Hey folks,
Hi Laurent,
I am trying to see if there are any ways to instruct Openstack to prevent the usage of local storage/ephemeral disks.
There are cases where :
I don't want the added complexity of Ceph. I don't want the added hassle of using local volumes/nfs/shared storage on the computes directly.
In an ideal world, creating a VM would mean that you always have a boot-from-volume with the volume being in your chosen backend.
I've seen this spec : https://blueprints.launchpad.net/nova/+spec/flavor-root-disk-none
But it doesn't seem to have survived the Ocata cycle.
Any thoughts?
You can set the root and ephemeral disk sizes to 0 which means the flavor is not usable without a volume. This way you are forced to use Cinder and what it offers. -yoctozepto
