After I recovered my cluster and all shared disks, the cluster service will not start. Why won’t it start and how can I get it started?
The cluster service may not start because the disk signature on the Quorum disk is different from the original signature. If you have the Microsoft 2000 Resource Kit use Dumpcfg.exe or Clusterrecovery from the Microsoft 2003 Resource Kit to replace the disk. For example, type:
dumpcfg.exe /s 12345678 0
Replace 12345678 with the disk signature and replace 0 with the disk number. You can find the disk signature and the disk number in the event log.
If you do not have the Microsoft 2000 Resource Kit, you can use -Fixquorum to change the Quorum disk signature.
See Changing the Quorum disk signature.
