There's some stuff written to the MBR/EBR containing stuff such as the 
drive letter and also in the case of the original JFS, info about 
volumes that span partitions, something that isn't really recommended. 
You can grow but not shrink a non-bootable JFS volume.

That's the recommended way. The only outside tool that handles the LVM 
info is DFSee (dfsee.com) and even that recommends not doing it.
You will know if you got the alignment right if lvm (minilvm) accepts 
the partition.
