Hello All!
I had a disk crash on my system and now I need to have my VG back, but
how? I had two HDDs, one containing root partition and one with LVM. HDD
with root partition crashed and backup was too old to restore :-( Now I
installed new system (RedHat 8.0) and need urgently to have my files from
old LVs, but I can't. Please help me! Look down, I think that problem is
in PV#, but how can I change it?
Output follows:
