Recently we have discovered that the disk of a select few probes have filled up, causing scanning to halt for those specific probes. Partners affected have been informed regarding these probes and we will keep on monitoring this and inform you where needed.
The probes that were affected have been generated before January 2023 and will only have a total of 20GB of disk space. Due to scanner extensions and the availability of many new vulnerability plugins over the last few years, the 20GB disk space proofs to not be sufficient enough anymore to provide reliable scanning in the near future. Note that since January 2023 we ship all our probes with 40GB of diskspace, which is ample space for future proof usage.
To prevent any issues and to future proof the probes, we would like to proactively expand the disk of all probes. We have developed some automated processes that will expand the disks and filesystem of probes automatically once the disk of the
Virtual Machine itself has been expanded. There is however a manual task that needs to performed by you - the partner - to expand the disk on the probe’s Virtual Machine side.
We will contact you directly via mail regarding the specific customer probes that still only hold 20GB of total disk space, so these can be expanded to 40GB.
To give you a heads-up, we will provide you a few examples below on how you can expand the disk of a Virtual Machine on a Hyper-V or VMware ESXi environment. On other hypervisor or cloud environments the steps are most likely very similar, but the steps, menu’s or commands might slightly differ.
NOTE: In many scenarios the changes that need to be applied don’t work without shutting down the probe’s Virtual Machine. We therefore recommend to temporarily shut down the probe’s Virtual Machine, perform the changes and start the probe’s Virtual Machine again.
Hyper-V In the Hyper-V Manager select the Virtual Machine en click the right mouse button and select Settings. Open IDE Controller 0 and select Hard Drive, after which the following overview appears:
Locate the Virtual hard disksection and click on Edit. A new window appears where you select Choose Action and Expand:
Click Next and fill in the new total disk space, we recommend at least 40 GB:
Click on Finish and start the Virtual Machine again.
VMware ESXi In the VMware ESXi web interface browse to Virtual Machines. Locate the probe’s Virtual Machine and open the overview. Click on Edit and
a new window like below will appear:
Locate Hard disk 1 in the new window and change the value from 20 to 40 to expand
the disk to a total of 40GB. Click on Save to apply the changes, after which you can start the probe’s Virtual Machine again.
Kind regards, On behalf of the Guardian360 team,
Jan Martijn Broekhof Managing Director.
