AW: [linux-lvm] please help: unable to get rid of LV

[Cisco]

Hi again,

i now manged to restore the uuid on /dev/md2, and i'm now able again to
access all LV's.
But i can't get rid of LV06:

e2fsck -f /dev/mapper/clv06
e2fsck 1.39 (29-May-2006)
Die Dateisystem Größe ( laut SuperBlock) ist 14417920 Blocks
Die physikalische Größe von Gerät ist 7864320 Blocks
Entweder der SuperBlock oder die Partionstabelle ist beschädigt!
Abbrechen<j>? ja

translation: the superblock tells that the filesystem is 14417920 blocks
big, but the physical size is 7864320.
#lvremove /dev/vg00/lv06
  Can't remove open logical volume "lv06"
here i'm stuck again ...
