There is also no such thing as "free pool space", you have to look at the free cluster space. But again, if you cluster has X TB of free space and you have multiple pools, your usage will depend on the amount of written data and the replication level. If you want to know the usage of the rbd pool I suggest using "rados df". The RBD tool could however be modified to show the image size if you give another flag. $ rbd --extended ls Wido On 06/18/2012 02:08 PM, Stefan Priebe - Profihost AG wrote: > Stefan > -- > To unsubscribe from this list: send the line "unsubscribe ceph-devel" in > the body of a message to majordomo@vger.kernel.org > More majordomo info at http://vger.kernel.org/majordomo-info.html
