When managing the Stingray Traffic Manager Virtual Appliance you might need to free some space to perform certain tasks. This is usually most visible when performing upgrades where you might be presented with the following message:
Analyzing system: failed ERROR: Not enough space available, need 300000KB, however only xxxxxxKB is available
You can perform the following steps:
Generally, the /logs partition has more free space than the /root partition. You should move the upgrade package (.zpkg) and other temporary files to that partition rather than root.
If all else fails, you can generate a disk space report that lists the largest folders and files on each partition as follows:
# du -ax / | sort -rn | head -50
# du -ax /logs | sort -rn | head -50
Provide this information to Riverbed Technical Support.
Removing Previous Software Versions
When you upgrade the Virtual Appliance, the previous version of the software is retained so that you can revert back to it at any point in time. If you upgrade through a series of minor revisions you might have several older versions of the software still installed. In practice, it is unlikely that you need to retain all of these; having a single version that is known to be good should suffice.
Use the following command to list the software versions that are installed in the currently running partition:
# /opt/zeus/zxtm/bin/rollback --delete
You can safely delete old software versions using this interactive command if you are certain that you will not need to roll-back to them at some point in the future.
In a manner similar to the Stingray Traffic Manager itself, the previous versions of the Stingray Application Firewall are retained following an upgrade. As with the traffic manager you can remove these old software versions to free disk space if you are certain that you will no longer need to roll-back to them.
Version 4.5 or later of the application firewall provides an interface to manage installed versions, the interface can be accessed via the Stingray Traffic Manager administration interface.
Application Firewall > Administration > Cluster Management > Updater > Open Update Center
After logging into the Update Center, use the "Undeploy" action to remove any inactive versions you no longer require.
