Need vgdisplay -v output for multiple volume groups

[Nikhil_1]

Hi,

Sorry for the silly request. But can someone please mail me output
of vgdisplay -v for more than 1 volume groups?
(I am writing parsing code for this and it is almost complete,
but need to know the separators for more volume group info).
My hotmail address is nikhilim@hotmail.com

With regards,
Nikhil

Hi,

How about vgdisplay -v /dev/vg* ?

Actually, I do not have access to a system where more than one volume group is present.
So I wanted to look at some sample output that contains info about more than one volume group (so that I can know where to stop parsing for one vg and start parsing for next vg).

With regards,
Nikhil

Hi Nikhil,

I've written a vgdisplay parser myself in Perl, but I think yours will be better.
Thus I had a similar need when I wanted to write it at home where I don't have access to an HP-UX box.
Luckily there was the wonderful work of Heinz Mauelshagen
(see
http://www.osdl.org/osdlpress/2001_aug_29_san_francisco.html
)
who wrote an LVM for Linux that has (almost) exactly the same interface as the HP-UX LVM (i.e. commands), and whose (pv|vg|lv)display produces (almost) exactly the same output.

You can set up a Linux box on any old PC and create LVs to your heart's content.
If you use a current Linux kernel (viz 2.4.X) it is already in the kernel sources
(run "make maenuconfig" and select LVM support).
Older kernels require more cumbersome semi-manual patching.
Then you only need to install the LVM tools from separat rpm file or source tarball.

You can find out more herin:

Btw, someone has already come up with an HPUX::LVM Perl module and published it at CPAN:
