Post Installation Health-Check

After the installation and configuration of Trilio for Openstack did succeed the following steps can be done to verify that the Trilio installation is healthy.

Verify the Trilio Appliance services are up

Trilio is using 3 main services on the Trilio Appliance:

wlm-api
wlm-scheduler
wlm-workloads

Those can be verified to be up and running using the systemctl status command.

systemctl status wlm-api

Check the Trilio pacemaker and nginx cluster

The second component to check the Trilio Appliance's health is the nginx and pacemaker cluster.

Verify API connectivity of the Trilio Appliance

Checking the availability of the Trilio API on the chosen endpoints is recommended.

The following example curl command lists the available workload-types and verifies that the connection is available and working:

curl http://10.10.2.34:8780/v1/8e16700ae3614da4ba80a4e57d60cdb9/workload_types/detail -X GET -H "X-Auth-Project-Id: admin" -H "User-Agent: python-workloadmgrclient" -H "Accept: application/json" -H "X-Auth-Token: gAAAAABe40NVFEtJeePpk1F9QGGh1LiGnHJVLlgZx9t0HRrK9rC5vqKZJRkpAcW1oPH6Q9K9peuHiQrBHEs1-g75Na4xOEESR0LmQJUZP6n37fLfDL_D-hlnjHJZ68iNisIP1fkm9FGSyoyt6IqjO9E7_YVRCTCqNLJ67ZkqHuJh1CXwShvjvjw

Please check the API guide for more commands and how to generate the X-Auth-Token.

Verify the tvault-contego services are up and running

The tvault-contego service is the Data Mover that got installed on all compute nodes nodes. It is recommended to check its status after the installation.

Verify the NFS Volume is correctly mounted

Trilio mounts the NFS Backup Target to the Trilio Appliance and Compute nodes.

To verify those are correctly mounted it is recommended to do the following checks.

First df -h looking for /var/triliovault-mounts/<hash-value>

df -h

Secondly do a read / write / delete test as the user nova:nova (uid = 36 / gid = 36) from the Trilio Appliance and the RHV-Host.
