pvmove: ERROR "pv_read(): device major number"

Hi,

using Kernel 2.4.18+XFS 1.1+LVM 1.1rc2+VFS lock I want to move an LV to a different PV to move the currently unprotected data to a mirrored device. I entered the following line as root (no su -):

	# pvmove --version
	pvmove: Logical Volume Manager 1.1-rc1
	Heinz Mauelshagen, Sistina Software  15/03/2002 (IOP 10)

	# pvmove /dev/vg00/lv_swap /dev/hda1 /dev/md0
	pvmove -- ERROR "pv_read(): device major number" reading source physical volume "/dev/vg00/lv_swap"

The mentioned LV is not in use.

Same problem with a native disk partition:

	# pvmove /dev/vg00/lv_swap /dev/hda1 /dev/hdc1         
	pvmove -- ERROR "pv_read(): device major number" reading source physical volume "/dev/vg00/lv_swap"

The root file system is on an LV, too.

What's going on here?

Stephan

Stephan,

you seem to run LVM 1.1-rc1 as pvmove states which had a flaw checking used devices.

Could you please either use LVM 1.1-rc2 or LVM 1.1 from top of CVS (see instructions at www.sistina.com IRT CVS repository on how to check that out) and tell me, if that works.

Please keep in mind that LVM 1.1 is unstable development software not meant for production systems!

Hello, Heinz,

I've just tried it with 1.1-rc2 without success:

	# ./pvmove --version
	pvmove: Logical Volume Manager 1.1-rc2
	Heinz Mauelshagen, Sistina Software  23/04/2002 (IOP 10)

	# ./pvmove /dev/vg00/lv_swap /dev/hda1 /dev/hdc1
	pvmove -- ERROR "pv_read(): device major number" reading source physical volume "/dev/vg00/lv_swap"

I built the LVM tools statically to avoid interference with installed packages (Debian Woody).

Same problem with LVM 1.0.4 using LVM 1.0.4 tools.

Stephan

Oh, oh... the problem is sitting in front of the screen... I forgot giving '-n' before the LV... Sorry.

Stephan
