Doc Text:
When using Red Hat Ceph as a back end for ephemeral storage, the Compute service does not calculate the amount of available storage correctly. Specifically, Compute simply adds up the amount of available storage without factoring in replication. This results in grossly overstated available storage, which in turn could cause unexpected storage oversubscription. To determine the correct ephemeral storage capacity, query the Ceph service directly instead.

Comment 1 Don Domingo 2016-05-16 00:59:54 UTC 
Warnings RE: discrepancy of reported storage for Nova VS Ceph added to CLI Ref and Config Ref of both OSP7 and OSP8.
Comment 2 Don Domingo 2016-08-19 00:47:21 UTC 
Closing this for OSP9 so we can have the warning added to the Release Notes. Cloning for OSP10 for the same reasons, and also so we can track it for OSP10.
