Hi All,
This seems to be a weird issue. Firstly all deployment is
done with "ceph-deploy" and 3 host machines acting as MON and
OSD using the Hammer release on Ubuntu 14.04.3 and running KVM
(libvirt).
When using vanilla CEPH, single rbd pool no log device or
cache tiering, the virtual machine will start without any
problem. I can see CEPH doing data work and the virtual machine
runs the OS installer fine.
However when I enable cache tiering so that I have a separate
RBD and SSD pool, libvirt is unable to start and virtual
machines at all with an error of a feature I think CEPH disabled
(not sure). This is entirely repeatable as I did re-installs of
software and even the operating system.
I'm not sure if it is CEPH in this case but it only seems to
happen when doing cache tiering which leads me to believe it has
some of the blame.
*snipsnap*
Did you grant access to the cache tier pool for the libvirt ceph
user?
Best regards,
Burkhard
