4. 格式化分区

[root@zhaojie ~]# mkfs.xfs /dev/sdb1
meta-data=/dev/sdb1              isize=512    agcount=4, agsize=655360 blks
         =                       sectsz=512   attr=2, projid32bit=1
         =                       crc=1        finobt=0, sparse=0
data     =                       bsize=4096   blocks=2621440, imaxpct=25
         =                       sunit=0      swidth=0 blks
naming   =version 2              bsize=4096   ascii-ci=0 ftype=1
log      =internal log           bsize=4096   blocks=2560, version=2
         =                       sectsz=512   sunit=0 blks, lazy-count=1
realtime =none                   extsz=4096   blocks=0, rtextents=0

mkfs.ext4 /dev/sdb2
mkfs.ext4 /dev/sdb3
mkfs.ext4 /dev/sdb5
mkfs.ext4 /dev/sdb6

5. 创建挂载点

cd /opt/
mkdir sdb1 sdb2 sdb3 sdb5 sdb6

6. 挂载磁盘

[root@zhaojie opt]# mount /dev/sdb1 /opt/sdb1
[root@zhaojie opt]# mount /dev/sdb2 /opt/sdb2
[root@zhaojie opt]# mount /dev/sdb3 /opt/sdb3
[root@zhaojie opt]# mount /dev/sdb5 /opt/sdb5
[root@zhaojie opt]# mount /dev/sdb6 /opt/sdb6
[root@zhaojie opt]# df -hT

7. 配置自动挂载

vi /etc/fstab

/dev/sdb1               /opt/sdb1               xfs     defaults        0 0
/dev/sdb2               /opt/sdb2               ext4    defaults        0 0
/dev/sdb3               /opt/sdb3               ext4    defaults        0 0
/dev/sdb5               /opt/sdb5               ext4    defaults        0 0
/dev/sdb6               /opt/sdb6               ext4    defaults        0 0
