Changing the nova user ID on the NetBackup for OpenStack Nodes
NetBackup for OpenStack VM uses the nova user ID and group ID 162:162 by default. Ansible OpenStack is not always nova user ID 162 on nova-compute containers. The nova user ID on the NetBackup for OpenStack VM nodes must be same as the nova-compute containers. If nova ID is not 162:162, perform the following steps on all NetBackup for OpenStack VM nodes.
Before you perform the following steps, verify that the user ID and group ID is not used by any other services on NetBackup for OpenStack VM. For example, If nova ID on compute node is 997, verify that user ID is not used by any other services on NetBackup for OpenStack VM. If 997 user ID is assigned to rabbitmq and 997 group ID is assigned to SSH service on NetBackup for OpenStack VM, you must free this ID.
#cat /etc/passwd | grep 997 #pid 997 #ps -ef | grep 997 #usermod -u 900 rabbitmq #cat /etc/group | grep 997 #groupmod -g 901 ssh_keys #reboot
Go to the directory
/home/stack.Assign the executable permissions to
nova_userid.shfile.#chmod +x nova_userid.sh
Edit script to use the correct nova ID.
Execute the script.
#./nova_userid.sh
Verify that nova user and group ID has changed to the desired value.
#id nova
