I was unable to create RAID1 PVs under 0.9.1_beta2 (RH 7.0.90 - Fisher), so I 
used some raw partitions. I upgraded to 0.9.1_beta4 (which fixed the OOPS or 
boot - great!) and have managed to create and add the RAID PV.

I'd like to remove the old PVs, and the empty one was `vgreduce's OK, but I 
can't pvmove the data from the old one.

# pvmove /dev/hda9 
pvmove -- moving physical extents in inactive volume group "vg01"
pvmove -- WARNING: moving of active logical volumes may cause data loss!
pvmove -- do you want to continue? [y/n] y
pvmove -- ERROR "pv_move_pe(): PE lock" pv_move_pe

pvmove -- ERROR "pv_move_pe(): PE lock" moving physical extents

# 

Any ideas ?

I was hoping to HACK it pro tem, and create new LVs by specifying the PVs to 
use, but this too failed:

# lvcreate -L 50M -n repl vg01 /dev/md8
lvcreate -- rounding up size to physical extent boundary "52 MB"
lvcreate -- couldn't read physical volume "/dev/md8"

# 

Should this work ? (the man page doesn't describe `[PhysicalVolumePath...]'


Not directly LVM, but if I run out of inodes, is there some way to extend an 
ext2 FS so that the ratio of inodes/block is higher than the original FS ?
