2.3.7 Create a Quorum Disk
The disk quorum allows the cluster manager to determine which nodes in the cluster are dominant using a shared
storage disk (block device) as the medium. Configure a shared virtual drive of at least 10MB for the disk quorum
device.
Perform the following steps to make a disk quorum (qdisk):
1. Create or choose a small capacity Shared VD for the disk quorum by usinging the following command line syntax
at the command line prompt:
mkqdisk -c device -l labelName
The following example assumes a RAID 0 VD with mounting at /dev/sda and mr_qdisk as the quorum disk
name. Enter the following command at the command line prompt:
#mkqdisk -c /dev/sda -l mr_qdisk
2. Check whether qdisk was created at both nodes by entering the following command at the command line
prompt:
#mkqdisk -L
3. Return to the Cluster Management window.
4. Click the Configure tab.
The Quorum Disk Configuration dialog appears, as shown in the following figure.
