Running a manual repair

Run a manual repair operation on tables in a keyspace. Use the Repair option in the Node Administration area of OpsCenter Monitoring. Do not run a manual repair if the Repair Service or NodeSync Service is active.

1. Click cluster name > Nodes.
2. In the List view, select a node.
3. Click Repair from the main actions bar.

   

   Tip: The Repair option is also available from the Actions menu in the Node Details dialog.
   The Choose Repair Options dialog appears.

   

4. Select one or more or all tables within a keyspace. Click the keyspace name to select all its tables.
   Manual repairs can only be performed on a single keyspace per operation.
5. Optional: If applicable to your environment, select Only use nodes in the same datacenter for the repair. This option is analogous to using the -local, --in-local-dc option for nodetool repair. Otherwise, nodes in other datacenters within a multi-DC environment are used in the repair as appropriate.
6. Optional: If applicable, select Only repair this node's primary range. This option is analogous to using the -pr, --partitioner-range option of nodetool repair.
7. Optional: To run the repair simultaneously on all replicas for the node's range, select Fully concurrent repair. This option is analogous to using the -full, --full option of nodetool repair.
   Note: Only select the fully concurrent option if using SSDs (solid-state drives) or do not have concerns with heavy disk I/O.
8. Click Repair.
   The Run Repair? dialog appears and warns that the repair operation might have a significant impact on system performance.

   

9. Click Run Repair.
   A message in the top banner indicates the operation is in progress. Click the Show Details link to view the progress in the Activities page General tab. The banner message indicates when the operation is done.
