Hello group, 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 data) vdr:~# vgscan 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 groups 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 /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?
