A. Normally, you should allow Chkdsk to run to avoid corruption and identify any potential problems. If you have a disk failover between nodes enabled, however, there may be times you need to stop it. You can stop Chkdsk from executing by modifying the cluster disk resource's properties and setting the value of DiskRunChkDsk to 4, as detailed at this MSDN site. To make the modification, enter the following at a command prompt.

cluster /cluster:<cluster> res "<disk name>" /priv DiskRunChkDsk=4
