That did the trick thanks. :-)

Of course in a moment of not concentrating I messed things up again.  I still had pvremove on the disk from when I previously installed the lvm2 tools, and although I wanted to do a vgreduce I did a pvremove.  Even when it kicked up an error I just followed what it said and typed pvremove -ff. oops :-/

Now I get a a similar error as before with vgscan, and other tools give a 'VGDA in kernel and lvmtab are NTO consistent: please run vgscan' error.

I tried re-running what you suggested above but vgcfgrestore gives a 'can't restore part of active volume group "vg2"' error.

Is there anyway to recover from my stupidity (other than a lobotomy!)?
