To recover from a corrupted quorum log or quorum disk

  1. If the Cluster service is running, open Computer Management.
  2. In the console tree, double-click Services and Applications, and then click Services.
  3. In the details pane, click Cluster Service.
  4. On the Action menu, click Stop.
  5. Repeat steps 1, 2, 3, and 4 for all nodes.
  6. If you have a backup of the quorum log, restore the log by following the instructions in "Backing up and restoring server clusters" in Related Topics.
  7. If you do not have a backup, select any given node. Make sure that Cluster Service is highlighted in the details pane, and then on the Action menu, click Properties.
  8. Under Service status, in Start parameters, specify /fixquorum, and then click Start.

  9. Switch from the problematic quorum disk to another quorum resource.

    For more information, see "To use a different disk for the quorum resource" in Related Topics.

  10. In Cluster Administrator, bring the new quorum resource disk online.

    For information on how to do this, see "To bring a resource online" in Related Topics.

  11. Run Chkdsk, using the switches /f and /r, on the quorum resource disk to determine whether the disk is corrupted.

    For more information on running Chkdsk, see "Chkdsk" in Related Topics.

    If no corruption is detected on the disk, it is likely that the log was corrupted. Proceed to step 12.

  12. If corruption is detected, check the System Log in Event Viewer for possible hardware errors.

    Resolve any hardware errors before continuing.

  13. Stop the Cluster service after Chkdsk is complete, following the instructions in steps 1 - 4.
  14. Make sure that Cluster Service is highlighted in the details pane. On the Action menu, click Properties.

    Under Service status, in Start parameters, specify /resetquorumlog, and then click Start.

    This restores the quorum log from the node's local database.

    Important

  15. Restart the Cluster service on all other nodes.
