pre-deployment¶
512e¶
Advanced Format 512e Support.
Detect whether the undercloud disks use Advanced Format. If they do, the overcloud images may fail to upload to Glance.
- hosts: undercloud
- groups: prep, pre-deployment
- parameters:
- roles: advanced-format-512e-support
Role documentation
ceilometerdb-size¶
Events Database Size Check.
The undercloud’s events database can grow to a substantial size if event_time_to_live is set to a negative value (infinite limit). This validation checks event_time_to_live and fails if the variable is set to a negative value or if it has no custom setting (their value is -1 by default).
- hosts: undercloud
- groups: pre-deployment
- parameters:
- event_ttl_check: event_time_to_live
- panko_config_file: /var/lib/config-data/puppet-generated/panko/etc/panko/panko.conf
- roles: ceilometerdb-size
Role documentation
ceph-ansible-installed¶
Check if ceph-ansible is installed on the undercloud.
Prints a message if ceph-ansible isn’t installed
- hosts: undercloud
- groups: pre-deployment
- parameters:
- fail_without_ceph_ansible: False
- roles: ceph
Role documentation
collect-flavors-and-verify-profiles¶
Collect and verify role flavors.
This validation checks the flavors assigned to roles exist and have the correct capabilities set.
- hosts: undercloud
- groups: pre-deployment, pre-upgrade
- parameters:
- roles: collect-flavors-and-verify-profiles
Role documentation
default-node-count¶
Verify hypervisor statistics.
This validation checks that the nodes and hypervisor statistics add up.
- hosts: undercloud
- groups: pre-deployment
- parameters:
- roles: default-node-count
Role documentation
dhcp-provisioning¶
DHCP on the Provisioning Network.
An unexpected DHCP server on the provisioning network can cause problems with deploying the Ironic nodes. This validation checks for DHCP responses on the undercloud’s provisioning interface (eth1 by default) and fails if there are any.
- hosts: undercloud
- groups: pre-deployment
- parameters:
- roles: dhcp-validations
Role documentation
dns¶
Verify DNS.
Verify that the DNS resolution works
- hosts: undercloud, overcloud
- groups: pre-deployment
- parameters:
- server_to_lookup: example.com
- roles: dns
Role documentation
ironic-boot-configuration¶
Check Ironic boot configuration.
Check if baremetal boot configuration is correct.
- hosts: undercloud
- groups: pre-deployment, pre-upgrade
- parameters:
- deploy_kernel_name_base: bm-deploy-kernel
- deploy_ramdisk_name_base: bm-deploy-ramdisk
- roles: ironic-boot-configuration
Role documentation
network-environment¶
Validate the Heat environment file for network configuration.
This validates the network environment and nic-config files that specify the overcloud network configuration and are stored in the current plan’s Swift container. The deployers are expected to write these files themselves as described in the Network Isolation guide: http://tripleo.org/advanced_deployment/network_isolation.html
- hosts: undercloud
- groups: pre-deployment
- parameters:
- network_environment_path: environments/network-environment.yaml
- plan_env_path: plan-environment.yaml
- ip_pools_path: environments/ips-from-pool-all.yaml
- roles: network-environment
Role documentation
node-disks¶
Check node disk configuration.
Check node disk numbers and sizes and whether root device hints are set.
- hosts: undercloud
- groups: pre-deployment
- parameters:
- ironic_conf_file: /var/lib/config-data/puppet-generated/ironic/etc/ironic/ironic.conf
- roles: node-disks
Role documentation
service-status¶
Ensure services state.
Detect services status on the target host and fails if we find a failed service.
- hosts: undercloud, overcloud
- groups: prep, pre-deployment, pre-upgrade, post-deployment, post-upgrade
- parameters:
- roles: service-status
Role documentation
switch-vlans¶
Compare switch port VLANs to VLANs in nic config.
LLDP data received during introspection contains the configured VLANs for each switch port attached to the nodes interfaces. Compare the VLAN IDs set on the switch port to those configured in nic config files. Since the mapping of roles to nodes isn’t known prior to deployment, this check can only check VLANs across all switch ports, not on a particular switch port.
- hosts: undercloud
- groups: pre-deployment
- parameters:
- network_environment_path: environments/network-environment.yaml
- ironic_inspector_conf_file: /var/lib/config-data/puppet-generated/ironic_inspector/etc/ironic-inspector/inspector.conf
- roles: switch-vlans
Role documentation
undercloud-debug¶
Undercloud Services Debug Check.
The undercloud’s openstack services should _not_ have debug enabled. This will check if debug is enabled on undercloud services. If debug is enabled, the root filesystem can fill up quickly, and is not a good thing.
- hosts: undercloud
- groups: pre-deployment
- parameters:
- debug_check: True
- roles: undercloud-debug
Role documentation
undercloud-heat-purge-deleted¶
Verify heat-manage purge_deleted is enabled in crontab.
Without a purge_deleted crontab enabled, the heat database can grow very large. This validation checks that the purge_deleted crontab has been set up.
- hosts: undercloud
- groups: pre-upgrade, pre-deployment
- parameters:
- cron_check: heat-manage purge_deleted
- roles: undercloud-heat-purge-deleted
Role documentation
undercloud-process-count¶
Check the number of OpenStack processes on undercloud.
The default settings for OpenStack is to run one process (heat-engine, keystone, etc.) per CPU core. On a machine with a lot of cores this is both unnecessary and can consume a significant amount of RAM, leading to crashes due to OOMKiller.
- hosts: undercloud
- groups: pre-deployment
- parameters:
- max_process_count: 8
- roles: undercloud-process-count
