[linux-lvm] Unable to import exported VG



Hi,

I have a problem with importing an exported Volume Group. Hopefully you can help me with this.

Here's the error message:

matrix:/tmp # vgimport -v -f vgData /dev/hdb1
vgimport -- locking logical volume manager
vgimport -- checking volume group name
vgimport -- checking volume group "vgData" existence
vgimport -- trying to read physical volume
vgimport -- checking for duplicate physical volumes

vgimport -- reallocating memory
vgimport -- reading exported volume group data  of "vgData" from disk(s)
vgimport -- ERROR "lv_read_all_lv(): number of LV" reading data of volume group "vgData"


Background Information:

The power supply of my PC broke. After replacing it, the system would not boot, so I tried different
things to recover. One of these things was booting Knoppix. This worked only after I removed an
apparently broken USB card. I was stupid enough to try and mount the VG within Knoppix. It did
not work, but I issued the vgexport command for no real reason *sigh*
After that I bootet my normal system (see below) and was unable to mount or import the VG.


Some more info on the system:

I attached the output of vgscan -d as gzipped file.

Please let me know if you need any more information.
Thank you very much in advance for any help!
