58 Maintaining Your Cluster
Recovering From a Corrupt Quorum Disk
The quorum disk maintains the configuration data necessary for recovery
when a node fails. If the quorum disk resource is unable to come online, the
cluster does not start and all of the shared drives are unavailable. If this
situation occurs and you must run chkdsk on the quorum disk, start the
cluster manually from the command line.
To start the cluster manually from a command line prompt:
1
Open a command line window.
2 Select the cluster directory by typing the following:
cd \windows\cluster (for Windows Server 2003)
3
Start MSCS in manual mode (on one node only) with no quorum logging
by typing the following:
Clussvc -debug -noquorumlogging
MSCS starts.
4 Run chkdsk /f on the disk designated as the quorum resource:
a Open a second command line window.
b Ty p e chkdsk /f .
5 After the chkdsk utility completes, stop MSCS by pressing <Ctrl><c> in
the first command line window.
6 Restart MSCS from the Services console:
a Click the Start button and select Programs → Administrative
Tools
→ Services .
b In the Services window, right-click Cluster Service .
c In the drop-down menu, click Start .
d At the command line prompt in either window, type Net Start
Clussvc
.
The Cluster Service restarts.
