Volume Group creation (SOLVE)

[Stephen Liu]

Hi Alexander and folks,

Finally I have VG and LVs created on GUI and got Ubuntu-6.06-amd64
installed.  I'm now posinting this email from Ubuntu box.  There was no
problem on the HD.

The trick was after having VG and LVs created, I have to activate them
allocating them as /, /home, etc.  Otherwise I was unable to finish
partitioning.  On saving it complained / not found.  It took me
sometime to dicovery this trick.

I prefer to run command lines creating VG and LVs rather than clicking
around on screen with the mouse.

What commands shall I run additional to;

# vgange -a y /dev/VG/UbunuRoot
# vgange -a y /dev/VG/UbuntuHome
etc.
to allocated them /, /home, swap, etc. respectively under VG.

Please shed me some light.  I'll have another round later.  TIA.

B.R.
SL
