I use EVMS to manage it and there's some known problem with EVMS and the
kernel simultaneously managing devices under /dev, which you need a
kernel patch to solve.  I can't remember the details.  However, I'm
unwilling to use the LVM command-line tools as I do LVM operations
infrequently enough that I need a more intuitive interface.

Ideas welcome.  I suppose it might be EVMS-related as well, but when I
installed FC3 over an EVMS-enabled Ubuntu, FC3 correctly recognised the
underlying LVM/LVM2 volume groups (and I did the EVMS installation over
the top of FC3), so I can't understand where the issue is.  Essentially
I have 6 hard disk drives in the system:

hda -> no LVM, fine

hdf }
hdg } LVM volume group with several logical volumes
hdh }

sda } LVM2 volume group with several logical volumes
sdb } 

(Can't find the other volume groups now I look, must be another system).
The LVM and LVM2 logical volume groups are all mounted variously under
/home on the FC3 system.  The FC4 system doesn't detect them, and asks
if I want to reinitialise the partition tables on the disks.  When I say
no, it fails at the next stage and asks to restart the computer.
