ince the VM was created? Am I missing something here or is there an automated way of syncing ephemeral disks from time to time with a ceph back end? Thanks Daniel -Original Message- From: Van Leeuwen, Robert [mailto:rovanleeu...@ebay.com] Sent: 16 March 2016 10:15 To: Daniel Nias

Hi, Let me start. Ceph is amazing, no it really is! But a hypervisor reading and writing all its data off the network off the network will add some latency to read and writes. So the hypervisor could do with a local cache, possible SSD or even NVMe. Spent a while looking into this but it seems
