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

vgscan -- "/etc/lvmtab" and "/etc/lvmtab.d" successfully created

groups

vdr:~# vgchange -ay
vgchange -- volume group "LVM" already active
