Environment

VMware Cloud Foundation 4.x

Cause

• Disk space on services-logs partition (/services-logs) on VM Disk 3 on vra node should be  at least 22 GB to perform upgrade and work normally.

Resolution

• Delete the snapshots on all vRA nodes
• Increase the VM DISK 3 size to 22 or above (Do not power off vRA nodes)
• SSH to the appliance.
• Run the command: "vracli disk-mgr resize". The resize procedure will start in up to a minute. Progress could be monitored in the /var/log/disk_resize.log. It is expected to fail while resizing file system for logs disk.
• Run the command: "/usr/sbin/resize2fs /dev/mapper/logs_vg-services--logs"
• Run the command:
• For vRA/vRO 8.0: "rm /var/run/disk_stats"
• For vRA/vRO 8.0.1 and 8.1: "rm /var/vmware/prelude/disk-management/disk_stats"
•  Run the command  "vracli disk-mgr" to verify if new disk space is visible.
• Once the disk is expanded, to recover VRA from the current upgrade, please clean the following files from vRA VM's and retry the upgrade from SDDC manager 

/data/restorepoint
/var/vmware/prelude/upgrade
/var/log/vmware/prelude/upgrade-report-latest*

NOTE: In VCF 4.3 precheck displays the exact failed validation in the SDDC Manager UI.

Alternatively you can also ignore the vra prechecks by changing the below entry in /opt/vmware/vcf/lcm/lcm-app/conf/feature.properties

From
feature.lcm.vra.skip.upgrade.prevalidation=false
to
feature.lcm.vra.skip.upgrade.prevalidation=true

Then  restart lcm service.
