问题

加购了一个4TB的ssd用于装载数据，使用fdisk挂载时候遇到一下warning：

$ sudo fdisk /dev/sdbWelcome to fdisk (util-linux 2.34).
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.
The size of this disk is 3.7 TiB (4096805658624 bytes). DOS partition table format cannot be used on drives for volumes larger than 2199023255040 bytes for 512-byte sectors. Use GUID partition table format (GPT).

解决办法

$ sudo parted /dev/sdb
GNU Parted 3.3

这时候再使用fdisk就可以看刚才的分区了

Disk /dev/sdb: 3.74 TiB, 4096805658624 bytes, 8001573552 sectors

然后正常挂载硬盘
格式化：

$ sudo mkfs /dev/sdb

挂载：

$ mkdir /data
$ mount /dev/sdb /data

检查：

$ df -h

完工！
