1、查看已挂载好的磁盘，命令：df -h

> df -h
Filesystem      Size  Used Avail Use% Mounted on
devtmpfs        7.9G     0  7.9G   0% /dev
tmpfs           7.9G     0  7.9G   0% /dev/shm
tmpfs           7.9G  416K  7.9G   1% /run
tmpfs           7.9G     0  7.9G   0% /sys/fs/cgroup
/dev/xvda1       50G  1.6G   49G   4% /
tmpfs           1.6G     0  1.6G   0% /run/user/1000

2、列出可用磁盘，命令：lsblk -l

> lsblk -l
NAME  MAJ:MIN RM  SIZE RO TYPE MOUNTPOINT
xvda  202:0    0   50G  0 disk 
xvda1 202:1    0   50G  0 part /
xvdb  202:16   0  500G  0 disk 

3、找到为挂载的磁盘xvdb并格式化磁盘，命令：sudo mkfs.xfs -f /dev/xvdb

> sudo mkfs.xfs -f /dev/xvdb
meta-data=/dev/xvdb              isize=512    agcount=4, agsize=32768000 blks
         =                       sectsz=512   attr=2, projid32bit=1
         =                       crc=1        finobt=1, sparse=0
data     =                       bsize=4096   blocks=131072000, imaxpct=25
         =                       sunit=0      swidth=0 blks
naming   =version 2              bsize=4096   ascii-ci=0 ftype=1
log      =internal log           bsize=4096   blocks=64000, version=2
         =                       sectsz=512   sunit=0 blks, lazy-count=1
realtime =none                   extsz=4096   blocks=0, rtextents=0

4、将磁盘挂载到指定目录位置，命令：sudo mount -t xfs /dev/xvdb /home/zxb

> sudo mount -t xfs /dev/xvdb /home/zxb

5、查看挂载是否成功，命令：df -h

> df -h
Filesystem      Size  Used Avail Use% Mounted on
devtmpfs        7.9G     0  7.9G   0% /dev
tmpfs           7.9G     0  7.9G   0% /dev/shm
tmpfs           7.9G  416K  7.9G   1% /run
tmpfs           7.9G     0  7.9G   0% /sys/fs/cgroup
/dev/xvda1       50G  1.6G   49G   4% /
tmpfs           1.6G     0  1.6G   0% /run/user/1000
/dev/xvdb       500G  543M  500G   1% /home/zxb
