Issue/Introduction
This article explains how to add additional disk space to a Aria Operations for Networks Platform node.
Aria Operations for Networks may stop working when the disk is full.
When the /var partition is more than 89% utilized, samza/flink containers services will stop to prevent the disk from going out of space.
When disk utilization is at 82% on Aria operations for Network Appliances, adding more disk space can help in preventing any service interruption.
Environment
VMware vRealize Network Insight 6.9 Aria Operations for Networks 6.10.0 Aria Operations for Networks 6.11.0 Aria Operations for Networks 6.12.0 Aria Operations for Networks 6.13.0 Aria Operations for Networks 6.14.0
Cause
Additional disk space may be needed when the environment is extensive in size.
Resolution
To add additional disk space to the Aria Operations for Networks nodes, perform the actions below. Note: Review the Impact / Risks section before proceeding.
Log into vCenter via the web-client with sufficient privileges.
Right-Click the Platform VM and click Edit Settings.
Add a disk with size of 500GB.
Wait for 10-15 minutes for Aria Operations for Networks (vRNI) to detect the disk and add it to the /var partition.
A cron job runs every 5 minutes and checks for any new disks added to the VM, then automatically expands the required partition.

Impact/Risks:
DO NOT complete the resolution steps while the nodes are in a powered off state. DO NOT expand the existing disks presented to the VM, instead add a new disk. DO NOT reboot any nodes until after Aria Operations for Networks (vRNI) Appliance(s) has detected the new disk and added it to the /var partition. DO NOT remove any disk added under any circumstance.
