Building an HA Cluster Configuration
Preparing Your Systems
Chapter 5 155
Next is the BONDING_SLAVE. This tells ifup which ethernet devices to
enslave to bond0. So if you wanted to bond four ethernet devices you
would add:
BONDING_SLAVE2='eth2'
BONDING_SLAVE3='eth3'
NOTE Use ifconfig to find the relationship of eth IDs and the MAC address.
For more networking information on bonding, see
/usr/src/linux<kernel_version>/Documentation/networking/bond
ing.txt.
Restarting Networking
Restart the networking subsystem. From the console of either node in the
cluster, execute the following command on a SUSE system:
/etc/init.d/network restart
NOTE It is better not to restart the network from outside the cluster subnet, as
there is a chance the network could go down before the command can
complete.
If there was an error in any of the bonding configuration files, the
network might not function properly. If this occurs, check each
configuration file for errors, then try to restart the network again.
Setting up a Lock LUN
The lock LUN requires a partition of one cylinder of at least 100K
defined (via the fdisk command) as type Linux (83). You will need the
pathnames for the lock LUN as it is seen on each cluster node. On one
node, use the fdisk command to define a partition of 1 cylinder, type 83,
on this LUN. Here is an example:
Respond to the prompts as shown in the following table to set up the lock
LUN partition:
