In a previous tutorial we discussed about the /etc/fstab file, and how it is used to declare the filesystems which should be mounted on boot. In the pre-Systemd era, filesystem where mounted in the order specified in the /etc/fstab file; on modern Linux distributions, instead, for a faster boot, filesystem are mounted in parallel. Systemd manages the mounting of filesystems via specifically designed units automatically generated from /etc/fstab entries. For these reasons a different strategy must be adopted to establish the dependency between two filesystems, and therefore to set their correct mount order.
Checking the file system for errors is an important part of Linux system administration. It is a good troubleshooting step to perform when encountering bad performance on read and write times, or file system errors. In this tutorial, we will explain a procedure on how to force fsck to perform a file system check on the next system reboot or force file system check for any desired number of system reboots, whether it is the root or a non-root mount point.
NTFS stands for New Technology File System and is developed by Microsoft for use on their Windows operating systems. NTFS is normally used on Linux systems, but has been the default file system on Windows for many years. Linux users are probably used to seeing drives with the ext4 file system, which is ordinarily the default and certainly the most widespread in the Linux realm.
If you want to run Ubuntu Linux on your system but you already have Windows 10 installed and don’t want to give it up completely, you have a couple of options. One option is to run Ubuntu inside of a virtual machine on Windows 10, and the other option is to create a dual boot system. Both options have their pros and cons.
Most of the non-SSD hard drives allow for a noise reduction by decreasing head movement speed while accessing data. This ability is called Automatic Acoustic Management or AAM. In this tutorial, you will see how to install the
hdparm software package on all major Linux distros and use it to manipulate AAM values to reduce or increase head movement, thus directly affect hard drive’s noise level.
inxi Linux command can be used to see various system information and other handy bits of data right from your terminal. The command is ordinarily not installed by default. However, it is a small software package that provides access to the command, and it proves especially useful to system administrators and power users.
If you are having trouble booting into your Ubuntu 22.04 system, there is a tool called Boot Repair that can remedy a broad range of frequent issues. Usually trouble with booting can be due to the GRUB boot menu or a corrupt file in the
/boot directory. Whatever the case may be, Boot Repair is an excellent software to help us start troubleshooting.
The best way to keep your Ubuntu 22.04 system and files completely secure in the case of theft is to enable full disk encryption. This way, if your device is stolen or someone is sitting at your desk and trying to boot into your PC, they will need to know your password in order to mount any partitions. Even if they access the hard drive content through other means, all files would be encrypted and no one could read their contents.
The partition table of a hard disk holds all the information about where each partition begins and ends. If the partition table gets deleted or becomes corrupt in some way, most likely your operating system will not be able to boot or you will face other hard disk issues. But there is good news: if your partition table is lost, it is possible to recover it using software such as testdisk.
