I was doing an update and it said that the drive was full.

Here is df -h:

/dev/sda1             228M  225M     0 100% /boot

Here is fdisk -l:

Here is mount:

/dev/sda1 on /boot type ext2 (rw)

Here is /etc/fstab:

# <file system> <mount point>   <type>  <options>       <dump>  <pass>

/dev/mapper/machine-root /               ext4    errors=remount-ro 0       1

# /boot was on /dev/sda1 during installation

UUID=08ddfaa4-0da2-405e-95b2-b228a95dc761 /boot           ext2    defaults     $

/dev/mapper/machine-swap_1 none            swap    sw              0       0

/dev/fd0        /media/floppy0  auto    rw,user,noauto,exec,utf8 0       0

How can I fix /dev/sda1 being mounted on /boot?

As I said in my comment, perhaps your only issue a full /boot partition. Since you're using LVM, the output you posted in fstab, mount, etc look fine.

And the best way to free space in /boot is to remove old kernel versions. If you're new to this, I suggest using Software Center:

Search for "linux-image". Take a note on the most recent one (your current kernel), and delete all the previous ones. Only remove the ones with version numbers like linux-image-3.2.0-xx-server, do not delete the "main" linux-image-server or linux-image. Be sure to keep your current version number.

Do the same with "linux-headers"

You're good to go!

Also, as a side-note... you may reconsider administering an Ubuntu Server if you still need tutorials for managing disk space and kernel versions. Have you tried Ubuntu Desktop?
