Note
Depending on the way the OS is deployed, it may be necessary to
change the server’s profile to match the network configuration of the
server to be exactly the same as it was at the time of backup.
3. Disable the NetworkManager if you have installed NetworkManager on the system. NetworkManager will
not work with cluster.
a. Check if the NetworkManager is installed:
service NetworkManager status
b. Disable the NetworkManager:
service NetworkManager stop
c. Turn off the NetworkManager:
chkconfig NetworkManager off
4. Export the Quorum disk, the KVM Private Cloud appliance physical disk and the Images repository disk to
the newly installed hosts.
5. Rescan the disks using the following command on both of the nodes:
echo “1” > /sys/class/fc_host/host1/issue_lip
echo “1” > /sys/class/fc_host/host2/issue_lip
6. Edit the /etc/sysctl.conf to enable the ipv4 forward using the following command on both of the
nodes:
net.ipv4.ip_forward = 1
7. Copy the files listed in the backup list to the newly installed hosts from its backup copy.
Note
Recover and restart iptables from a backup if the firewall is set
up.
8. Update multipath configuration in /etc/multipath.conf (update the WWID for the new disks) in both
nodes.
9. If the rgmanager is set to ON in chkconfig, set it to OFF before rebooting the system on both nodes. This
prevents the rgmanager from auto-starting after system reboot.
10. Reboot the nodes.
11. Create a Quorum disk called “clqdisk” on only one of the hosts in the cluster.
mkqdisk –c /dev/mapper/isc_quorum –l clqdisk
Enter “y” for the message.
