[linux-lvm] FC6: pvmove gives "device-mapper: reload ioctl failed: Invalid argument"

[Ask Bjørn Hansen]

Hi,

I'm trying to use pvmove to move a vg from one pv to another.

This is with whatever is the latest version of the kernel and lvm  
tools on FC6,

[root at zaphod /]# lvm version
   LVM version:     2.02.06 (2006-05-12)
   Library version: 1.02.07 (2006-05-11)
   Driver version:  4.7.0
[root at zaphod /]# uname -a
Linux zaphod 2.6.18-1.2849.fc6 #1 SMP Fri Nov 10 12:34:46 EST 2006  
x86_64 x86_64 x86_64 GNU/Linux

The "rbig" volume group is on both /dev/13 (full) and /dev/md8 (same  
size, empty) and a few others.

[root at zaphod /]# pvmove -v /dev/md13 /dev/md8

pvmove --abort sometimes locks up the lvm subsystem (or the device- 
mapper, I've no idea how it works) requiring a reboot.  Sometimes it  
seems to work and lets me try the pvmove again.

Any ideas?
