Workload Import & Migration
Last updated
Last updated
Each Trilio Workload has a dedicated owner. The ownership of a Workload is defined by:
Openstack User - The Openstack User-ID is assigned to a Workload
Openstack Project - The Openstack Project-ID is assigned to a Workload
Openstack Cloud - The Trilio Serviceuser-ID is assigned to a Workload
Openstack Users can update the User ownership of a Workload by modifying the Workload.
This ownership secures, that only the owners of a Workload are able to work with it.
Openstack Administrators can reassign Workloads or reimport Workloads from older Trilio installations.
Workload import allows to import Workloads existing on the Backup Target into the Trilio database.
The Workload import is designed to import Workloads, which are owned by the Cloud.
It will not import or list any Workloads that are owned by a different cloud.
To get a list of importable Workloads use the following CLI command:
--project_id <project_id> List workloads belongs to given project only.
To import Workloads into the Trilio database use the following CLI command:
--workloadids <workloadid> Specify workload ids to import only specified workloads. Repeat option for multiple workloads.
The definition of an orphaned Workload is from the perspective of a specific Trilio installation. Any workload that is located on the Backup Target Storage, but not known to the TrilioVualt installation is considered orphaned.
Further is to divide between Workloads that were previously owned by Projects/Users in the same cloud or are migrated from a different cloud.
The following CLI command provides the list of orphaned workloads:
Running this command against a Backup Target with many Workloads can take a bit of time. Trilio is reading the complete Storage and verifies every found Workload against the Workloads known in the database.
Openstack administrators are able to reassign a Workload to a new owner. This involves the possibility to migrate a Workload from one cloud to another or between projects.
Reassigning a workload only changes the database of the target Trilio installation. When the Workload was managed before by a different Trilio installation, will that installation not be updated.
Use the following CLI command to reassign a Workload:
A sample mapping file with explanations is shown below:
--migrate_cloud {True,False} Set to True if you want to list workloads from other clouds as well. Default is False.
--generate_yaml {True,False} Set to True if want to generate output file in yaml format, which would be further used as input for workload reassign API.
--old_tenant_ids <old_tenant_id> Specify old tenant ids from which workloads need to reassign to new tenant. Specify multiple times to choose Workloads from multiple tenants.
--new_tenant_id <new_tenant_id> Specify new tenant id to which workloads need to reassign from old tenant. Only one target tenant can be specified.
--workload_ids <workload_id> Specify workload_ids which need to reassign to new tenant. If not provided then all the workloads from old tenant will get reassigned to new tenant. Specifiy multiple times for multiple workloads.
--user_id <user_id> Specify user id to which workloads need to reassign from old tenant. only one target user can be specified.
--migrate_cloud {True,False} Set to True if want to reassign workloads from other clouds as well. Default if False
--map_file Provide file path(relative or absolute) including file name of reassign map file. Provide list of old workloads mapped to new tenants. Format for this file is YAML.
