Issue

  • /etc/hosts did not get populated on 3 new compute nodes - Unable to Live Migrate

  • We ran a stack update in February to add these 3 nodes. After a server crash yesterday, we attempted to migrate Vms out of the hypervisor, but all failed. We noticed /etc/hosts did not have any server entries except localhost entries, so we copied from another node, and was able to migrate the Vms Out.

  • Here is an example of /etc/hosts:
