Hello
I have written a patch that i hope could help on this issue.
it can probably be santized, or rewritten in a better way, but it works
for me as it looks now.
what it does is basicaly.
it checks that it's beeing run preseeded, if not it does nothing.
if the lvm check finds lvm volumes on the disk, it will check that these
volume groups are not spanning multiple disks, if they do it will fail
with the same error as before.
if it finds that the vg is isolated to the disk, preseeded to be erased,
it removes all Logicalvolumes, and VolumeGroups on that disk.
