挂载硬盘
先分区,再格式化,然后挂载
查看硬盘状态
通过fdisk -l 可以看到/dev/vdb 200G 未进行分区格式化
[root@ecs-9c6d-a493 /]# fdisk -l

挂载分区
- 创建挂载目录: mkdir /project/data
- 挂载
[root@ecs-9c6d-a493 /]# sudo blkid /dev/vdb1 # # 获取分区 UUID
/dev/vdb1: UUID="f2c3332f-e517-48f7-9780-b2ec9ee73a6b" BLOCK_SIZE="512" TYPE="xfs" PARTLABEL="primary" PARTUUID="9b2cbf19-96d3-46ee-910a-530fe6a64620"
- 添加或修改配置
sudo vi /etc/fstab # 修改UUID的值
UUID=f2c3332f-e517-48f7-9780-b2ec9ee73a6b /project/data xfs defaults 0 0 # xfs
验证挂载结果
sudo mount -a
df -hT /project/data
df -h
结果如下
[root@ecs-9c6d-a493 data]# sudo mount -a
[root@ecs-9c6d-a493 data]#
[root@ecs-9c6d-a493 data]#
[root@ecs-9c6d-a493 data]# df -hT /project/data
