For more information about manual repairs, see the corresponding nodetool repair command.

Prerequisites

  • If OpsCenter role-based security is enabled, be sure that the permission for the Repair option in Node Operations is enabled for the appropriate user roles.
  • Disable (admin)Disable (dev) the NodeSync Service and disable the Repair Service if they are running.
    Warning: Do not run a manual repair if the Repair Service or NodeSync Service is active. Manual repairs fail if those services are active.

Procedure

    Choose repair options when running a manual repair in OpsCenter Nodes admin area

  4. Required: 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.
