Diagnosing unknown repositories
editDiagnosing unknown repositories
editWhen a snapshot repository is marked as "unknown", it means that an Elasticsearch node is unable to instantiate the repository due to an unknown repository type. This is usually caused by a missing plugin on the node. Make sure each node in the cluster has the required plugins by following the following steps:
- Retrieve the affected nodes from the affected resources section of the health report.
- Use the nodes info API to retrieve the plugins installed on each node.
- Cross reference this with a node that works correctly to find out which plugins are missing and install the missing plugins.
