1] [On Undercloud node] Clone latest Trilio repository and upload Trilio puppet module

All commands need to be run as user 'stack' on undercloud node

1.1] Clone Trilio cfg scripts repository

cd /home/stack
mv triliovault-cfg-scripts triliovault-cfg-scripts-old
git clone -b TVO/4.2.8 https://github.com/trilioData/triliovault-cfg-scripts.git
cd triliovault-cfg-scripts/redhat-director-scripts/<RHOSP_RELEASE_DIRECTORY>/

Separate directories are created as per Redhat OpenStack release under 'triliovault-cfg-scripts/redhat-director-scripts/' directory. Use all scripts/templates from respective directory. For ex, if your RHOSP release is 13, then use scripts/templates from 'triliovault-cfg-scripts/redhat-director-scripts/rhosp13' directory only.

Available RHOSP_RELEASE___DIRECTORY values are:

rhosp13 rhosp16.1 rhosp16.2 rhosp17.0

1.2] If backup target type is 'Ceph based S3' with SSL:

If your backup target is ceph S3 with SSL and SSL certificates are self signed or authorized by private CA, then user needs to provide CA chain certificate to validate the SSL requests. For that, user needs to rename his ca chain cert file to 's3-cert.pem' and copy it into the puppet directory of the right release.

cp s3-cert.pem /home/stack/triliovault-cfg-scripts/redhat-director-scripts/<RHOSP_RELEASE_DIRECTORY>/puppet/trilio/files/

2] Upload Trilio puppet module

cd /home/stack/triliovault-cfg-scripts/redhat-director-scripts/<RHOSP_RELEASE_DIRECTORY>/scripts/
./upload_puppet_module.sh

## Output of above command looks like following for RHOSP13, RHOSP16.1 and RHOSP16.2
Creating tarball...
Tarball created.
Creating heat environment file: /home/stack/.tripleo/environments/puppet-modules-url.yaml
Uploading file to swift: /tmp/puppet-modules-8Qjya2X/puppet-modules.tar.gz

| puppet-modules.tar.gz | overcloud-artifacts | 368951f6a4d39cfe53b5781797b133ad |
+-----------------------+---------------------+----------------------------------+

## Output of above command looks like following for RHOSP17.0
Creating tarball...
Tarball created.
renamed '/tmp/puppet-modules-P3duCg9/puppet-modules.tar.gz' -> '/var/lib/tripleo/artifacts/overcloud-artifacts/puppet-modules.tar.gz'

## Above command creates following file.
ls -ll /home/stack/.tripleo/environments/puppet-modules-url.yaml

3] Update overcloud roles data file to include Trilio services

Trilio has two services as explained below. You need to add these two services to your roles_data.yaml. If you do not have customized roles_data file, you can find your default roles_data.yaml file at /usr/share/openstack-tripleo-heat-templates/roles_data.yaml on undercloud.

You need to find that role_data file and edit it to add the following Trilio services.

i) Trilio Datamover Api Service:

Service Entry in roles_data yaml: OS::TripleO::Services::TrilioDatamoverApi

This service needs to be co-located with database and keystone services. That said, you need to add this service on the same role as of keystone and database service.

Typically this service should be deployed on controller nodes where keystone and database runs. If you are using RHOSP's pre-defined roles, you need to addOS::TripleO::Services::TrilioDatamoverApiservice to Controller role.

ii) Trilio Datamover Service: Service Entry in roles_data yaml: OS::TripleO::Services::TrilioDatamover This service should be deployed on role where nova-compute service is running.

If you are using RHOSP's pre-defined roles, you need to add our OS::TripleO::Services::TrilioDatamover service to Compute role.

If you have defined your custom roles, then you need to identify the role name where in 'nova-compute' service is running and then you need to add 'OS::TripleO::Services::TrilioDatamover' service to that role.

iii) Trilio Horizon Service:

This service needs to share the same role as the OpenStack Horizon server. In the case of the pre-defined roles will the Horizon service run on the role Controller. Add the following to the identified role OS::TripleO::Services::TrilioHorizon

4] Prepare latest Trilio container images

All commands need to be run as user 'stack'

Trilio containers are pushed to 'RedHat Container Registry'. Registry URL is 'registry.connect.redhat.com'. The Trilio container URLs are as follows:

Refer to the word <HOTFIX-TAG-VERSION> as 4.2.8 in the below sections

4.1] available container images

Trilio horizon plugin:            registry.connect.redhat.com/trilio/trilio-horizon-plugin:<HOTFIX-TAG-VERSION>-rhosp17.0

There are three registry methods available in RedHat Openstack Platform.

  1. Remote Registry

  2. Local Registry

  3. Satellite Server

4.2] Remote Registry

Please refer to the following overview to see which containers are available.

Follow this section when 'Remote Registry' is used.

For this method it is not necessary to pull the containers in advance. It is only necessary to populate the trilio_env.yaml file with the Trilio container URLs from Redhat registry.

Populate the trilio_env.yaml with container URLs for:

  • Trilio Datamover container

  • Trilio Datamover api container

  • Trilio Horizon Plugin

trilio_env.yaml will be available in __triliovault-cfg-scripts/redhat-director-scripts/<RHOSP_RELEASE_DIRECTORY>/environments

Example

# For RHOSP13
$ grep 'Image' trilio_env.yaml
   DockerTrilioDatamoverImage: registry.connect.redhat.com/trilio/trilio-datamover:<HOTFIX-TAG-VERSION>-rhosp13
   DockerTrilioDmApiImage: registry.connect.redhat.com/trilio/trilio-datamover-api:<HOTFIX-TAG-VERSION>-rhosp13
   DockerHorizonImage: registry.connect.redhat.com/trilio/trilio-horizon-plugin:<HOTFIX-TAG-VERSION>-rhosp13

# For RHOSP16.1
$ grep 'Image' trilio_env.yaml
   DockerTrilioDatamoverImage: registry.connect.redhat.com/trilio/trilio-datamover:<HOTFIX-TAG-VERSION>-rhosp16.1
   DockerTrilioDmApiImage: registry.connect.redhat.com/trilio/trilio-datamover-api:<HOTFIX-TAG-VERSION>-rhosp16.1
   ContainerHorizonImage: registry.connect.redhat.com/trilio/trilio-horizon-plugin:<HOTFIX-TAG-VERSION>-rhosp16.1
   
# For RHOSP16.2

   DockerTrilioDatamoverImage: registry.connect.redhat.com/trilio/trilio-datamover:<HOTFIX-TAG-VERSION>-rhosp16.2
   DockerTrilioDmApiImage: registry.connect.redhat.com/trilio/trilio-datamover-api:<HOTFIX-TAG-VERSION>-rhosp16.2
   ContainerHorizonImage: registry.connect.redhat.com/trilio/trilio-horizon-plugin:<HOTFIX-TAG-VERSION>-rhosp16.2

# For RHOSP17.0
$ grep 'Image' trilio_env.yaml
   DockerTrilioDatamoverImage: registry.connect.redhat.com/trilio/trilio-datamover:<HOTFIX-TAG-VERSION>-rhosp17.0
   DockerTrilioDmApiImage: registry.connect.redhat.com/trilio/trilio-datamover-api:<HOTFIX-TAG-VERSION>-rhosp17.0
   ContainerHorizonImage: registry.connect.redhat.com/trilio/trilio-horizon-plugin:<HOTFIX-TAG-VERSION>-rhosp17.0

4.2] Local Registry

Please refer to the this overview to see which containers are available.

Follow this section when 'local registry' is used on the undercloud.

In this case it is necessary to push the Trilio containers to the undercloud registry. Trilio provides shell scripts which will pull the containers from 'registry.connect.redhat.com' and push them to the undercloud and updates the trilio_env.yaml.

RHOSP13 example

cd /home/stack/triliovault-cfg-scripts/redhat-director-scripts/<RHOSP_RELEASE_DIRECTORY>/scripts/

./prepare_trilio_images.sh <undercloud_ip> <container_tag>

# Example:
./prepare_trilio_images.sh 192.168.13.34 <HOTFIX-TAG-VERSION>-rhosp13

## Verify changes
# For RHOSP13
$ grep '4.2.6-rhosp13' ../environments/trilio_env.yaml

   DockerTrilioDmApiImage: 172.25.2.2:8787/trilio/trilio-datamover-api:<HOTFIX-TAG-VERSION>-rhosp13
   DockerHorizonImage: 172.25.2.2:8787/trilio/trilio-horizon-plugin:<HOTFIX-TAG-VERSION>-rhosp13

RHOSP 16.1, RHOSP16.2 and RHOSP17.0 example

cd /home/stack/triliovault-cfg-scripts/redhat-director-scripts/<RHOSP_RELEASE_DIRECTORY>/scripts/

sudo ./prepare_trilio_images.sh <UNDERCLOUD_REGISTRY_HOSTNAME> <CONTAINER_TAG> 

## Run following command to find 'UNDERCLOUD_REGISTRY_HOSTNAME'. 
-- In the below example 'trilio-undercloud.ctlplane.localdomain' is <UNDERCLOUD_REGISTRY_HOSTNAME>
$ openstack tripleo container image list | grep keystone
| docker://trilio-undercloud.ctlplane.localdomain:8787/rhosp-rhel8/openstack-keystone:16.0-82                       |
| docker://trilio-undercloud.ctlplane.localdomain:8787/rhosp-rhel8/openstack-barbican-keystone-listener:16.0-84   

## 'CONTAINER_TAG' format for RHOSP16.1: <<HOTFIX-TAG-VERSION>>-rhosp16.1
## 'CONTAINER_TAG' format for RHOSP16.2: <<HOTFIX-TAG-VERSION>>-rhosp16.2
## 'CONTAINER_TAG' format for RHOSP17.0: <<HOTFIX-TAG-VERSION>>-rhosp17.0

## Example
sudo ./prepare_trilio_images.sh trilio-undercloud.ctlplane.localdomain <HOTFIX-TAG-VERSION>-rhosp16.1

The changes can be verified using the following commands.

4.3] Red Hat Satellite Server

Please refer to the following overview to see which containers are available.

Follow this section when a Satellite Server is used for the container registry.

Pull the Trilio containers on the Red Hat Satellite using the given Red Hat registry URLs.

Populate the trilio_env.yaml with container urls.

RHOSP 13 example

$ grep '<HOTFIX-TAG-VERSION>-rhosp13' ../environments/trilio_env.yaml
   DockerTrilioDatamoverImage: <SATELLITE_REGISTRY_URL>/trilio/trilio-datamover:<HOTFIX-TAG-VERSION>-rhosp13

   ContainerHorizonImage: <SATELLITE_REGISTRY_URL>/trilio/trilio-horizon-plugin:<HOTFIX-TAG-VERSION>-rhosp17.0

5. Verify Trilio environment details

It is recommended to re-populate the backup target details in the freshly downloaded trilio_env.yaml file. This will ensure that parameters that have been added since the last update/installation of Trilio are available and will be filled out too.

Locations of the trilio_env.yaml:

RHOSP13: /home/stack/triliovault-cfg-scripts/redhat-director-scripts/rhosp13/environments/trilio_env.yaml
RHOSP16.1: /home/stack/triliovault-cfg-scripts/redhat-director-scripts/rhosp16.1/environments/trilio_env.yaml
RHOSP16.2: /home/stack/triliovault-cfg-scripts/redhat-director-scripts/rhosp16.2/environments/trilio_env.yaml
RHOSP17.0: /home/stack/triliovault-cfg-scripts/redhat-director-scripts/rhosp17.0/environments/trilio_env.yaml

For more details about the trilio_env.yaml please check here.

6] Configure multi-IP NFS

This section is only required when the multi-IP feature for NFS is required.

This feature allows to set the IP to access the NFS Volume per datamover instead of globally.

On Undercloud node, change directory

cd triliovault-cfg-scripts/common/

Edit file 'triliovault_nfs_map_input.yml' in the current directory and provide compute host and NFS share/ip map.

Get the compute hostnames from the following command. Check ‘Name' column. Use exact hostnames in 'triliovault_nfs_map_input.yml' file.

Run this command on undercloud by sourcing 'stackrc'.

(undercloud) [stack@ucqa161 ~]$ openstack server list

+--------------------------------------+-------------------------------+--------+----------------------+----------------+---------+

Edit input map file and fill all the details. Refer to the this page for details about the structure.

vi triliovault_nfs_map_input.yml

Update pyyaml on the undercloud node only

If pip isn't available please install pip on the undercloud.

## On Python3 env 
sudo pip3 install PyYAML==5.1 3 

## On Python2 env 
sudo pip install PyYAML==5.1

Expand the map file to create a one-to-one mapping of the compute nodes and the nfs shares.

## On Python3 env 
python3 ./generate_nfs_map.py 
 
## On Python2 env 
python ./generate_nfs_map.py

The result will be in file - 'triliovault_nfs_map_output.yml'

Validate output map file

Open file 'triliovault_nfs_map_output.yml

vi triliovault_nfs_map_output.yml

available in the current directory and validate that all compute nodes are covered with all the necessary NFS shares.

Append this output map file to 'triliovault-cfg-scripts/redhat-director-scripts/<RHOSP_RELEASE_DIRECTORY>/environments/trilio_nfs_map.yaml'

grep ':.*:' triliovault_nfs_map_output.yml >> ../redhat-director-scripts/<RHOSP_RELEASE_DIRECTORY>/environments/trilio_nfs_map.yaml

Validate the changes in file 'triliovault-cfg-scripts/redhat-director-scripts/<RHOSP_RELEASE_DIRECTORY>/environments/trilio_nfs_map.yaml'

Include the environment file (trilio_nfs_map.yaml) in overcloud deploy command with '-e' option as shown below.

-e /home/stack/triliovault-cfg-scripts/redhat-director-scripts/<RHOSP_RELEASE_DIRECTORY>/environments/trilio_nfs_map.yaml

Ensure that MultiIPNfsEnabled is set to true in trilio_env.yaml file and that nfs is used as backup target.

7] Update Overcloud Trilio components

Use the following heat environment file and roles data file in overcloud deploy command:

  1. trilio_env.yaml

  2. roles_data.yaml

  3. Use correct Trilio endpoint map file as per available Keystone endpoint configuration

    1. Instead of tls-endpoints-public-dns.yaml file, use environments/trilio_env_tls_endpoints_public_dns.yaml

    2. Instead of tls-endpoints-public-ip.yaml file, useenvironments/trilio_env_tls_endpoints_public_ip.yaml

    3. Instead of tls-everywhere-endpoints-dns.yaml file, useenvironments/trilio_env_tls_everywhere_dns.yaml

To include new environment files use '-e' option and for roles data file use '-r' option. An example overcloud deploy command is shown below:

openstack overcloud deploy --templates \
  -e /home/stack/templates/node-info.yaml \
  -e /home/stack/templates/overcloud_images.yaml \
  -e /home/stack/triliovault-cfg-scripts/redhat-director-scripts/rhosp16.1/environments/trilio_env.yaml \
  -e /usr/share/openstack-tripleo-heat-templates/environments/ssl/enable-tls.yaml \
  -e /usr/share/openstack-tripleo-heat-templates/environments/ssl/inject-trust-anchor.yaml \
  -e /home/stack/triliovault-cfg-scripts/redhat-director-scripts/rhosp16.1/environments/trilio_env_tls_endpoints_public_dns.yaml \
  -e /home/stack/triliovault-cfg-scripts/redhat-director-scripts/rhosp16.1/environments/trilio_nfs_map.yaml \
  --ntp-server 192.168.1.34 \
  --libvirt-type qemu \
  --log-file overcloud_deploy.log \
  -r /home/stack/templates/roles_data.yaml

8] Verify deployment

If the containers are in restarting state or not listed by the following command then your deployment is not done correctly. Please recheck if you followed the complete documentation.

8.1] On Controller node

Make sure Trilio dmapi and horizon containers are in a running state and no other Trilio container is deployed on controller nodes. When the role for these containers is not "controller" check on respective nodes according to configured roles_data.yaml.

[root@overcloud-controller-0 heat-admin]# podman ps | grep trilio
26fcb9194566  rhosptrainqa.ctlplane.localdomain:8787/trilio/trilio-datamover-api:<HOTFIX-TAG-VERSION>-rhosp16.2        kolla_start           5 days ago  Up 5 days ago         trilio_dmapi
094971d0f5a9  rhosptrainqa.ctlplane.localdomain:8787/trilio/trilio-horizon-plugin:<HOTFIX-TAG-VERSION>-rhosp16.2       kolla_start           5 days ago  Up 5 days ago         horizon

8.2] On Compute node

Make sure Trilio datamover container is in running state and no other Trilio container is deployed on compute nodes.

[root@overcloud-novacompute-0 heat-admin]# podman ps | grep trilio
b1840444cc59  rhosptrainqa.ctlplane.localdomain:8787/trilio/trilio-datamover:<HOTFIX-TAG-VERSION>-rhosp16.2                    kolla_start           5 days ago  Up 5 days ago         trilio_datamover

8.3] On the node with Horizon service

Make sure horizon container is in running state. Please note that 'Horizon' container is replaced with Trilio Horizon container. This container will have latest OpenStack horizon + Trilio's horizon plugin.

[root@overcloud-controller-0 heat-admin]# podman ps | grep horizon
094971d0f5a9  rhosptrainqa.ctlplane.localdomain:8787/trilio/trilio-horizon-plugin:<HOTFIX-TAG-VERSION>-rhosp16.2       kolla_start           5 days ago  Up 5 days ago         horizon

If Trilio Horizon container is in restarted state on RHOSP 16.1.8/RHSOP 16.2.4 then use below workaroud

## Either of the below workarounds should be performed on all the controller nodes where issue occurs for horizon pod.

option-1: Restart the memcached service on controller using systemctl (command: systemctl restart tripleo_memcached.service)

option-2: Restart the memcached pod (command: podman restart memcached)

9] Enable mount-bind for NFS

T4O 4.2 has changed the calculation of the mount point. It is necessary to set up the mount-bind to make T4O 4.1 or older backups available for T4O 4.2

Please follow this documentation to set up the mount bind for RHOSP.
