To review, /dev/md0 is a RAID1 of /dev/hde1 /dev/hdg1.
When I originally cerated the volume group, I created it on the RAID device
# vgcreate localvg /dev/md0
I'm not sure whether the display from lvmdiskscan above is normal and expected
when using LVM on top of a software RAID device.
Well here's some more information on my setup. I've got my root fs
and a swap "volume" as logical volumes on a raid1 array
$ cat /proc/mdstat
Personalities : [raid1]
md0 : active raid1 sda5[0] sdb5[1]

I'm a little suspicious about those lines in your output:
/dev/hde1 [ 111.79 GB] LVM physical volume
Found duplicate PV 7LOs90S2Ff8W7Tq8ZGRsT41lphbExsLh: using /dev/hdg1
not /dev/hde1
/dev/hdg1 [ 111.79 GB] LVM physical volume
To me this looks like, instead of building a raid array with two
physical partitions and then making that a PV, you tried to make a
raid array from two LVM PVs.
My setup has LVM on top of raid. I know that way works, I'm not sure
whether or not raid on top of LVM does.
