CentOS 7 挂载硬盘

--

1. 查看磁盘情况：fdisk -l​

[root@localhost /]# fdisk -l

Disk /dev/vda: 42.9 GB, 42949672960 bytes, 83886080 sectors
Units = sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disk label type: dos
Disk identifier: 0x000b714e

   Device Boot      Start         End      Blocks   Id  System
/dev/vda1   *        2048    83886079    41942016   83  Linux

Disk /dev/vdb: 64.4 GB, 64424509440 bytes, 125829120 sectors
Units = sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes

2. 格式化​

命令是：

 mke2fs -t ext4 /dev/vdb

或者

 mke2fs -t ext3 /dev/vdb

过程

[root@localhost /]# mke2fs -t ext3 /dev/vdb

3. 挂载到 /data 文件夹上​

mount /dev/vdb /data

4. 查看 df -h​

[root@localhost /]# df -h

devtmpfs        909M     0  909M   0% /dev
tmpfs           920M     0  920M   0% /dev/shm
tmpfs           920M   52M  868M   6% /run
tmpfs           920M     0  920M   0% /sys/fs/cgroup
/dev/vda1        40G  3.0G   37G   8% /
tmpfs           184M     0  184M   0% /run/user/0
