1. Check replication and degraded object counts: ceph status 2. View per -pool health details: ceph health detail You need to manually trigger a rebalance of the Ceph cluster after OSD changes. How would you safely rebalance the cluster?
systemctl status ovn-northd systemctl status ovn -sbdb systemctl status ovn -nbdb 3. Confirm no failures and services are active. You must configure Open vSwitch (OVS) to connect to the OVN Southbound database. How would you configure the OVS settings?
You need to verify the OVN controller is running on a compute node. What steps would you take?
You need to create a subnet on the shared network for tenant usage. How would you configure the subnet?
ovn-nbctl show You must configure a floating IP address for an instance attached to the shared network. What steps would you perform?
1. Edit the systemd service file for an OpenStack service (e.g., nova -api): vi /etc/systemd/system/openstack -nova -api.service 2. Add the following under the [Service] section: Restart=always RestartSec=5 3. Reload the systemd daemon and apply changes: systemctl daemon -reload 4. Restart and enable the service: systemctl restart openstack -nova -api systemctl enable openstack -nova -api 5. Verify the service restarts on failure by simulating a crash: kill $(pgrep -f nova -api) systemctl status openstack -nova -api An OpenStack deployment is failing due to a misconfiguration in the nova.conf file. How would you identify and fix the configuration issue without disrupting the environment?
