Greeting the Audience
Before we dive into the specific details, we want to greet our audience. This guide is for system administrators and IT professionals who are responsible for maintaining and managing servers. We understand that your work is critical and that you need reliable and efficient servers. Our guide aims to help you achieve that goal.
Whether you are new to Ubuntu or a seasoned professional, our guide has something for you. We believe that by the end of this article, you will have a deep understanding of server partitioning and the best practices to optimize your servers.
Ubuntu Server Partitioning Best Practices
Ubuntu Server partitioning best practices can be divided into different areas, including:
1. Root Partition
The root partition is the most crucial partition on your server. It contains the operating system files, libraries, and configuration files. We recommend allocating at least 15GB to the root partition. This space is enough to store the necessary files and updates for your server’s operating system. Additionally, we advise that you do not store any user data on the root partition. Doing so can cause the partition to fill up, leading to performance issues.
2. Swap Partition
The swap partition is a partition that functions as virtual memory. When your server’s RAM is full, the swap partition stores the data temporarily, allowing the server to continue functioning. We recommend allocating at least twice the amount of RAM to the swap partition. This allocation helps ensure that your server can handle the workload, even when the RAM is full.
3. /boot Partition
The /boot partition contains the files necessary for booting the server. It is recommended to allocate at least 512MB to the /boot partition. This partition is essential for the server’s boot process, and it must not be deleted or moved. Additionally, the /boot partition should not be encrypted.
4. /var Partition
The /var partition is a critical partition that contains log files, databases, and other system files. We recommend allocating at least 20% of the server’s total disk space to the /var partition. This allocation helps to ensure that the partition does not fill up quickly, leading to system performance issues.
5. /home Partition
The /home partition contains the user data and personal files. We recommend allocating the majority of the server’s disk space to the /home partition. Doing so allows users to store their data and files without taking up space on other partitions. Additionally, separating the /home partition from the root partition helps prevent issues with partition filling up.
6. Partition Encryption
Encrypting your server’s partitions can help prevent unauthorized access to your data. However, it can also lead to performance issues. We recommend encrypting only the partitions that contain sensitive data. Doing so can help improve server performance and reduce potential issues.
7. Partition Size
Determining the partition size can be challenging, especially when you consider the different factors that affect it. We recommend analyzing the server’s workload and the type of data to be stored before deciding on the partition size. Additionally, we advise that you allocate extra space to the partitions to prevent issues with partition filling up.

FAQs
1. Is it possible to resize partitions after installation?
Yes, it is possible to resize partitions after installation, but it is not recommended, as it can cause data loss and other issues. It is best to determine the partition sizes before installation and allocate the appropriate sizes.
2. Is it possible to encrypt all partitions on the server?
Yes, it is possible to encrypt all partitions on the server, but it can lead to performance issues. We recommend encrypting only the sensitive data partitions.
3. Can I store user data on the root partition?
No, it is not recommended to store user data on the root partition, as it can cause performance issues and lead to partition filling up. We recommend allocating the majority of the disk space to the /home partition for user data.
