d. Create the
fence.ccs
file. This file contains information required for the fencing
method(s) used by the GFS cluster. The file should look like the following:
fence_devices {
apc {
agent = "fence_apc"
ipaddr = "10.0.1.10"
login = "apc"
passwd = "apc"
}
}
e. The GFS license file should have been downloaded with the GFS RPMs. Rename the
license file to
license.ccs
and move it into the CCS directory:
n01#
mv license.ccs /root/alpha
6. Create the CCS Archive on the CCA Device.
Note
This step only needs to be done once and from a single node. It should not be performed every
time the cluster is restarted.
Use the
ccs_tool
command to create the archive from the CCS configuration files:
n01#
ccs_tool create /root/alpha /dev/pool/alpha_cca
Initializing device for first time use... done.
7. Start the CCS daemon (
ccsd
) on all the nodes.
Note
This step must be performed each time the cluster is rebooted.
The CCA device must be specified when starting
ccsd
.
n01#
ccsd -d /dev/pool/alpha_cca
n02#
ccsd -d /dev/pool/alpha_cca
n03#
ccsd -d /dev/pool/alpha_cca
lcksrv#
ccsd -d /dev/pool/alpha_cca
8. At the lock server node (
lcksrv
), start the LOCK_GULM server:
lcksrv#
lock_gulmd
