Installing on Ansible Openstack

Please ensure that the Trilio Appliance has been updated to the latest hotfix before continuing the installation.

Change the nova user id on the Trilio Nodes

The 'nova' user ID and Group ID on the Trilio nodes need to be set the same as in the compute node(s). Trilio is by default using the nova user ID (UID) and Group ID (GID) 162:162. Ansible OpenStack is not always 'nova' user id 162 on compute node. Do the following steps on all Trilio nodes in case of nova UID & GID are not in sync with the Compute Node(s)

Download the shell script that will change the user-id
Assign executable permissions
Edit script to use the correct nova id
Execute the script
Verify that 'nova' user and group id has changed to the desired value

curl -O https://raw.githubusercontent.com/trilioData/triliovault-cfg-scripts/master/common/nova_userid.sh
chmod +x nova_userid.sh
vi nova_userid.sh  # change nova user_id and group_id to uid & gid present on compute nodes. 
./nova_userid.sh
id nova

Prepare deployment host

Clone triliovault-cfg-scripts from github repository on Ansible Host.

git clone -b <branch> https://github.com/trilioData/triliovault-cfg-scripts.git

Available values for <branch>: hotfix-4-TVO/4.2

Copy Ansible roles and vars to required places.

cd triliovault-cfg-scripts/
cp -R ansible/roles/* /opt/openstack-ansible/playbooks/roles/
cp ansible/main-install.yml   /opt/openstack-ansible/playbooks/os-tvault-install.yml
cp ansible/environments/group_vars/all/vars.yml /etc/openstack_deploy/user_tvault_vars.yml
cp ansible/tvault_pre_install.yml /opt/openstack-ansible/playbooks/

In case of installing on OSA Victora or OSA Wallaby edit OPENSTACK_DIST in the file /etc/openstack_/user_tvault_vars.yml to victoria or wallaby respectively

Add Trilio playbook to /opt/openstack-ansible/playbooks/setup-openstack.ymlat the end of the file.

- import_playbook: os-tvault-install.yml

Add the following content at the end of the file /etc/openstack_deploy/user_variables.yml

# Datamover haproxy setting
haproxy_extra_services:
  - service:
      haproxy_service_name: datamover_service

Create the following file /opt/openstack-ansible/inventory/env.d/tvault-dmapi.yml

Add the following content to the created file.

cat > /opt/openstack-ansible/inventory/env.d/tvault-dmapi.yml

  tvault-dmapi_containers:
    belongs_to:
      - all_containers
  tvault-dmapi_hosts:
    belongs_to:
      - hosts

Edit the file /etc/openstack_deploy/openstack_user_config.yml according to the example below to set host entries for Trilio components.

#tvault-dmapi
tvault-dmapi_hosts:   # Add controller details in this section as tvault DMAPI is resides on controller nodes.
  infra-1:            # controller host name. 
    ip: 172.26.0.3    # Ip address of controller
  infra-2:            # If we have multiple controllers add controllers details in same manner as shown in Infra-2  
    ip: 172.26.0.4    
    
#tvault-datamover
tvault_compute_hosts: # Add compute details in this section as tvault datamover is resides on compute nodes.
  infra-1:            # compute host name. 
    ip: 172.26.0.7    # Ip address of compute node
  infra-2:            # If we have multiple compute nodes add compute details in same manner as shown in Infra-2
    ip: 172.26.0.8

Edit the common editable parameter section in the file /etc/openstack_deploy/user_tvault_vars.yml

Append the required details like Trilio Appliance IP address, Openstack distribution, snapshot storage backend, SSL related information, etc.

Note:

From 4.2HF4 onwards default prefilled value i.e 4.2.64 will be used for TVAULT_PACKAGE_VERSION .
In case of more than one nova virtual environment If the user wants to install tvault-contego service in a specific nova virtual environment on compute node(s) then needs to uncomment var nova_virtual_env and then set the value of nova_virtual_env
In case of more than one horizon plugin configured on openstack user can specify under which horizon plugins to install Trilio Horizon Plugins by setting horizon_virtual_env parameter. Default value of horizon_virtual_env is ' /openstack/venvs/horizon*'\

Configure Multi-IP NFS

This step is only required when the multi-IP NFS feature is used to connect different datamovers to the same NFS volume through multiple IPs

New parameter added to /etc/openstack_deploy/user_tvault_vars.yml file for Mutli-IP NFS\

## Valid for 'nfs' backup target only.
## If backup target NFS share supports multiple endpoints/ips but in backend it's a single share then 
## set 'multi_ip_nfs_enabled' paremeter to 'True'. Otherwise it's value should be 'False'
multi_ip_nfs_enabled: False

Change the Directory

cd triliovault-cfg-scripts/common/

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

Please take a look at this page to learn about the format of the file.

vi triliovault_nfs_map_input.yml

Update pyyaml on the Openstack Ansible server node only

pip3 install -U pyyaml

Execute generate_nfs_map.py file to create one to one mapping of compute and nfs share.

python ./generate_nfs_map.py

Result will be in file - 'triliovault_nfs_map_output.yml' of the current directory

Validate output map file Open file 'triliovault_nfs_map_output.yml

vi triliovault_nfs_map_output.yml

available in current directory and validate that all compute nodes are mapped with all necessary nfs shares.

Append the content of triliovault_nfs_map_output.yml file to /etc/openstack_deploy/user_tvault_vars.yml

cat triliovault_nfs_map_output.yml >> /etc/openstack_deploy/user_tvault_vars.yml

Deploy Trilio components

Run the following commands to deploy only Trilio components in case of an already deployed Ansible Openstack.

cd /opt/openstack-ansible/playbooks

## Run tvault_pre_install.yml to install lxc packages
ansible-playbook tvault_pre_install.yml

# To create Dmapi container
openstack-ansible lxc-containers-create.yml 

#To Deploy Trilio Components
openstack-ansible os-tvault-install.yml

#To configure Haproxy for Dmapi
openstack-ansible haproxy-install.yml

If Ansible Openstack is not already deployed then run the native Openstack deployment commands to deploy Openstack and Trilio Components together. An example for the native deployment command is given below:

openstack-ansible setup-infrastructure.yml --syntax-check
openstack-ansible setup-hosts.yml
openstack-ansible setup-infrastructure.yml
openstack-ansible setup-openstack.yml

Verify the Trilio deployment

Verify triliovault datamover api service deployed and started well. Run the below commands on controller node(s).

lxc-ls                                           # Check the dmapi container is present on controller node.
lxc-info -s controller_dmapi_container-a11984bf  # Confirm running status of the container

Verify triliovault datamover service deployed and started well on compute node(s). Run the following command oncompute node(s).

systemctl status tvault-contego.service
systemctl status tvault-object-store  # If Storage backend is S3
df -h                                 # Verify the mount point is mounted on compute node(s)

Verify that triliovault horizon plugin, contegoclient, and workloadmgrclient are installed on the Horizon container.

Run the following command on Horizon container.

lxc-attach -n controller_horizon_container-1d9c055c                                   # To login on horizon container
apt list | egrep 'tvault-horizon-plugin|workloadmgrclient|contegoclient'              # For ubuntu based container
dnf list installed |egrep 'tvault-horizon-plugin|workloadmgrclient|contegoclient'     # For CentOS based container

Verify that haproxy setting on controller node using below commands.

 haproxy -c -V -f /etc/haproxy/haproxy.cfg # Verify the keyword datamover_service-back is present in output.

Update to the latest hotfix

After the deployment has been verified it is recommended to update to the latest hotfix to ensure the best possible experience.

To update the environment follow this procedure.
