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.
