Configuring a symmetrical cluster

Use the notes.ini setting D10_ENABLE_REPAIR=1 and a Cluster Configuration document to enable a cluster to be symmetrical.

Procedure

  1. Add the following setting to the notes.ini file on each server in the cluster: 
    D10_ENABLE_REPAIR=1
  2. Run the AutoRepair and RepairCleanup tasks at server startup by adding them to the ServerTasks setting in the notes.ini file on each server in the cluster. 
    ServerTasks=Replica,Router,Update,AMgr,Adminp,Sched,CalConn,RnRMgr,AutoRepair,RepairCleanup
    Note: Alternatively:
    • To run AutoRepair on schedule, use the Repair all console command in a Program document.
    • To run RepairCleanup on schedule, use the RepairCleanup task in a Program document.
  3. Each database replica that you monitor must have the same file path, file name, and letter case on all servers in the cluster. To verify that this requirement is met:
    1. Open the Cluster Database Directory database (cldbdir.nsf).
    2. Select the Databases by Replica ID view.
    3. In the File column, verify that each replica shows the same file path, file name, and letter case.
  4. From the Domino® directory of a server in the cluster, click Configuration > Clusters > Configuration.
  5. Click Add Cluster Configuration.
  6. In the Basics tab, select the cluster.
  7. In the Symmetrical Clusters tab, select options:
    OptionDescription
    Maintain symmetry
    • To maintain symmetry for all databases in all folders below the data directory, select All folders.
    • To maintain symmetry for databases in specific folders below the data directory, select Specified subfolders and select the folders.
    Automatic repair
    • To have the repair service replace all missing files detected by AutoRepair in the selected folders, select Fix missing files.
    • To report missing files detected by AutoRepair to log.nsf but not have the repair service replace them, select List missing files in the log.
    • To prevent AutoRepair from running, select Disabled.
    Scan interval Specify how frequently AutoRepair runs, in minutes, to check for missing databases.
    Damaged files
    • To enable damaged databases in monitored folders to be repaired, select Fix damaged files.

      Damaged files that cannot be repaired by Fixup are quarantined with the .pd_bad_<timestamp> extension and the repair service recovers new copies immediately from cluster members.

    • To prevent repairing of damaged files, select Disabled.
    Remove damaged files after Specify the number of days that files remain quarantined before they can be removed by RepairCleanup. Default is 20 days.
  8. Close and save the document.
