[linux-lvm] Volume group not accessible

I've lost the access to one of my Voloume groups which consists of
disk /dev/hdd1 (contains data) and device /dev/hdc1 (which contains no
vgscan -- reading all physical volumes (this may take a while...)
vgscan -- found active volume group "LVM"
vgscan -- ERROR "vg_read_with_pv_and_lv(): current PV" can't get data of
volume group "LVM2" from physical volume(s)
vgscan -- "/etc/lvmtab" and "/etc/lvmtab.d" successfully created
vgscan -- WARNING: This program does not do a VGDA backup of your volume
I think I've made the following mistake:
vdr:~# vgchange -an LVM2
vgchange -- volume group "LVM2" successfully deactivated
vdr:~# pvcreate -vff /dev/hdc1
pvcreate -- locking logical volume manager
pvcreate -- checking physical volume name "/dev/hdc1"
pvcreate -- getting physical volume size
pvcreate -- checking maximum physical volume size
pvcreate -- checking partition type
pvcreate -- checking volume group name
pvcreate -- really INITIALIZE physical volume "/dev/hdc1" of volume group
"LVM2" [y/n]? y
pvcreate -- WARNING: forcing physical volume creation on "/dev/hdc1" of
volume group "LVM2"
pvcreate -- removing lvmtab entry
pvcreate -- creating new physical volume
pvcreate -- setting up physical volume for /dev/hdc1 with 195318207 sectors
pvcreate -- writing physical volume data to disk "/dev/hdc1"
pvcreate -- physical volume "/dev/hdc1" successfully created
pvcreate -- unlocking logical volume manager
But it exists:
vdr:~# dir /dev/LVM2/Media
And now I'm not sure how to gain access again.
Should I try to restore metadata with vgcfgrestore?
Is it possible that I lost my data if I try vgcfgrestore?
Or should I create a new Volume group and include the device /dev/hdd1 to
this VG? If I do this, what the way to delete volume group LVM2?
Thanks in advance
