Well, I have tried to reproduce this problem without LVM ----> fresh system installed ---> system updated------> no problem. Then again with LVM installation but with different partitions layout. All volume groups were on one physical volume as follows: linux-d6tk:/home/test # pvscan PV /dev/sda2 VG system lvm2 [7.69 GiB / 8.00 MiB free] PV /dev/sda3 VG system lvm2 [10.84 GiB / 0 free] PV /dev/sda4 VG system lvm2 [1.32 GiB / 0 free] Total: 3 [19.84 GiB] / in use: 3 [19.84 GiB] / in no VG: 0 [0 ] linux-d6tk:/home/test # linux-d6tk:/home/test # vgscan Reading all physical volumes. This may take a while...

It is really interesting why on above pv, vg, lvl layout - root_pv dissapear from the system and then system is unable to boot......
