If it is just a lvm problem, then you should first try running pvs, vgs,
and lvs. Those will tell you what LVM thinks that it has. Also you
should run 'fdisk -l /dev/sda' (or whatever disks you have) to see what
partitions your system thinks it has. Man lvm should give you some
general information on the lvm commands, but you will probably need to
read the individual man pages for more detail on the commands.

Hello Carl,

I've posted all of that in the past emails in this thread, however for the benefit of new people seeing this message (esp. those not using gmail with the conversation mode set on) here's the info again

lvm> pvs
PV VG Fmt Attr PSize PFree
/dev/sda2 DebSparcx64-01 lvm2 a- 43.21G 0
shows the main partition to be 43.21GB and if /dev/sda1 is boot and /dev/sda2 is the lvm volume and /dev/sda2 is the "whole disk", then how/where do I extend this volume to?

# lvs
LV     VG           Attr   LSize   Origin Snap% Move Log Copy% Convert
home   DebSparcx64-01 -wi-ao 30.47G
root   DebSparcx64-01 -wi-ao 264.00M
swap_1 DebSparcx64-01 -wi-ao   4.66G
tmp    DebSparcx64-01 -wi-ao 380.00M
usr    DebSparcx64-01 -wi-ao   4.66G
var    DebSparcx64-01 -wi-ao   2.79G

# fdisk -l /dev/sda
Disk /dev/sda (Sun disk label): 24 heads, 424 sectors, 8922 cylinders
Units = cylinders of 10176 * 512 bytes
   Device Flag    Start       End    Blocks   Id System
/dev/sda1             0        19     96672    1 Boot
/dev/sda2            19      8924 45308640   8e Linux LVM
/dev/sda3             0      8924 45405312    5 Whole disk

as per the above, /sda2 is extending from cylinder 19 to the last cylinder but it's coming u to only 43.21GB? Where did the rest of it go?
