Currently, the reporting of bytes available works well for recommended Ceph deployments that run one OSD per disk [1]. However, for users who are running multiple OSDs on a single disk, the current reporting will reflect bytes available * number of replicas. We can enhance the bytes available reporting method to accomodate unrecommended Ceph deployments by using the MAX_AVAIL stat obtainable via the 'ceph df' command. The MAX_AVAIL stat takes the number of configured replicas into consideration and will reflect the correct number of bytes available even when Ceph is deployed in a way the documentation recommends against. For most users, this change should make no difference. It will only be a help for users who are running unrecommended Ceph deployments.

In the unfortunate event that bugs are discovered, they should be reported to the appropriate bug tracker. If you obtained the software from a 3rd party operating system vendor, it is often wise to use their own bug tracker for reporting problems. In all other cases use the master OpenStack bug tracker, available at:
