5. Create CCS files.
a. Create a directory called
/root/alpha
on node
n01
as follows:
n01#
mkdir /root/alpha
n01# cd /root/alpha
b. Create the
cluster.ccs
file. This file contains the name of the cluster and the name of
the nodes where the LOCK_GULM server is run. The file should look like the following:
cluster {
name = "alpha"
lock_gulm {
servers = ["lck01", "lck02", "lck03"]
}
}
c. Create the
nodes.ccs
file. This file contains the name of each node, its IP address, and
node-specific I/O fencing parameters. The file should look like the following:
nodes {
n01 {
ip_interfaces {
eth0 = "10.0.1.1"
}
fence {
power {
apc {
port = 1
}
}
}
}
n02 {
ip_interfaces {
eth0 = "10.0.1.2"
}
fence {
power {
apc {
port = 2
}
}
}
}
n03 {
ip_interfaces {
eth0 = "10.0.1.3"
}
fence {
power {
apc {
port = 3
}
}
}
}
lck01 {
ip_interfaces {
eth0 = "10.0.1.4"
}
fence {
power {
apc {
port = 4
