Heinz,

When I type in pvdata /dev/sda5 I get the following output.

--- NEW Physical volume ---

I'm assuming that it cannot find the LVM partition information.
Unfortunately I do not have a backup copy of the /etc/lvmconf/* files.  If
you know of anything else I could try it would be greatly appreciated.

Thanks,
Darryl

Darryl,

as Patrick said, vgscan should find your LVM partition fine unless it got
written over.

In case just the LVM metadata at the beginning of that partition (~ < 1MB)
got overwritten during install, backups of /etc/lvmconf/* and
vgcfgrestore(8)
are your friends as Sander metioned. If more is gone you probably wont't get
back a whole lot of useful data.

Any progress so far?

Well, this looks like a whole lot of zeroes at the beginning of /dev/sda5 :(
Not really recoverable.

Nope, sorry.
At least you need LVM metadata archive backups (/etc/lvmconf/*) or backups
of your data.
Both would have been better though...

[linux-lvm] Can't find LVM partition

[Stauffer, Darryl]

Hello,

I just got done upgrading from Redhat 7.2 to Redhat 7.3.  My home directory
was setup on its own partition using LVM and reiserFS.  The upgrade was done
by formatting the original root partition and reinstalling OS which means
that all the LVM info is gone.  Is there any way to recover my LVM
partition?

Thanks,
Darryl

Hallo Darryl,

I've not used LVM for a long time, but if you have backups of the
meta data it should be possible using vgcfgrestore.

If all that was upgraded was an existing non-LVM root partition then vgscan
should fine the LVM bits again without help.
