前言介绍

本 PXE 自动化部署平台，面向国产化统信 UOS 服务器打造，完整支持 x86_64、aarch64、loongarch64 三大硬件架构，兼容 BIOS 与 UEFI 两种启动模式。平台整合 DHCP、TFTP、HTTP 服务，通过 Kickstart 无人值守应答脚本实现操作系统全自动安装，无需人工干预。可自动完成磁盘分区、系统基础配置、账号密码策略、LVM 分区配置、网络参数预设、系统安全基线初始化等工作。统一管理统信 UOS Server 多版本镜像资源，一套服务同时支撑异构服务器批量上线，大幅减少重复装机操作，提升机房服务器部署效率，满足国产化环境规模化运维需求。

从磁盘硬件到Ext文件系统-Linux磁盘级文件系统学习笔记

本文系统梳理了从磁盘物理结构到Ext文件系统的底层原理：磁盘以磁性存储实现持久化，通过CHS与LBA实现寻址；操作系统以4KB块为单位管理磁盘，通过分区与块组组织空间；文件由独立的inode（属性）与data blocks（内容）构成，通过inode中的i_block[]关联；删除仅修改位图，数据残留可恢复；内核通过page与缓冲区高效管理块。全程揭示了“文件未打开时”的本质——是磁盘上由块、位图
