Following the success of creating the first node of the REDFERN cluster (REDFERN1), I went ahead with the creation of the second node (REDFERN1).
In general, I followed the same procedure as described in Build REDFERN1 on Victoria.
In order to avoid any conflicts over the VNC console, I shutdown REDFERN1 as follows:
Instead of using xl list to find the domain id of REDFERN1, before issuing the xl shutdown command, I fold these two (2) steps into one (1).
As for REDFERN1, I created a 50G disk for use by the operating system for REDFERN2 as follows:
ddbs=1G count=50 if=/dev/zero of=/OVS/running_pool/REDFERN/redfern2/root_disk &

Using the example in Set Up XEN Network, I ran the following script, on REDFERN1, to populate the device descriptions for the four (4) Ethernet NICs:
cd /etc/sysconfig/network-scripts for iface in 0 1 2 3 do nw=$(((iface + 1))) nic=$(((18 + iface))) ifacename=eth${iface} uuid=$(uuidgen) hwaddr=$(printf "00:16:3e:00:00:%0.2X" ${nic}) # ==== Create Interface cat <<DONE >ifcfg-${ifacename} # ----------------------------------------------------------------------------- # NIC ${ifacename} # Generated $(date +"%F %T") # ----------------------------------------------------------------------------- # Device identification DEVICE="${ifacename}" UUID="${uuid}" HWADDR="${hwaddr}" # Device options BOOTPROTO="static" TYPE="Ethernet" ONBOOT="yes" DELAY="0" NM_CONTROLLED="no" # IPV4 Networking IPADDR="192.168.${nw}.141" NETMASK="255.255.255.0" GATEWAY="192.168.1.1" # DNS DNS1="192.168.1.252" DNS2="192.168.1.1" PEERDNS="yes" DOMAIN="yaocm.id.au" DONE doneThen I brought this NICs up as follows:
ifup eth0 ifup eth1 ifup eth2 ifup eth3ping confirmed connectivity on both REDFERN2 and VICTORIA:
Because I did not set up networking during OEL7 installation, the hostname was left as localhost.hostname. To rectify this, I used the following command:
hostnameredfern2.yaocm.id.au
And I updated /etc/hostname.
I started REDFERN1 and made a similar change there as well.
