 Hi,

i have the following setup:

/dev/md2 --RAID1 (2x250GB)
/dev/md0 --RAID-5 (4x160GB)

both md-devices are added to LVM (2)
 
Library version:   1.02.03 (2006-02-08)
Driver version:    4.3.0

There are 1 VG and 10 LV's created. VG00 and LV00-LV09
Everything worked fine until i obviously did a mistake rezising the LV06.
(I resized othe LV's without problem before but with LV06 i forgot something
...)

Now i moved all other LV's to /dev/md0 with pvmove -n ..., exept for LV06
However i couldn't "lvremove" the LV06 (error: can't remove open lv or so)
I wasn't also able to deactivate the lv nor the vg.

So i tried to pvremove -ff the /dev/md2 PV (maybe the first big mistake)
Then i did a pvcreate on /dev/md2 again.

Now everything seems to be messed up:

The "unknown" device still contains the data of LV06. This data is not
important so i just want consistency back.

#lvremove vg00/lv06
  Couldn't find device with uuid 'faoJTZ-VDvh-Gqtd-V0jJ-qbMD-w8be-RvV4Dq'.
  Couldn't find all physical volumes for volume group vg00.

  Couldn't find all physical volumes for volume group vg00.
  Volume group "vg00" not found

Also, my cryptsetup gives errors:
 #/etc/init.d/cryptdisks start

Command failed: Es ist ein Block-Device notwendig (a block device is
necessary)

 swap0(running) swap1(running).

Any ideas what i can do now ?

Thanks in advance,
