If the drive contains existing plots and was deployed without LVM, you can use blocks to convert to LVM first, then shrink the existing volume to make space for the second volume which you then add to a volume group that spans across drives.
@enderTown ever come up with a good way to automatically re-mount all the VHDs after reboot? Seems like I have to go into Disk Management and Action->Attach VHD every time I come back from a windows update.
I did actually! I forgot to update the post - thanks for the reminder. Hereās a quick Powershell script that will mount all VHDXās under a directory:
Perfect! Iām going to give this a try tonight. Itās getting more and more cumbersome as I add more and more drives (and therefore, more and more VHD with whatās left over after plotting)
