vCenter 6.7 - How to decrease VMDK size?

Hello folks,

How to safely shrink one of the vCenter disks? I know how to increase the space, well described process, but there is nothing about reducing the drive size.

/dev/mapper/seat_vg-seat                  1.4T  2.2G  1.4T   1% /storage/seat

We've upgraded to 6.7 from 6.5, we had only one options to choose xLarge storage options....the results is above, we ended up with 1.4TB disk for the SEAT.

There is a bug and vCenter support confirmed that PR has been filled with engineering, but they are helpless how to fix this, they recommended to install a new v Center and migrate everything....

I don't want to do that....now, my case has been moved to operation and they gave me a generic procedure how to decrease vmdk size, but no specifics regarding vCenter, I don't want to break anything!

Thanks!

Mario
