Hi Team,, Upon further debugging, I found that pre-introspection internally calls the ansible playbook located at path /usr/share/ansible/validation-playbooks File "dhcp-introspection.yaml" has hosts mentioned as undercloud. - hosts: *undercloud* become: true vars: ... ... But the artifacts created for dhcp-introspection at location /home/stack/validations/artifacts/<some_random_number>_dhcp-introspection.yaml_2021-10-01T11 has file *hosts *present which has *localhost* written into it as a result of which when command gets executed it gives the error *"Could not match supplied host pattern, ignoring: undercloud:"* Can someone suggest how is this artifacts written in tripleo and the way we can change hosts file entry to undercloud so that it can work Similar is the case with other tasks like undercloud-tokenflush, ctlplane-ip-range etc Regards Anirudh Gupta On Wed, Sep 29, 2021 at 4:47 PM Anirudh Gupta <anyrude10@gmail.com> wrote:
Hi Team,
I tried installing Undercloud using the below link:
https://docs.openstack.org/project-deploy-guide/tripleo-docs/latest/deployme...
I am getting the following error:
(undercloud) [stack@undercloud ~]$ openstack tripleo validator run --group pre-introspection Selected log directory '/home/stack/validations' does not exist. Attempting to create it.

As per the validation link,
https://docs.openstack.org/tripleo-validations/wallaby/validations-pre-intro...
check-network-gateway
If gateway in undercloud.conf is different from local_ip, verify that the gateway exists and is reachable
Observation - In my case IP specified in local_ip and gateway, both are pingable, but still this error is being observed
ctlplane-ip-range¶ <https://docs.openstack.org/tripleo-validations/wallaby/validations-pre-introspection-details.html#ctlplane-ip-range>
Check the number of IP addresses available for the overcloud nodes.
Verify that the number of IP addresses defined in dhcp_start and dhcp_end fields in undercloud.conf is not too low.
-
ctlplane_iprange_min_size: 20
Observation - In my case I have defined more than 20 IPs
Similarly for disk related issue, I have dedicated 100 GB space in /var and /
Filesystem Size Used Avail Use% Mounted on devtmpfs 12G 0 12G 0% /dev tmpfs 12G 84K 12G 1% /dev/shm tmpfs 12G 8.7M 12G 1% /run tmpfs 12G 0 12G 0% /sys/fs/cgroup /dev/mapper/cl-root 100G 2.5G 98G 3% / /dev/mapper/cl-home 47G 365M 47G 1% /home /dev/mapper/cl-var 103G 1.1G 102G 2% /var /dev/vda1 947M 200M 747M 22% /boot tmpfs 2.4G 0 2.4G 0% /run/user/0 tmpfs 2.4G 0 2.4G 0% /run/user/1000
Despite setting al the parameters, still I am not able to pass pre-introspection checks. *"NO Host Matched" *is found in the table.
