exFAT stands for Extensible File Allocation Table and is a format made by Microsoft for use on devices like USB flash drives. In general, you do not hear a lot about exFAT these days, but it remains a viable format that is compatible with Windows, MacOS, and Linux, so it is a good choice for a flash drive that you plan on using with a variety of different systems. Some manufacturers even use exFAT as the default format for their SD cards or other products.

Check CPU and RAM usage of a Kubernetes pod
One of the most essential parts of Kubernetes administration is to keep an eye on resource usage for your master and worker nodes. Checking how much CPU and RAM resources a pod is utilizing can tell you if further scaling needs to be considered in order to deal with the increased load, or if a new configuration or hardware upgrade is in order. In this tutorial, we will look at different ways to check CPU and RAM usage of a Kubernetes pod on a Linux system.
Control CPU and RAM usage in Kubernetes
Kubernetes is typically used to scale containerized applications across many worker nodes. With more and more applications being deployed into your Kubernetes cluster, managing CPU and memory utilization becomes a crucial issue. In this tutorial, we will look at how to manage CPU and RAM usage in Kubernetes on a Linux system, in order to configure resource limits and ensure that containers are not using more than they are allotted.
Solving the ‘Segmentation Fault’ Error on Linux
The Segmentation Fault error (often called just segfault) is usually related to a memory issue whereby a process tries to access unallocated memory that does not belong to it, and the Linux kernel ends up terminating the process and issuing the error as a means to mitigate further issues. It can be tricky to diagnose and usually does not give us much to go off of, so we must dig through log files and try a variety of methods to figure out the root problem. In this tutorial, we will go through step by step instructions to solve the Segmentation Fault error on a Linux system.
Troubleshooting the ‘Disk Full’ Error on Linux Systems
When encountering the Disk Full error on a Linux system, it indicates that the partition being used to write or save data does not have enough space to perform the operation. There are various solutions to troubleshoot this error, which involve either creating more space on the partition or expanding the overall storage capacity. This tutorial will demonstrate how to resolve the Disk Full error and provide some fundamental Linux commands to help identify the issue.
How often do you have to reboot your Linux server?
Are you tired of constantly having to reboot your servers to fix issues or apply updates? You’re not alone. Server maintenance and uptime can be a tricky balance, and the decision of when to reboot a server comes with trade-offs. In this article, we’ll take a deep dive into the reasons why servers may need to be rebooted, the potential consequences of not rebooting, and the different approaches to server maintenance and uptime.
We’ll also explore tools and techniques that can minimize the need for reboots. Whether you’re a sysadmin, a developer, or a manager, this article will give you a better understanding of the complexities of server maintenance and uptime and help you make informed decisions about when to reboot your servers.
How to retrieve hardware information with dmidecode on Linux
Dmidecode is a free and open source utility we can use to retrieve hardware information on Linux. The tool is available in the repositories of all the major Linux distributions, and is able to inspect and dump the content of the SMBIOS table.
/boot/efi Linux partition: What is, usage recommendations
The /boot/efi partition is present on most Linux systems and is where the boot loaders (and sometimes kernel images and drivers) are stored for all of the installed operating systems on the disk. The system’s UEFI firmware will load these files upon system boot.
Clone partition on Linux
Making a clone of a disk partition is a great way to make a complete backup. This type of backup would preserve all your system and personal files on that particular partition. Cloning and restoring a disk partition is relatively easy, even if you are cloning the partition on to a completely different storage device.
How to format disk in Linux
Formatting a disk will get it ready for use as a storage device on your Linux system. The process involves partitioning the disk, adding a file system to the partition (this is the “formatting” part), and then mounting the partition to some path where you plan to access it from. This might sound complex or like a lot of steps, but it really only takes a few minutes.
MBR/DOS vs GPT partition scheme for Linux
When partitioning a hard disk or other storage device, you have a choice on what type of partition scheme to use. By far, the two most common partition schemes to use are MBR (Master Boot Record, sometimes also referred to as msdos) and GPT (GUID Partition Table). When preparing to partition and format your hard drive, it is important to understand the differences between these two schemes in order to choose which one is ideal for your situation.
How to check memory size in Linux
If you want to know the memory size of your Linux system, you will be relieved to know that it is not necessary to crack open the PC or boot into the BIOS screen to get your information. Linux allows us to check our memory size, and other relevant information such as spare slots and RAM speed, etc, all from within the operating system. We will go over some of these hardware checking methods below.
