I need more space.

So after I talked about my backup strategy, I went and started my command to sync my pictures. I went to checkup on it, and it was stuck. I checked, and I was out of space. Oh oh. I stopped the sync. Now what? Well, the drives are sporting LVM2, and I had extra space available, so I just added some.

First add some more space to the volume:
# lvextend -L +1G /dev/vgnas/pictures

Then tell ext3 about the extra space.
# resize2fs /dev/vgnas/pictures

Thats it. I did it live, without unmounting. I then went back to my rsync command, and it continued right where it left off. Sometimes I really like linux.
