Instances goes to paused state in Openstack Havanna

Issue: 

All instances in openstack will be in paused node. You will not be able to create new instances or switch on any of the paused instances

Reason: 

Most often the reason will be lack of disk space in your compute node. By default the instances are created in the /var/lib/nova/instances folder of the compute node. This location is defined by the parameter "instances_path" in nova.conf of the  compute node. If your "/" partition is running out of disk space, then you cannot perform any instance related operations

Solution: 

  • Change the "instances_path" location to a different location. Ideally you could attach an additional disk and mount it to a directory and update the directory path in the "instance_path" variable.
     
  • Problem arises when you already have a number of instances  in the previous folder. You should move them over to the new location.
  •  Also you should set the group and ownership of the new instances folder to "nova" user, so that the permissions, ownership and group memberships are same as that of the previous folder

  1. I found proper solution of lack of disk space in your compute node problem on this blog. Now I will try this for kvm openstack. Thanks for sharing
