2016-04-28 00:29:34 -0600 answered a question Devstack failed Error on Exit

Good to use stack user to install devstack. We can create stack user and provide sudoers permission with create-stack-user.sh file. Here we are seeing permission issue, so looks like for /opt/stack directory user and group permissions need to be modified.

2016-01-03 15:41:39 -0600 answered a question how to restart service

If you are running devstack environment, you can do restart as below

  1. screen -r
  2. Move to "q-svc" screen. You can move with Ctrl + a + n (for next), Ctrl+a+p (for previous screen) or you can move to specific screen using number ex: Ctrl+a+7
  3. Press Ctrl + c to kill the screen
  4. Press up arrow and Press "Enter" key

Noticed similar failure in my environment. Enabled additional repositories and it worked fine.

  • yum install https://repos.fedorapeople.org/repos/openstack/openstack-juno/rdo-release-juno-1.noarch.rpm (https://repos.fedorapeople.org/repos/...)
  • subscription-manager repos --enable=rhel-7-server-extras-rpms
  • subscription-manager repos --enable=rhel-7-server-optional-rpms
  • subscription-manager repos --enable=rhel-ha-for-rhel-7-server-rpms
  • yum install yum-utils
  • yum install -y openstack-packstack
  • yum update

2015-02-16 08:41:27 -0600 answered a question How to update nova hypervisor to increase space

For the vm i have tried having 160GB hard disk space. Out of that it allocated 50GB for "/" and 102GB for "/home". In this case openstack nova hypervisor created with 49G.

Now created a new vm with 250GB harddisk and allocated partitions manually during OS installation as like "/ - 15G" and "/var -196GB", "/home - 15GB" and now openstack nova-hypervisor got created with 195GB.
