RE: [PLUG] Recovering a LVM

["Bradley Molnar" <brmolnar@ursinus.edu>]

This is a linux LVM.  I believe that it shipped with redhat8.  Either way,
it was running on Redhat8 (will now be running on redhat9)

My guess was that it was hopeless, but, I thought I would see if anyone knew
anything before we reformatted the drives and started over (backing up this
time).

thanks

If it's anything like commercial (Veritas, Sun) volume managers and
the partitioning information isn't preserved somewhere other than on
the failed disk you can't recover it. And if no one bothered to
record the physical disk allocations offline, you're really screwed
because you can't just allocate the same sector counts and hope.

Note that I've never tried to use (either; I note you don't say
which of the, to my knowledge, two pieces of software running by
that name nor what version of it you're using) LVM, so that's all
just an educated guess.
