vCenter Server disk partitions on Windows or Linux are at 100%
This is due to previously gathered support bundles in the following locations.
vCenter Server Appliance:/etc/vmware-vpx/docRoot/diagnostics
vCenter on Windows:C:\ProgramData\VMware\vCenterServer\cfg\vmware-vpx\docRoot\diagnostics
Manual deletion for support bundles in the previously notated directories is required. After this deletion, there should be space on the partition.
