In VMware Aria Operations for Networks, you can add additional disk space to a VMware Aria Operations for Networks Platform or Collector node.

If the disk usage on the Platform or Collector are high, adding more disk space helps you prevent any unwanted service interruption.
Note: Do not expand the existing disks available in the VM. You must always add a new disk in the VM.
Note: Do not reboot any VMs until VMware Aria Operations for Networks detects the new disk and the new disk space is added in the /var partition.

Prerequisites

Ensure that the nodes are in the power-on state, and you have the correct privileges.

Procedure

  1. Log in to VMware vCenter using the web client with correct privileges.
  2. Right-click the VM, and click Edit Settings.
  3. Add a disk of required size.
    A cron job runs every 5 minutes and checks for any new disks added to the VM, then automatically expands the required partition.

What to do next

Wait for 10-15 minutes for VMware Aria Operations for Networks to detect the disk, and then check and ensure that the additional disk size is visible in the /var partition.

In case troubleshooting is required, the cron job script location is: /home/ubuntu/build-target/common-utils/cron.5m/run-expandpart.sh. You can find the related log file at /home/ubuntu/logs/disk_util.log.
