system can't boot and mount logical volumes of volume group after upgrade. I have /usr and /var partition as logical volumes, so my options are very limited. vgdisplay don't show me any logical volume vgscan found volume group vg0 in vg0 metadata is all configurations about logical volumes saved correctly. I have backup of metadata too vgscan read correctly metadata from physical volumes #label/label.c:158 /dev/sda12: lvm2 label detected #cache/lvmcache.c:665 lvmcache: /dev/sda12: VG vg0 no longer exported #format_text/format-text.c:954 /dev/sda12: Fiybd netadat at 6656 suze 6372 for vg0 (blah blah blah) #cache/lvmcache.c:665 lvmcache: /dev/sda12: VG vg0 now exported ... #metadata/pv_manip.c:241 /dev/sda8 0: 0 680: downloads(0:0) ... #metadata/pv_manip.c:241 /dev/sda6 2: 2201 183: NULL(0:0) ... $dmsetup ls No devices found $vgdisplay VG Name vg0 System ID Format lvm2 Metadata Areas 8 Metadata Swquence No 270 VG Access read/write VG Status exported/resizable MAX LV 255 Cur LV 6 Open LV 0 Max PV 255 Cur PV 8 Act PV 8 .... $lvdisplay ...
