Hmm, I did it successfully not long ago.

Drive link. Bad idea. You could have simply added them to a existing VG=20

No, that's not a problem.
So, if I got it right, you used the drivelink feature to create one big=20
device, and then put logical volumes on top of that? In this case, yes, you=
would have to backup and start from scratch.
But, I think I wrote it in an earlier thread: The fact that EVMS is=20
currently unmaintained doesn't mean it stops working. So as long as it=20
works fine for you the way it's setup now, there is no reason for you to=20
And I won't do so either. The reason I did it some month ago was that I=20
changed distribution on a slow machine (Gentoo->Ubuntu). Since Ubuntu's=20
install CDs didn't provide EVMS, I first switched all volumes to normal LVM=
ones, then installed Ubuntu, installed EVMS and converted back.
