Hi,
I'm currently running an ubuntu server 10.04 LTS headless and connecting via a combination of putty, webmin and occasionally VNC. When I initially setup the box I used LVM and gave the root partition 4Gb and the swap 8Gb, however I now have used 3.5Gb on the root filesystem and would like to extend it. Having read a number of threads and explanations I wonder whether someone could verify what the simplest and ideally safest way to achieve this is. FYI here is my fdisk -l, df and lvs outputs:
root@server:~# lvs
LV VG Attr LSize Origin Snap% Move Log Copy% Convert

media server -wi-ao 1.37t
music server -wi-ao 300.00g
osbackup server -wi-ao 10.00g
temporary server -wi-ao 200.00g
xhomes server -wi-ao 50.00g

In the list of LVS I cant see the root partition and the webmin config module doesn't appear to see it either.
Would the best option be to plug in a live cd and attach a monitor and keyboard?
Many thanks for any help received x
