Hi all,
Not anyone out there having a clue on what to do? It seems that about
the same thing has happened to the submitter of
https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=142737 "Fedora Core
3 system with lvm2 won't boot". Is this acceptable? Because of its
impact., this is the kind of bug my company would consider a
"show-stopper", and relabel the project "beta" again.
So if there is no way to fix the error, is there any way to recover any
of my ~300GB of data? Fourtunately I have backuped all the crucial
stuff, but there are a lot of things I would want to recover.
Best regards,
Daniel
