Upgrade Guide

Configure HP CSA to share filesystem resources to free up disk space (this task is optional). Static filesystem resources, such as images, can be stored on one system and shared by all nodes in the cluster. The following example shows how to share the images directory that is installed with each instance of HP CSA.

HP CSA provides images that are stored in an images directory (for example, %CSA_HOME%\jboss-as-7.1.1.Final\domain\servers\hp-cloud\deployments\csa.war\images$CSA_HOME/jboss-as-7.1.1.Final/domain/servers/hp-cloud/deployments/csa.war/images). From the Cloud Service Management Console, you may also upload images which are saved to the same images directory. You can store these images on a shared filesystem on a network and the images on this single shared filesystem can be used by all nodes in the cluster.

To configure HP CSA to use a shared filesystem to store images, do the following:

  1. Create a shared filesystem on the network. The master and slave nodes must be able to read and write to the shared location.
  2. Map the shared location as a network drive. For example, map S:\CSA on the master node to the shared location.

    Mount the shared location. For example, mount the shared location to /mnt/csa by typing mount -t cifs -o username=<user>, password=<pass> //sharedhost/CSA/ /mnt/csa

  3. Move the %CSA_HOME%\jboss-as-7.1.1.Final\domain\servers\hp-cloud\deployments\csa.war\images$CSA_HOME/jboss-as-7.1.1.Final/domain/servers/hp-cloud/deployments/csa.war/images directory to the shared location (for example, S:\CSA\images/mnt/csa/images).

    Ensure that the mapped mounted images directory is readable and writeable.

  4. Delete the %CSA_HOME%\jboss-as-7.1.1.Final\domain\servers\hp-cloud\deployments\csa.war\images$CSA_HOME/jboss-as-7.1.1.Final/domain/servers/hp-cloud/deployments/csa.war/images directory from the master and slave nodes.

  5. Create a symbolic link to the mapped mountedimages directory. For example, from a command prompt, type the following commands:

    cd %CSA_HOME%\jboss-as-7.1.1.Final\domain\servers\hp-cloud\deployments\csa.war
    mklink /d images "S:\CSA\images"

    cd $CSA_HOME/jboss-as-7.1.1.Final/domain/servers/hp-cloud/deployments/csa.war
    ln -s /mnt/csa/images images

  6. Set the permissions and ownership for the images directory. Type the following:

    cd $CSA_HOME/jboss-as-7.1.1.Final/domain/servers/hp-cloud/deployments/csa.war
    chmod 755 images
    chown csauser:csagrp images
