We are still looking for more people to run for e-board for next semester so far we have as nominations
* President - Eric Steve
* Server Team - Zach Jones

We will be doing elections next week so if you would want to run for a position com by next week's meeting Thursday at 5pm in Rekhi 101 feel free to bring a friend.

During our meeting I did a demonstration on how to manipulate partition size on a computer that uses an ext4 file system that does not use lvm. A copy of the procedure is attached for those that missed it. Next week we might go over something a bit more practical like setting up .bashrc file or your .nanorc file.

== How to resize a file system without needing to copy from backup. ==

=== Reasons why to resize a file system? ===

* Created a root file system that is too small for programs
* want to remove a swap partition for a swap file
* want to get rid of partitions that aren’t really needed for your use case ( such as if you had a separate partition for /var, /tmp, /boot, or /usr )

=== Before you begin ===
* If unsure read the man page
* Make a proper backup of critical data snapshots might not work because you are altering partitions and file systems
* If you need to shrink root you will need to be on a different boot device such as a install media
* Also this is for ext2/3/4 partitions without using lvm would potentially work for xfs with the exception that you should not shrink xfs

=== Shrinking a file system (where target_partition is the partition that is being made smaller) ===
umount partition if mounted, and shrink the file system to the minimum size, then check size we can use the df command for this and resize
<syntaxhighlight lang="bash">
e2fsck -f target_partition
resize2fs -M target_partition
mount target_partition
df -h
umount target_partiton
</syntaxhighlight>
use your favourite tool the change the partition size to what you, make sure it is bigger that the file system size
=== Shifting the partition to a later part of the drive ===
use the sfdisk command and enter shift amount for example shift the partition 4G
<syntaxhighlight lang="bash">
sfdisk –move-data target_drive -N partition_number
+4G
</syntaxhighlight>
or
<syntaxhighlight lang="bash">
echo “+size” | sfdisk –move-data target_drive -N partition_number
</syntaxhighlight>

=== Expanding a file system (does not need to be unmounted) ===

==== alter partition table for it to grow in size ====

if unmounted run:

<syntaxhighlight lang="bash">
e2fsck -f target_partition
resize2fs target_partition
</syntaxhighlight>
