[linux-lvm] more pvmove problems

I've tried to search online, and found some mentions of a patch, but I
can't be sure if it applies to my case.
LVM 1.0.8 from source
One of my drives started reporting read errors, so I got a new one, and
wanted to replace it. Since I was replacing a 200G drive with a 250G, I
too the chance to get rid of the 30G drive in there too.
Added the new drive, created a PV on it, added it to the VG and moved
the 30G drive to it with pvmove, no problem. Then I started moving the
200G drive over.
Had an error early in the process, so I had to retry with the -i flag.
It kept failing, so after reading up in the man page, I was able to copy
the rest of the PV using the -n flag:
pvmove -v -i -n medialv:61-6076 /dev/hde /dev/hdh
36 hours later, the process finished. Now I figured I still need to
move the first 60 PEs. But whatever I try, I can't get pvmove to work.
Here's what pvscan reports (hde is the drive I'm trying to retire):
pvscan -- reading all physical volumes (this may take a while...)
pvscan -- ACTIVE PV "/dev/hdg" of VG "mediavg" [189.88 GB / 0 free]
pvscan -- ACTIVE PV "/dev/hdh" of VG "mediavg" [233.72 GB / 17.84 GB free]
pvscan -- ACTIVE PV "/dev/hde" of VG "mediavg" [189.88 GB / 187.97 GB free]
pvscan -- inactive PV "/dev/hdd" is in no VG [27.96 GB]
pvscan -- ACTIVE PV "/dev/hdb" of VG "mediavg" [74.47 GB / 0 free]
pvscan -- total: 5 [716.10 GB] / in use: 4 [688.14 GB] / in no VG: 1 [27.96 GB]
And here's what I get when I try "pvmove -vv /dev/hde":
pvmove -- checking name of source physical volume "/dev/hde"

zsh: exit 23 sudo pvmove -vv /dev/hde
Any suggestions? At this point, I'm willing to lose some data off the
drive, just so I can remove it and remount my partition.
If there's any other information I can provide, I'd be happy to.
