Linux查看与挂载新磁盘

新创建的Linux系统，明明给的是120GB的磁盘空间。

 

在系统通过df -h查看磁盘空间却没有这么多，原因是磁盘未挂载到系统所致，

df -h 查看磁盘占用情况，却发现插入的一块硬盘/dev/sda 消失了 是磁盘坏了还是没被系统识别。

 

通过命令fdisk  -l 

 

 Disk /dev/sda: 128.8 GB, 128849018880 bytes

255 heads, 63 sectors/track, 15665 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes

可见/dev/sda  是存在的， 只需要mount就好，

2.新建一个文件夹，作为将来访问 sda的标识，

[root@localhost ~]# mkdir /data1

3. 查看磁盘sda1的文件系统类型

4.挂载磁盘sda1到data1

 

 

 5. 用df -h  可以查看到新挂载的磁盘sda1.

 

 

lsblk  查看当前磁盘情况
df -lh  查看文件系统情况 -l 查看挂载点
parted -l 会列出文件系统类型
fdisk -l 查看当前未挂载硬盘
