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



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 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 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 zaphod /]# pvmove -v /dev/md13 /dev/md8

dmesg says:

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?
