Do you need to tell the vm's that they are on a ssd rbd pool? Or does ceph and the libvirt drivers do this automatically for you? When testing a nutanix acropolis virtual install, I had to 'cheat' it by adding this <qemu:arg value='device.scsi0-0-0-1.rotation_rate=1'/> To make the installer think there was a ssd drive. I only have 'Thin provisioned drive' mentioned regardless if the vm is on a hdd rbd pool or a ssd rbd pool. _______________________________________________ ceph-users mailing list ceph-users@xxxxxxxxxxxxxx http://lists.ceph.com/listinfo.cgi/ceph-users-ceph.com
