Linux-磁盘管理小结

这篇博文主要总结了Linux磁盘的一些操作，主要是硬盘的加载，分区（MBR分区和GPT分区），分区的挂载，以及swap分区的加载设置。

基础命令

df查看磁盘分区使用状况
1. -l //仅显示本地磁盘（默认）
2. -a //显示所有文件系统的磁盘使用情况，包含比如/proc/
3. -h //以1024进制计算最合适的单位显示磁盘容量
4. -H //以1000进制计算最合适的单位显示磁盘容量
5. -t //显示指定类型文件系统的磁盘分区
6. -T //显示磁盘分区类型
7. -x //不显示指定类型文件系统的磁盘分区
du统计磁盘上的文件大小
1. -b //以byte为单位统计文件
2. -k //以KB为单位统计文件
3. -m //以MB为单位统计文件
4. -h //以1024进制计算最合适的单位显示磁盘容量
5. -H //以1000进制计算最合适的单位显示磁盘容量
6. -s //统计指定目标
常用命令
1. df -lhT
2. df -lhT -t ext4(分区类型)
3. df -lhT -x ext4
4. du -s [指定目录]
5. du -sb *.zip //模糊匹配
6. du -sm *.zip
7. du -sh *.zip

回顾磁盘分区时的注意事项：

主分区和扩展分区总数不能超过4个。
扩展分区最多只能有一个
扩展分区不能直接存取数据

Linux系统中硬件设备都是以文件的形式存在于根目录下的Dev目录下。
硬件设备都是有Linux系统自动识别的。
添加的新硬盘，必须进行分区、格式化、挂载后才能使用。
MBR分区模式：主分区不超过4个，单个分区容量最大为2TB
GPT分区模式：主分区个数“几乎”没有限制，单个分区容量“几乎”没有限制。GPT分区中，最多可以支持128个主分区，且每个分区的大小突破了MBR分区的2TB的限制，最大为18EB=18432PB=18874368TB。缺点是GPT的主分区中，不适合安装X86架构的系统。

当硬盘空间消耗殆尽时怎么办？

比较好的做法应该是：在保留原硬盘的基础上，给服务器添加新的硬盘。

为虚拟机添加硬盘

将虚拟机关机（poweroff）。（当然，也有服务器的主板支持热插拔的。可以带电连接新硬盘。）
虚拟机设置->下面的“添加”->类型选择“硬盘”->下一步->选择硬盘类型（默认的(SCSI)就好）->创建一个新的虚拟机硬盘(下一步)->设置磁盘最大值；（没什么特殊要求，基本都是下一步,最后一步OK）。
重启Linux系统，使用fdisk -l//显示每个硬盘的分区列表（新添加的硬盘是没有分区表的）可以看到Disk /dev/sdb:和Disk /dev/sda:2块硬盘，以及sda的分区表，没有sdb的分区表。

先使用MBR分区模式为sdb分区。

[root@joe dev]#

fdisk /dev/sdb

    //进入分区模式
Device contains neither a valid DOS partition table, nor Sun, SGI or OSF disklabel
Building a new DOS disklabel with disk identifier 0x9ce83f46.
Changes will remain in memory only, until you decide to write them.
After that, of course, the previous content won't be recoverable.

Warning: invalid flag 0x0000 of partition table 4 will be corrected by w(rite)

WARNING: DOS-compatible mode is deprecated. It's strongly recommended to
         switch off the mode (command 'c') and change display units to
         sectors (command 'u').

分区完以后，就是格式化和挂载分区了。也就是设置文件系统。在这里需要注意以下内容：MBR分区只能格式化主分区和扩展分区，逻辑分无不能格式化 GPT分区，在格式化以后，只能使用parted 的print查看格式结果挂载分区：分区默认的挂载目录/mnt目录挂载点必须存在。

    //首先建立挂载点
[root@joe dev]#

mount /dev/sdb1 /mnt/joetest/

        //挂载分区
[root@joe dev]#

umount /mnt/joetest/

            //卸载挂载点

上面这中挂载方式是临时的，永久性的应该如下：
vim

+ /etc/

fstab
在末尾插入一行

swap交换分区（步骤为：建立一个普通的Linux分区，修改分区类型的16进制编码，格式化交换分区，启用交换分区。
