Subject [jira] [Commented] (CLOUDSTACK-3542) Ceph RBD provides wrong usage info to CloudStack

Indra Pramana commented on CLOUDSTACK-3542:
-------------------------------------------

Hi Frederik,

Wondering if you manage to resolve the issue? I setup a third KVM host and encountered same
issue even after I upgraded to libvirt 1.1.1.

Thank you.
