You have resized the SpanVA Disk Allocation by increasing it to 1TB in the virtualization software, but the SpanVA Interface > Settings disk allocation still shows the "Currently allocated size" is only 128 GB. That is despite the fact that the actual disk size in the Virtual Hardware details is correct.
Virtualization software configuration:
CASB Audit
SpanVA
A second disk was added, which is not supported in SpanVA.
Instead of adding a second disk, extend the size of the original (primary) disk.
