Hi everyone, When I add a new compute node to the openstack which I deployed some months ago, I meet a problem about the package version incompatible. Detail thing is below: 1. I prepare a clean centos 7 system and add the ip address to the packstack answer file. 2. Run packstack 3. Everything looks fine and I get the successful hint at last. 4. But I find the nova-compute service can't start on new compute node with below log: nova compute service fail to start due to "Connection to the hypervisor is broken on host" 5. I checked the libvirt on compute node, find it has upgrade to the latest version but the old openstack use the old version. And a lot of packages on compute node have the newer version than the old openstack. So I want to know how do you add a new compute node to the old openstack avoid this package version incompatible issue? BTW, I use the default yum repo, so should I maintain a internal static repo for expand the openstack? -BR Andy _______________________________________________ Rdo-list mailing list Rdo-list(a)redhat.com https://www.redhat.com/mailman/listinfo/rdo-list To unsubscribe: rdo-list-unsubscribe(a)redhat.com

Thanks for your reply, Mohammed, the second method seems a better way I can have a try, only one problem I worry about, are you sure the upgrade on all the old node will not break the current environment?
