@Guillermo
Well, I booted my server whit Knoppix and I solved learning better how to use LVM...
You know, this was my first time doing this kind of work on a LVM disk group.
Learning by doing is my preferred way!

@Johnny
fuser -m /var didn't tell anything, I tried to use it before ask this hel to you...

@ Robert

Next time I'll remember...

Hi all..
On my little test server I have 40GB hard disk.
I use LVM2, with 4 partitons: /boot, /home, /usr, /var
I set Apache to work in /var/www.
Now I added a 30GB hard disk to extend /var.
I regularly extended my volume group and the logical volume where /var stay.
Now I need to umount /var to run a resize2fs to extend the /var 
partiton, but I see ever the same message: "device is busy"
I tried to switch to runlevel 1, but no luck.
My var uses quota, and the fs is ext3.
    

  
Someone can help me?
Thank you a lot guys!
    

# lsof | grep '/var/'
