Every filesystem is subject to fragmentation. On linux (using ext2/3 , 
xfs , jfs) , the filesystem is smart enough to keep fragmentation to a 
minimum level. Unlike windows/dos , you dont need to worry about this. 
If you reboot your system very often , it will sometimes check the 
integrity of the disk and that's all you'll see about disk maintenance 
in normal linux usage (you can run fsck to check your disks , but be 
sure not to run it on mounted filesystems. this is done automatically at 
boot time after a certain time period or a certain number of mounts).
