uhm... no. But I created a logical volume on a new VG
(I thought it's just a naming problem and tried to create VG
and LV with the same names. Mounting the file system failed and
I stopped any 'experimental' actions). So the filesystem should
be ok, but the metadata on the PV is somehow damaged.

I guess that the job is to force the assignemt of /dev/hdd1 to
VG "hxvg01" and to make this VG 'known' to the LVM and activate
the PVs.
I'm a bit lost know, because I don't know how to 'write back'
these information from the hxvg01.conf file to the PVs.

Any help would be deeply appreciated.
