Building an HA Cluster Configuration
Setting up the Lock LUN
Chapter 5 155
Command (m for help): p
Disk /dev/sdc: 64 heads, 32 sectors, 4067 cylinders
Units = cylinders of 2048 * 512 bytes
Device Boot Start End Blocks Id System
/dev/sdc1 1 1 1008 83 Linux
Command (m for help): w
The partition table has been altered!
NOTE
• Do not try to use LVM to configure the lock LUN.
• The partition type must be 83.
• Do not create any filesystem on the partition used for the lock LUN.
• Do not use md to configure multiple paths to the lock LUN.
To transfer the disk partition format to other nodes in the cluster use the
command:
sfdisk -R <device>
where <device> corresponds to the same physical device as on the first
node. For example, if /dev/sdc is the device name on the other nodes use
the command:
sfdisk -R /dev/sdc
You can check the partition table by using the command:
fdisk -l /dev/sdc
NOTE fdisk may not be available for SUSE on all platforms. In this case, using
YAST2 to set up the partitions is acceptable.
