1.LVM Principles To understand the principles of LVM, we must first grasp four basic concepts of logical volumes. ① PE (Physical Extend) – Physical Extend ② PV (Physical Volume) – Physical Volume ③ VG (Volume Group) – Volume Group ④ LV (Logical Volume) – Logical Volume PV (Physical Volume) A physical volume is the basic … Read more
The Rust compiler is renowned for its ability to optimize code performance and manage memory, thanks to its borrow checkers. Rust code is compiled using the official compiler <span>rustc</span>, which utilizes LLVM as its backend to optimize and convert high-level Rust code into low-level machine code. However, a recent alternative has emerged called gccrs, which … Read more
Problem Analysis Due to selecting standard partitioning instead of LVM (Logical Volume Management) when installing the system in VMware, the vgextend command cannot be used to dynamically extend the root partition (/). The created partition disk is sdax. At this point, entering the system and typing vgdisplay will yield no response, as there is currently … Read more

padluo Reading time required: 4 minutes Quick read only takes 2 minutes Related Concepts Let’s first look at several concepts of LVM (Logical Volume Manager): In LVM (Logical Volume Manager), the relationships between various components can be summarized as follows: Physical Volume (PV): This is an actual disk partition or an entire disk that, after … Read more
Common Operations of Linux LVM LVM (Logical Volume Manager) is a logical volume manager in Linux used for managing disk storage. It abstracts physical hard disk partitions into Physical Volumes (PV), combines them into Volume Groups (VG), and then divides them into Logical Volumes (LV). LVM supports dynamic resizing of volumes, snapshots, striping, and other … Read more
