4.2. Managing backup nodes¶
4.2.1. vinfra service backup node add¶
Add a list of nodes to the backup cluster:
usage: vinfra service backup node add --nodes <nodes>
--nodes <nodes>- A comma-separated list of node hostnames or IDs
Example:
# vinfra service backup node add --nodes 2f3f6091-0d44-45aa-94e3-ebc2b65c0eeb
+---------+--------------------------------------+
| Field | Value |
+---------+--------------------------------------+
| task_id | affe92f4-0c01-4a06-b91b-4ee0355d9a87 |
+---------+--------------------------------------+
This command creates a task to add the node with the ID 2f3f6091-0d44-45aa-94e3-ebc2b65c0eeb to the backup cluster.
Task outcome:
# vinfra task show affe92f4-0c01-4a06-b91b-4ee0355d9a87
+---------+-------------------------------------------------+
| Field | Value |
+---------+-------------------------------------------------+
| details | |
| name | backend.presentation.abgw.tasks.AssignNodesTask |
| result | |
| state | success |
| task_id | affe92f4-0c01-4a06-b91b-4ee0355d9a87 |
+---------+-------------------------------------------------+
4.2.2. vinfra service backup node list¶
List nodes in the backup cluster:
usage: vinfra service backup node list [--long]
--long- Enable access and listing of all fields of objects.
Example:
# vinfra service backup node list
+--------------------------------------+------------------------+-----------+
| id | host | is_online |
+--------------------------------------+------------------------+-----------+
| 2f3f6091-0d44-45aa-94e3-ebc2b65c0eeb | node003.vstoragedomain | True |
| 74cbd22b-fb1b-4441-ae52-532078c54f9a | node001.vstoragedomain | True |
| eeb06dce-4cfd-4c89-bc7f-4689ea5c7058 | node002.vstoragedomain | True |
+--------------------------------------+------------------------+-----------+
This command lists nodes in the backup cluster.
4.2.3. vinfra service backup node release¶
Release a list of nodes from the backup cluster:
usage: vinfra service backup node release --nodes <nodes>
--nodes <nodes>- A comma-separated list of node hostnames or IDs
Example:
# vinfra service backup node release --nodes 2f3f6091-0d44-45aa-94e3-ebc2b65c0eeb
+---------+--------------------------------------+
| Field | Value |
+---------+--------------------------------------+
| task_id | ea09642c-291c-4df8-87a5-a8958d6308c1 |
+---------+--------------------------------------+
This command creates a task to release the node with the ID 2f3f6091-0d44-45aa-94e3-ebc2b65c0eeb from the backup cluster.
