Maintaining Your Cluster 79
Recovering From a Corrupt Quorum Disk
The quorum disk maintains the configuration data necessary for cluster recovery when a cluster
node fails. If the quorum disk resource is unable to come online, the cluster will not start and all
of the shared drives will be unavailable. If this situation occurs, and you need to run chkdsk on
the quorum disk, you can start the cluster manually from the command line.
To start the cluster manually from a command prompt:
1
Open a command prompt window.
2
Select the cluster folder directory by typing one of the following:
cd \2000\cluster
(for Windows 2000 Advanced Server), or
cd \windows\cluster
(for Windows Server 2003)
3
Start the cluster in manual mode (on one node only) with no quorum logging by typing
the following:
Clussvc -debug -noquorumlogging
MSCS starts.
