Installing oVirt 3.1 and glusterfs using either NFS or Posix (Native) File System Node Install


Node Install

So lets begin by installing the a node. The node install is pretty standard but there are a few very important steps that have to be done or it wont work correctly. All the issues I have found have been put into bugzilla. Before you begin your node install please make sure you have the engine setup correctly as outlined in Engine Install.

  1. Do a base (Minimal) install of your chosen OS.
  2. Upgrade to the lastest packages.
    yum -y upgrade
  3. Setup a glusterfs repo this repo was created by the same person who does the 3.2.5 packages in Fedora/EL6.
    • For RHEL/CentOs/Scientific Linux 6.2

      wget -P /etc/yum.repos.d/
    • For Fedora 17

      wget -P /etc/yum.repos.d/
  4. Setup the oVirt repo you intentend to use.
    • For RHEL/CentOs/Scientific Linux 6.2

      wget -P /etc/yum.repos.d/
    • For Fedora 17

      wget -P /etc/yum.repos.d/
  5. Now lets install some packages
    yum clean all
    yum install vdsm vdsm-cli vdsm-gluster

Now lets get the install ready to join the cluster.

  1. Force NFS to use ver. 3 edit /etc/nfsmount.conf and add.
    [ NFSMount_Global_Options ]
  2. Based on my install the management bridge fails to create most of the time. Here is how I manually create them. The example config files all reside in /etc/sysconfig/network-scripts.
    First we edit /etc/sysconfig/network-scripts/ifcfg-eth0. On your system it might be em0 instead of eth0. Adjust the device line to match what is already there.

  3. Now we create /etc/sysconfig/network-scripts/ifcfg-ovirtmgmt with the following

Now lets return to the engine and add the host into the cluster.

  1. Select the Host tab.
  2. Click New to add a new host.
  3. Name: Enter a Name you want the host to be known as.
  4. Address: Either enter the IP address or URL for the host.
  5. Root Password: Enter the root password for the host
  6. Automatically configure host firewall: Leave it checked
  7. You need to setup your power management settings. Below is a screen shot of my Drac5 settings. Note your 1st node will fail since there isn’t a 2nd node as you can see from the screen shot
  8. This step will take about 5 min a node and will reboot the node. Only add one node at a time I have had weird issue

Repeat for each host. Note you still need to make some changes on each host but because each node needs to talk to each other I suggest setting up all nodes first.
