LVM2 Volume and Volume group naming nomenclature

Ok, I am not try to start a flame war here, but I run dab smack into a walk that shouldn't be there. I have managed HPUX for many years which is the inspiration for Linux's LVM, and yes I know H.P. did not invent LVM. And for the most part you guys have done a pretty good job. I know it is a lot of hard work that has gone into this software.

But there is a major problem. LVM2 will not (from what I can see) recognize volume group names like VG00. I do not understand? Why type Volgroup00 when VG00 is quicker. In the HPUX version you can name the volume group and logical volume anything you want. I don't see why we can't do the same. It took me over a year to figure why LVM2 was not working in an install until I gave up naming the volume group and let it default to Volgroup00.

I commend all the programmers for this project, but respectfully ask that you change/modify and or add the logical and volume naming feature to this great product.

P.S.
If this is already in development then please disregard this message.

I think you must be confused, or you're not talking about what I think you are:

# vgdisplay

--- Volume group ---
VG Name vg0
[...]

Heck, you can call them whatever you want. I use "sys" and "data" on some of my machines. You can even rename them with vgrename.

And from a machine I just kickstarted today:

/dev/vg00/root
/dev/vg00/opt
/dev/vg00/usr
/dev/vg00/var
/dev/vg00/swap

You can probably guess where those have been mounted :) The only thing that's not under LVM control is /boot.

Ditto here....

machines 1 & 2:

# vgdisplay
  --- Volume group ---
  VG Name               raidvg
...

machine 3:

# vgdisplay 
--- Volume group ---
VG Name               Volume00

No idea what the O.P. is talking about.

Not sure what problems you were having with creating your volume group but I freed up some disk space and created VG00 just to be sure:

le:~# vgcreate VG00 /dev/hda4
  Volume group "VG00" successfully created
le:~# vgdisplay VG00
  --- Volume group ---
  VG Name               VG00
  System ID
  Format                lvm2
  Metadata Areas        1
  Metadata Sequence No  1
  VG Access             read/write
  VG Status             resizable
  MAX LV                0
  Cur LV                0
  Open LV               0
  Max PV                0
  Cur PV                1
  Act PV                1
  VG Size               9.44 GB
  PE Size               4.00 MB
  Total PE              2417
  Alloc PE / Size       0 / 0
  Free  PE / Size       2417 / 9.44 GB
  VG UUID
