[Rdo-list] issue about add compute node

[Mohammed Arafa]

yes you will need to stabilise the package versions in an openstack
deployment. so you better make your own yum repo. but the horses have
bolted already from the barn. so just keep it in mind for the future

right now, what you can do, is to extract/rebuild the rpms on your compute
host and rebuild them to use in your internal static yum repo. see
http://unix.stackexchange.com/questions/140778/how-to-build-an-rpm-package-from-the-installed-files

never tried rpmrebuild but i'd imagine that it would take a huge amount of
time and resources on the compute host. if this is a lab environment, i
suggest re deploying  your set up again.

alternatively, you can do "yum -y upgrade" on all the old nodes, reboot and
voila, all nodes are now up to the same version

thanks
