Hi @gixxerdaveneo. As this is not PVE-specific, there are many discussions about this situation on the net. A quick Google search brings up:
https://forums.centos.org/viewtopic.php?t=76660
https://serverfault.com/questions/912972/sectors-which-is-smaller-than-corresponding-pv-size-error

I'd recommend viewing these and other articles and proceeding very carefully. Making a wrong move can lead to data loss.

Good luck
