When attempting to apply a patch to VMware Aria Automation 8.18.x, the precheck task fails, and the following Recommendations message is displayed:
Recommendations
1. Disk space on root partition (/) on VM Disk 1 on node:
<Hostname> should have atleast 30 GB of free disk space
to perform upgrade and work normally. To satisfy the requirement
increase root partition (/) on VM Disk 1 WITHOUT POWERING OFF THE
VA. Then run 'vracli disk-mgr resize' on the VMware Aria Automation VA
from the command shell.VMware Aria Automation 8.18.x
This error occurs due to insufficient available disk space on the root partition (/dev/sda).
If you are unable to clear enough unnecessary files from the root partition to meet the 30 GB free space requirement, you must increase the disk size.
Note: It is strongly recommended to create a snapshot or backup of the Aria Automation appliance before proceeding.
Using the vSphere Client, navigate to the Aria Automation appliance's Edit Settings menu and expand the size of the virtual disk.
Log in to the Aria Automation appliance via SSH as the root user.
Verify the current disk space by running the following command: df -h /
Execute the following command to apply the new disk size: vracli disk-mgr resize
Wait approximately 3 minutes, then run df -h / again to confirm that the available capacity has successfully increased.
