Additional disk space may be needed when the environment is extensive in size.
Resolution
To add additional disk space to the vRealize Network Insight 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 vRealize Network Insight 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.
Additional Information
In case troubleshooting is required, the cron job script location is /home/ubuntu/build-target/common-utils/cron.5m/run-expandpart.sh. The related log file can be found at /home/ubuntu/logs/disk_util.log.
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 vRealize Network Insight has detected the new disk and added it to the /var partition. DO NOT remove any disk added under any circumstance.
