I mean cluster OSDs are physically full. I understand its not a pretty way to operate CEPH allowing to become full, but I just wanted to know the boundary condition if it becomes full. Will cinder create volume operation creates new volume at all or error is thrown at Cinder API level itself stating that no space available? When IO stalls, will I be able to read the data from CEPH cluster I.e can I still read data from existing volumes created from CEPH cluster? Thanks for the quick reply.
