Either a tag "@tagname", a volume group as "vgname", or a logical
volume name as "vgname/lvname" (otherwise the tools cannot know which
LV you mean if there are multiple LVs with the same name in different
VGs).

In your earlier example you seemed to have an LV name:

>> Volume_list  =  [ "myrootvolume", "@hostname" ]

Which won't work since the LV name is unqualified by a VG. Your later
example:

> volume_list = [ "vg_pdcpicpl01", "@PDC-PIC-PL-01" ]

Looks correct assuming that vg_pdcpicpl01 is the name of a VG on your
system.

It's up to you whether you want to specify just an LV or a whole VG.

It's hard to say. What error do you get initialising LVM? Try adding
more -v if there's nothing useful printed (normally syntax errors in
lvm.conf give a useful message).

Failing that you could post your full lvm.conf to a pastebin somewhere
and mail the link so that others can review your config.

Bryn.
