right away.

Figure out why the pool is so small. Some ideas that come to mind: small OSDs, or maybe the OSDs are very full and that is the only space left in the cluster? Maybe there is a quota configured for the pool.

The configured size of the disk images have nothing to do with how much space the pool has.
thanks,the reason maybe is your ideas
my external ceph have 3 hosts,have three 10G OSD per host,total 9 OSD ,90G space
i will reset ceph config for verify problem

So 30 GiB of storage per node. With the default size=3 you have 3 replicas. Therefore, the overall usable space is ~30 GiB. 90 GiB raw space / 3 replicas = 30 GiB usable. Everything as expected.
