Subject CEPH Storage Bug
Date Thu, 06 Dec 2012 22:32:17 GMT
I am deploying a 2TB ceph cluster with nothing allocated to it. There appears to be a bug in
the disable threshold that prevents pools from being created. The storage is completely clean,
there is nothing allocated to it. However, cloudstack is showing a 53% usage percentage. unfortunately
the disable threshold is causing issues related to turning up an instance. I am not able to
manually override this.

Bug.
