In a terminal type
man fsck
This will give the options for checking and repairing your disks. Since this is for a server, you will need to schedule the checks for the times the server is taken down - you can set your own schedule and run it via crontab so it can be unattended. Obviously you will need to check the logs after each scheduled reboot to make sure that there were no problems.

This thread might help on the defragmentation issue.

Frankly, I have never defragmented an ext3 or ext4 file system. Native Linux files systems are smarter than Windows file systems.

You don't need to defrag Linux filing systems. Most distros will check the filing system for you. Try the following:
su -c "tune2fs -l /dev/sda2"
This will give you useful info about the second partition, including things like

Mount count: 98
Maximum mount count: 100
Last checked: Mon Feb 7 16:10:53 2011
Check interval: 0 (<none>)

In other words, my system checks that partition every 100 boots, there are 2 to go before the next check, and the last was a month ago. For server that runs continuously, you'd set the check interval instead, like

su -c "tune2fs -i 1m /dev/sda2"

for a monthly check.
