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.

3.格式化

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
