Getting started with Trilio on Canonical OpenStack

Trilio and Canonical have started a partnership to ensure a native deployment of Trilio using JuJu Charms.

Those JuJu Charms are publicly available as Open Source Charms.

Prerequisite

A Canonical OpenStack base setup deployed for a required release. Refer Compatibility Matrix

Steps to install the Trilio charms

1. Export the OpenStack base bundle

juju export-bundle --filename openstack_base_file.yaml

2. Create a Trilio overlay bundle as per the OpenStack setup release using the charms given above.

NFS options for Cohesity NFS : nolock,soft,timeo=600,intr,lookupcache=none,nfsvers=3,retrans=10

Trilio File Search functionality requires that the Trilio Workload manager (trilio-wlm) be deployed as a virtual machine. File Search will not function if the Trilio Workload manager (trilio-wlm) is running as a lxd container(s).

If trilio-wlm service is assigned to any nova-compute node then wlm mysql router service fails to start. Hence, please ensure to assign trilio-wlm service to some other node.

Sample Trilio overlay bundles (T4O release wise) can be found at LINK

Alternatively, triliovault-cfg-scripts repository can be cloned to get the sample overlay bundles.

Value of trilio_branch can be taken from release specific Resources

git clone https://github.com/trilioData/triliovault-cfg-scripts.git
cd triliovault-cfg-scripts
git checkout {{ trilio_branch }}
cd juju-charms/sample_overlay_bundles

Following table provides the details of various values to be updated in overlay bundle.

3. T4O Deployment

3.1] Do a dry run to check if the Trilio bundle is working

juju deploy --dry-run ./openstack_base_file.yaml --overlay <Trilio bundle path>

3.2] Trigger deployment

juju deploy ./openstack_base_file.yaml --overlay <Trilio bundle path>

3.3] Wait until all the Trilio units are deployed successfully. Check the status via juju status command.

4. Post Deployment Steps

4.1] Once the deployment is complete, perform the below operations:

a. Create cloud admin trust & add licence

juju run --wait trilio-wlm/leader create-cloud-admin-trust password=<openstack admin password>
juju attach-resource trilio-wlm license=<Path to trilio license file>
juju run --wait trilio-wlm/leader create-license

Note: Reach out to the Trilio support team for the license file.

5. Verify the T4O Deployment

5.1] After T4O deployment steps are over, it can take sometime for all units to get deployed successfully. Deployment is considered successful when all the units show Unit is Ready in the message column.

To verify the same, following command (& sample output) can be used to fetch the Trilio units/applications.

6. Troubleshooting T4O Deployment

6.1] To debug any specific unit : juju debug-log --include <UNIT_NAME_IN_ERROR>

Eg. If trilio-wlm/6 unit is in 'error' state, it's logs can be fetched using following command. Specific correct unit number from respective deployment using juju status command.

juju debug log --include trilio-wlm/6

For multipath enabled environments, perform the following actions

  1. log into each nova compute node

  2. add uxsock_timeout with value as 60000 (i.e. 60 sec) in /etc/multipath.conf

  3. restart tvault-contego service
