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
