This is about mine and my brothers ps4 his controller connected to mine and now won't connect back so my brother and I both have ps4's and I was playing with a friend when my controller died so I asked to use his and so I played with his main for a bit and he asked for me to switch to his second one so I did but now neither controller is connecting back to his ps I've tried the reset button, USB cords, going to settings and disconnecting and turning off the controller, and as of right now I even unplugged my play station but it's like it's stuck and only synced with mine and the light keeps flashing,,does anyone have any ideas on how I can fix this?

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.
