You have a Linux system that has a $2$ TB SSD$,$ which has a $90$ GB partition

containing an ext$4$ filesystem mounted to the $/$ directory and a $4$ GB 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 $600$

GB of hard disk drive space. In addition, these $100$ users will store their personal files on the

hard disk drive of the system. Each user must have a maximum of $5$ GB of storage space. The

department manager has made it very clear that this system must not exhibit any downtime

as a result of storage device errors.

a$)$ How much space will you require, and what partitions would you need to ensure that the

system will perform as needed?

b$)$ Where would these partitions be mounted?

c$)$ What quotas would you implement?

d$)$ What commands would you need to run and what entries to $/$etc$/$fstab would you need

to create?
