[PackStack][Cinder]Save Volumes in The Compute nodes
Hi,
I have 8 servers with just local HDD disk. I want to use one server as the
controller and network node and the other (7 servers) as the compute node.

I was wondering if it's possible to install PackStack that every compute
node to store its volumes in it's HDD local disk? (I guess the Cinder
should be installed on every Compute node alongside other settings)

Thanks

Yes. You need to enable Cinder’s InstanceLocalityFilter, see
https://docs.openstack.org/cinder/latest/configuration/block-storage/scheduler-filters.html.

Here a tip: https://ask.openstack.org/en/question/92001/cinder-lvm-volume-local-to-instance/

Thanks! and Does it need to cinder module to be installed on compute nodes?

You will need to run the cinder-volume service in the compute nodes. You will have to set it up manually, though, because Packstack only installs it on the controller.
