ubuntu使用Parted GPT 创建大于2TB的的分区

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/sdb

Welcome 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
Using /dev/sdb
Welcome to GNU Parted! Type 'help' to view a list of commands.

(parted) print

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
Disk model: GLOWAY STK4TS3-S
Units: sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disklabel type: gpt
Disk identifier: 9B8B4FC7-7B68-4835-A611-DE53D8887EB8

Device     Start        End    Sectors  Size Type
/dev/sdb1   2048 8001572863 8001570816  3.7T Linux filesystem

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！
