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.
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.
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.
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.
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.
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.
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.
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.
Every hard disk, in order to be accessible under Linux, must have at least one partition on it. A partition is a way to logically separate different sections of a disk. For example, a 4 TB hard drive could have four different 1 TB partitions, and all would appear as separate storage systems under the operating system. Alternatively, a hard disk could simply contain a single partition that spans the entire volume. The configuration is entirely up to the user.
Ubuntu Linux is one of the most well known Linux distributions available. You have probably seen Canonical’s ubiquitous logo and the familiar look of Ubuntu Desktop running GNOME. What you may not have realized is that Ubuntu also has a very popular server edition of their operating system.
When you are adding a new disk to an existing Linux system, you will need to format and partition it, add a file system to it, and then mount the disk 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. The following tutorial will make it very easy.
If you want to perform a benchmark test on a USB thumb drive or other external USB hard drive, the procedure is quite similar to doing a benchmark test on an ordinary, internal storage device. All that we need to do is measure the read and write speed of the USB drive. In this tutorial, you will see how to benchmark test a USB drive via command line and GUI on a Linux system.
