Okay.... So I'm reinstalling OMV.
Ran the installer, which is on a 16gb flash drive.... Then I have my target which is a 32gb flash drive. completely clean, no partitions on it...
Attempt to install on it and it goes "Failed to partition the selected disk" says it probably happened because free space is too small to be automatically partitioned.. ITS AN EMPTY 32gb FLASH DRIVE.
So... I tried a different USB port and a totally different 32gb flash drive..... Same problem.
WTF.
I've got to be missing something.
