Bug#315339: update to lvm2 2.02.05-1 renders striped vg unusable

[Tjeerd Pinkert]

Package: lvm2
Version: 2.02.05-1

Installing version 2.02.05-1 from the lvm2 package makes my striped VG 
unreadable (the other vg does well), downgrading to 2.01.04-5 fixes the 
problem.

I can not give you the exact outcome of the vgdisplay but it gave about 
the same outcome as in the report of Igor Belyi, Tue, 28 Jun 2005 
19:11:49 -0400 (this appears to be the same problem), but some other name 
of the volume and other counter numbers (most probably 547 != 1094).

I would say it looked like (i can get you this but than I have to render 
my system 'unusable' first):
# vgdisplay datavolume
   LV backup: inconsistent LE count 547 != 1094
   Internal error: LV segments corrupted in backup.
   Volume group "datavolume" doesn't exist

now it says (with 2.01.04-5):
# vgdisplay datavolume
   --- Volume group ---
   VG Name               datavolume
   System ID             muziekje1075727894

   MAX LV                256
   Cur LV                1
   Open LV               1
   Max PV                256
   Cur PV                2
   Act PV                2
   VG Size               34.19 GB
   PE Size               32.00 MB
   Total PE              1094
   Alloc PE / Size       1094 / 34.19 GB
   Free  PE / Size       0 / 0
   VG UUID               elbhhh-3TS6-Qhju-ie78-13sj-rGG4-euaOEr

Attached is the /etc/lvm/backup/datavolume config file.
