[linux-lvm] Strange messages on my Fedora Box

[Georges Giralt]

Hi !
The context :
Fedora Core 7 on an X86-64  AMD Athlon 64x2 box.
lvm> version
   LVM version:     2.02.24 (2007-03-19)
   Library version: 1.02.17 (2007-01-29)
   Driver version:  4.11.0
lvm>
Kernel : 2.6.22.1-27.fc7
3 X 160 Gb disks with 4 primary partitions
the 3 last partitions in each disks make 3 VG : vgF32, vgF64 and vg-Ext.
I use LVM mirroring.
The vgF32 vg hold a FC7 32 bits version, vgF64 the FC7 64 bits version 
(the one I use now) and vg-Ext the home and various data.
Today, i ran lvs and get the following message.
I've nothing in the system message file nor in the dmesg ring.
/bott is an md made with the 2 first partitions of the 2 first disks and 
is fine.
Questions :
Is it serious ? What should I do ? How to recover ?
TIA

Mirror staus string is broken in 2.6.22 stable kernel, I hope that fix will be
part of next stable update.

patch exist for some time here
http://www.kernel.org/pub/linux/kernel/people/agk/patches/2.6/editing/dm-raid1-fix-status.patch

If you boot to 2.6.21 kernel, it should work ok, 2.6.23-rc1 has this fix too.
It is only reporting problem for mirrored volumes (in this case).
(But it is breaking pvmove functionallity too.)

Thanks Milan !
I _do_ prefer that.
I'll wait until the code is fixed.
