提醒：挂载操作会清空数据，请确认挂载盘无数据或者未使用
第一步：查看所有分区表：命令 fdisk -l
[root@iZ8vb3dk693jocithqbofwZ ~]# 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: 0x0008d73a Device Boot Start End Blocks Id System /dev/vda1 * 2048 83884031 41940992 83 Linux Disk /dev/vdb: 493.9 GB, 493921239040 bytes, 964689920 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
这里可以看到 这个系统有两个磁盘 分别有 42g和493g 我们现在 vda是系统盘 我们现在来挂载 vdb
Disk /dev/vda: 42.9 GB, 42949672960 bytes, 83886080 sectors Disk /dev/vdb: 493.9 GB, 493921239040 bytes, 964689920 sectors
第二步：格式化硬盘 命令：fdisk /dev/vdb1
第三步：创建分区 命令：mkfs.ext4 /dev/vdb1
[root@iZ8vb3dk693jocithqbofwZ ~]# mkfs.ext4 /dev/vdb1
mke2fs 1.42.9 (28-Dec-2013)
Filesystem label=
OS type: Linux
Block size=4096 (log=2)
Fragment size=4096 (log=2)
Stride=0 blocks, Stripe width=0 blocks
30146560 inodes, 120585984 blocks
6029299 blocks (5.00%) reserved for the super user
First data block=0
Maximum filesystem blocks=2269118464
3680 block groups
32768 blocks per group, 32768 fragments per group
8192 inodes per group
Superblock backups stored on blocks:
32768, 98304, 163840, 229376, 294912, 819200, 884736, 1605632, 2654208,

102400000
Allocating group tables: done
Writing inode tables: done
Creating journal (32768 blocks): done
Writing superblocks and filesystem accounting information: done
第四步：挂载分区 命令：
mount /dev/vdb1 /data0 # 将vdb这个硬盘挂载成为 /data0
[root@iZ8vb3dk693jocithqbofwZ ~]# mount /dev/vdb1 /data0
如果成功你可以在 /etc/fstab 文件里面看到
UUID=eb448abb-3012-4d8d-bcde-xxxxxxxxx / ext4 defaults 1 1
或者使用lsblk -f 来查看挂载
[root@iz8vb3dk693jocithqbofwz local]# lsblk -f NAME FSTYPE LABEL UUID MOUNTPOINT vda └─vda1 ext4 eb448abb-3012-4d8d-bcde-xxxx / vdb ext3 cb4e4e59-953d-4f87-93ef-xxxxx └─vdb1 ext4 52d8cfbe-44d0-4906-a67e-xxxx /data0
第五步：将信息写入fstab,让系统开启自动挂载。在fstab文件添加如下代码
/dev/vdb1 /data0 ext4 defaults 0 0
