fixed-size units of space. In particular, an extent is the smallest amount of space that can be allocated by LVM in Linux. All LVs in a VG are of the same size. LVM maintains a mapping between all logical and physical extents. This mapping is merely the LV, which can be expanded by...
GRUB Legacy (GRUB 1). This deprecated version of GRUB is still found on some olderLinux distributions. GRUB 2. This GRUB version supports new PC architectures (such asARM) andfilesystems(such asReiserFS),RAIDenvironments, and LVM. Most of the current distributions use GRUB 2. For example, ...
The Logical Volume Manager, or LVM, is a Linux-based program that provides storage virtualization for system administrators. Since it's far more flexible than disk partitioning, it's become a common alternative. Although it's primarily used in large-scale settings, like when balancing the needs...
lvm-001.png Logical Volume Management (LVM) is a disk management option that every major Linux distribution includes. Whether you need to set up storage pools or just need to dynamically create partitions, LVM is probably what you are looking for. What is LVM? Logical Volume Manager allows fo...
To setup LVM, we first need an overview of all drives connected to the machine. We can list them usinglsblk: sudo lsblk The output looks something like this: As you can see in the “type” column, we have one disk attached to the server a size of 400 GB and a few partitions. The...
Here learn about the shell which is an important part of the Linux operating system. The shell in the Linux operating system is used as a command line interpreter. It works between user input and Linux Kernel.
We are currently using LVM to manage our disk space. When using fdisk to create a partition, both types work with LVM, i.e. 83 (Linux) or 8e (Linux LVM). What are the advantages of using one over the other?Environment Red Hat Enterprise Linux 4 Red Hat Enterprise Linux 5 Red Hat...

在Unix/Linux系统中,需要执行fork系统调用后exec系统调用来启动一个新进程。fork调用会克隆当前执行的进程,而exec调用则会在调用进程上覆盖一个基于不同可执行文件的新进程。 2.7 What is the purpose of system programs? 答: 为程序开发和运行提供了方便的环境 ...
Subvolumes behave like a partition but are not the real disk partition. They can be compared to something like Volumes used in LVM (Logical Volume Manager). Subvolumes make resizing quick and flexible as compared to real partitions. Interestingly, a Btrfs snapshot is also a subvolume that sha...
