Thomas Waggoner, an information systems professor at the local university, is at the Will Call window at the Medallion Theatre, trying to pick up tickets he had reserved. However, due to an oversight which turns out to be rather frequent, his tickets were sold to another patron. Fortunately for Dr. Waggoner and his wife, who are celebrating their wedding anniversary, the box office manager finds two box seats which had not been claimed. In talking with the box office manager, Dr. Waggoner starts thinking that he could perhaps help the theatre avoid this type of problem in the future. His students could design and build a system to help keep track of ticket sales, and hopefully help the theatre become more efficient and improve customer satisfaction.

You have a linux system that has a 1000gb hard disk drive, which has a 90gb partition containing an ext4 filesystem mounted to the / directory and a 4gb swap partition. currently, this linux system is only used by a few users for storing small files; however, the department manager wants to upgrade this system and use it to run a database application that will be used by 100 users. the database application and the associated data will take up over 200gb of hard disk space. in addition, these 100 users will store their personal files on the hard disk of the system. each user must have a maximum of 5gb of storage space. the department manager has made it very clear that this system must not exhibit any downtime as a result of hard disk errors. how much hard disk space will you require, and what partitions would you need to ensure that the system will perform as needed? where would these partitions be mounted? what quotas would you implement? what commands would you need to run and what entries to /etc/fstab would you need to create? justify your answers.
