Hi,

Any FYI more than anything. We have experienced VERY high latency when 
performing IO heavy operations on our RBD volumes. We initially thought 
it was due to network congestion on our uplinks, but it turns out it is 
a bug.

See http://tracker.ceph.com/issues/3737 

It would be great if Proxmox could include this when it is included in 
the stable branch of Ceph.



Regards,




Andrew
