I have an Ubuntu Server installation, and I only setup 20Gb on the 80Gb HDD using LVM at installation, thinking it would give me more options down the road. I should of just set up the whole partition, or at least a lot more.
I'm not too sure how to approach this issue, the volume is always mounted and the server is used quite a bit (but only for Dev, so it could be shut down for a few).
Here is the output of $ df -hT As you can see, I am running out of space...
maxxdev@maxxserver:~$ df -hT

/dev/mapper/maxxserver-root

and the output of $ lvdisplay
maxxdev@maxxserver:~$ sudo lvdisplay

If I use the lvextend -L +50G /dev/maxxserver/root (or however much space) will I be able to resize the volume while the system is running, plus I need (want) to avoid messing up the partition that is being used now (I guess that goes without saying :)
After resizing, do I still have to 'growfs' for the partition? If so can this happen on a 'live' system, or should I shutdown and do everything with a livecd or something?
