Hi:

I tried get info from a RBD image but:

-------------------------------------------------------------------------
root@fond-beagle:/# rbd list --pool cinder-ceph | grep volume-dfcca6c8-cb96-4b79-bc85-b200a061dcda
volume-dfcca6c8-cb96-4b79-bc85-b200a061dcda

root@fond-beagle:/# rbd info --pool cinder-ceph volume-dfcca6c8-cb96-4b79-bc85-b200a061dcda
rbd: error opening image volume-dfcca6c8-cb96-4b79-bc85-b200a061dcda: (2) No such file or directory

THis is that the metadata show the image but the content was removed?

Sometimes it's easier to run with --debug-rados=20

Then you can see what it tries to fetch from RADOS and where it fails.
That might tell you more.
