1.查看新挂载的卷名，可根据容量判断Disk /dev/sdb 512G

[azureuser@onezos /]$ sudo fdisk -l

2.分区

[azureuser@onezos /]$ sudo fdisk /dev/sdb

Welcome to fdisk (util-linux 2.32.1).
Changes will remain in memory only, until you decide to write them.
Be careful before using the write command.

Device does not contain a recognized partition table.
Created a new DOS disklabel with disk identifier 0x15fe7954.

Command (m for help): n
Partition type
   p   primary (0 primary, 0 extended, 4 free)
   e   extended (container for logical partitions)
Select (default p): p
Partition number (1-4, default 1): 
First sector (2048-1073741823, default 2048): 
Last sector, +sectors or +size{K,M,G,T,P} (2048-1073741823, default 1073741823): 

Created a new partition 1 of type 'Linux' and of size 512 GiB.

Command (m for help): p

3.格式化

[azureuser@onezos /]$ sudo mkfs.xfs /dev/sdb1

4.MOUNT新挂载的卷

[azureuser@onezos /]$ sudo mount /dev/sdb1 /data
[azureuser@onezos /]$ sudo chmod 755 /data
[azureuser@onezos /]$ cd /data
[azureuser@onezos data]$ mkdir zdtee
mkdir: cannot create directory ‘zdtee’: Permission denied
[azureuser@onezos data]$ sudo chmod -R 777 /data
[azureuser@onezos data]$ mkdir zdtee
