Installing on RHOSP16.0
The Red Hat Openstack Platform Director is the supported and recommended method to deploy and maintain any RHOSP installation.
Trilio is integrating natively into the RHOSP Director. Manual deployment methods are not supported for RHOSP.
Prepare for deployment
Depending whether the RHOSP environment is already installed or is getting installed for the first time different steps are done to be able to deploy Trilio.
All commands need to be run as user 'stack'
The following commands upload the Trilio puppet module to the overcloud. The actual upload happens upon the next deployment.
Gitub branches to use:
Trilio 4.0 GA == stable/4.0 Trilio 4.0 SP1 == v4.0maintenance
Update overcloud roles data file to include Trilio services
Trilio contains of multiple services. Add these services to your roles_data.yaml.
In case of uncostomized roles_data.yaml can the default file be found on the undercloud at:
/usr/share/openstack-tripleo-heat-templates/roles_data.yaml
Add the following services to the roles_data.yaml
Trilio Datamover Api Service
This service needs to share the same role as the nova-api
service.
In case of the pre-defined roles will the nova-api
service run on the role Controller
.
In case of custom defined roles, it is necessary to use the role the nova-api
service is using.
Add the following line to the identified role:
Trilio Datamover Service
This service needs to share the same role as the nova-compute
service.
In case of the pre-defined roles will the nova-compute
service run on the role Compute
.
In case of custom defined roles, it is necessary to use the role the nova-compute
service is using.
Add the following line to the identified role:
Prepare Trilio container images
All commands need to be run as user 'stack'
Trilio containers are pushed to 'RedHat Container Registry'. Registry URL: 'registry.connect.redhat.com'. Container pull urls are given below.
Trilio Datamover container: registry.connect.redhat.com/trilio/trilio-datamover:<container-tag>
Trilio Datamover Api Container: registry.connect.redhat.com/trilio/trilio-datamover-api:<container-tag>
Trilio horizon plugin: registry.connect.redhat.com/trilio/trilio-horizon-plugin:<container-tag>
'4.0.92' is Trilio 4.0 build version. Container tag: 4.0.92-rhosp16 '4.0.115' is Trilio 4.0 SP1 build version. Container tag: 4.0.115-rhosp16
There are three registry methods available in RedHat Openstack Platform.
Remote Registry
Local Registry
Satellite Server
Remote Registry
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_osp16.yaml with container urls for:
Trilio Datamover container
Trilio Datamover api container
Trilio Horizon Plugin
trilio_env_osp16.yaml will be available in triliovault-cfg-scripts/redhat-director-scripts/
Local Registry
Follow this section when 'local registry' is used on the undercloud.
In this case it is necessary to pull the Trilio containers to the undercloud registry. Trilio provides shell scripts which will pull the containers from 'registry.connect.redhat.com' to the undercloud and updates the trilio_env_osp16.yaml with the values for the datamover and datamover api containers.
The script assumes that the undercloud container registry is running on port 8787. If the registry is running on a different port, the script needs to be adjusted manually.
The changes can be verified using the following commands.
Satellite Server
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_osp16.yaml with container urls for:
Trilio Datamover container
Trilio Datamover api container
Provide environment details in trilio-env_osp16.yaml
Provide backup target details and other necessary details in the provided environment file. This environment file will be used in the overcloud deployment to configure Trilio components. Container image names have already been populated in the preparation of the container images. Still it is recommended to verify the container URLs.
The following information are required additionally:
Network for the datamover api
Backup target type {nfs/s3}
In case of NFS
list of NFS Shares
NFS options
In case of S3
s3 type {amazon_s3/ceph_s3}
Access key
Secret key
S3 Region name
S3 Bucket name
S3 Endpoint URL
S3 SSL Enabled {true/false}
Deploy overcloud with trilio environment
Use the following heat environment file and roles data file in overcloud deploy command:
trilio_env_osp16.yaml
roles_data.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:
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.
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.
On Compute node
Make sure Trilio datamover container is in running state and no other Trilio container is deployed on compute nodes.
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.
Configure Trilio Appliance
Once RHOSP16.0 Installation steps have completed successfully, follow the instructions below to now configure the Trilio Appliance
Change the nova user id on the Trilio Nodes
In RHOSP, 'nova' user id on nova-compute docker container is set to '42436'. The 'nova' user id on the Trilio nodes need to be set the same. Do the following steps on all Trilio nodes:
Download the shell script that will change the user id
Assign executable permissions
Execute the script
Verify that 'nova' user and group id has changed to '42436'
Run the Trilio configurator
Follow this documentation to configure Trilio Appliance.
Change the workloadmgr.conf to use the right mountpoint
It is necessary to first configure the Trilio appliance, before the steps of this section can be done.
RHOSP16 is using a different mount point in its datamover containers than other Openstack distribution. It is necessary to adjust the mountpoint of the Trilio Nodes to match this. If the mountpoints are not getting aligned, will files created by the datamover and read by the Trilio appliance not match in their paths and backup and restore processes will fail.
Please follow these steps to align the mountpoints:
Edit /etc/workloadmgr/workloadmgr.conf file
Set parameter 'vault_data_directory' to '/var/lib/nova/triliovault-mounts'
create the directory for the mountpoint
assign the created directory to nova:nova
unmount the old mountpoint
Update the Trilio configurator
Restart the Trilio services
Verify the mountpoint has been configured correctly
Troubleshooting for overcloud deployment failures
Trilio components will be deployed using puppet scripts.
In case of the overcloud deployment failing does the following command provide the list of errors:
Further commands that can help identifying any errors.
In case of the trilio datamover api container is failing to start or stuck in restart, check these logs:
In case of Trilio datamover container failing to start or being stuck in restart, check these logs:
Cinder backend is Ceph - additional steps
Add Ceph details to configuration file
If Cinder backend is Ceph it is necessary to manually add the ceph details to tvault-contego.conf on all compute nodes.
The file can be found here:
/var/lib/config-data/puppet-generated/triliodm/etc/tvault-contego/tvault-contego.conf
Add the following information:
The same block of information can be found in the nova.conf file.
Restart the datamover container
