In practical projects, Linux system servers often encounter situations where disk space is insufficient, necessitating disk expansion. There are two scenarios for disk expansion: one is to mount a new disk block to the server and then perform logical partitioning on the newly mounted disk block; the other is to expand existing disk partitions, meaning … Read more
In today’s cloud and virtualization environments, dynamically adjusting server resources has become the norm. However, manually expanding disk partitions, especially on Linux systems using LVM (Logical Volume Manager), remains a cumbersome and risky task. A single erroneous command could lead to data loss. So, how can we achieve “plug-and-play” disk expansion, allowing the server to … 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
This tutorial has been tested on the OpenWrt soft router system compiled by the author, as well as on the OpenWrt soft router system compiled using Lean’s source code. Other non-Lean source code compiled OpenWrt soft router systems have not been tested, hence this note. 1. Open the disk management of the OpenWrt soft router … Read more

From the introduction of Bluetooth 1.0 in 1999 to the latest Bluetooth 5.3 standard, the evolution of Bluetooth technology has gone through a long process. Below is a … Read more
Because the space provided by the firmware is really too small, just installing a few software can cause problems, so it is strongly recommended to prioritize disk expansion after installation! Disk expansion involves different methods for different versions. The version we downloaded and used is ext4, while another version is squashfs. Ext4 Disk Expansion 1. … Read more
