hi,

after using for some time lvm without any problems, my lvm system
generates after rebooting some strang errors.

the problems look like these: 
http://www.copilotconsulting.com/mail-archives/linux-lvm.2005/msg00025.html

but the solution doesnt work for me.

summery:

system suse 10.1, boot drive sata /dev/sda (no lvm)
lvm composed of 8 ide drives (/dev/hda to /dev/hdh)

worked for some time, but i think the auto-update of suse screwed the
lvm. 

pvscan, pvdisplay, lvsvan and vgscan all generate errors. i have no idea
where the "logic extend" is already mapped. i cant diagnose the error. 

i think the pv are still intact, but i dont knwo how to put em back
together.

here are some of the errors:

tokyoo:/tmp # pvscan
  /dev/sdb: open failed: Kein Medium gefunden (No Media found)
  /dev/sdc: open failed: Kein Medium gefunden
  /dev/sdd: open failed: Kein Medium gefunden
  /dev/sde: open failed: Kein Medium gefunden
  logical extent (630) already mapped.
  Couldn't fill logical volume maps.
  logical extent (630) already mapped.
  Couldn't fill logical volume maps.
  No matching physical volumes found
tokyoo:/tmp # pvdisplay
  logical extent (630) already mapped.
  Couldn't fill logical volume maps.
  logical extent (630) already mapped.
  Couldn't fill logical volume maps.

remark: with every commad that generates an error i get the "No Media
found" error block für the /dev/sdx devices. i removed them to save
space.

but strangely the single drives are recognised as proper PV:

tokyoo:/tmp # pvdisplay /dev/hda1
  --- Physical volume ---
  PV Name               /dev/hda1
  VG Name               system
  PV Size               111,78 GB / not usable 0
  Allocatable           yes
  PE Size (KByte)       16384
  Total PE              7154
  Free PE               7154
  Allocated PE          0
  PV UUID               afdGTQ-95Qv-f3oL-anWh-V2LO-PKIf-eXTbRb

[...]

some other things i tried:
