ctlplane-ip-range

Check the number of IP addresses available to overcloud nodes.

Verify that the number of IP addresses defined in dhcp_start and dhcp_end fields in undercloud.conf is not too low.

  • groups: pre-introspection
  • metadata:
  • parameters:
    • ctlplane_iprange_min_size: 25

undercloud-cpu

Verify undercloud fits the CPU core requirements.

Make sure that the undercloud has enough CPU cores. https://access.redhat.com/documentation/en-US/Red_Hat_Enterprise_Linux_OpenStack_Platform/7/html/Director_Installation_and_Usage/sect-Undercloud_Requirements.html

undercloud-disk-space

Verify undercloud fits the disk space requirements.

Make sure that the root partition on the undercloud node is large enough. We first check for an explicit /var mount point since that’s where we store logs and images and if it doesn’t exist, we fall back to /. http://tripleo.org/environments/environments.html#id5

undercloud-tokenflush

Verify token_flush is enabled in keystone users crontab..

Without a token_flush crontab enabled for the keystone user, the keystone database can grow very large. This validation checks that the keystone token_flush crontab has been set up.
