Doc Type: Bug Fix
Doc Text:
Previously, the Compute service only queried local disk statistics on Compute nodes, which are irrelevant when ephemeral disks are stored in RBD. This made it possible for the scheduler to prevent an instance from being scheduled when the total disk usage of instances already running on the node exceeded the total disk capacity as reported by the hypervisor driver. With this update, the Compute service now correctly queries Ceph for actual disk usage statistics.

Description Pádraig Brady 2014-06-20 22:11:07 UTC 
The storage stats of the local compute node is used, rather than that of the RBD ephemeral

Comment 4 Pádraig Brady 2014-11-12 22:36:35 UTC 
Look for the "disk_gb" column from `nova host-describe $hostname`
and ensure it's appropriate for the rbd volume rather than the local disk.
