パーティション作成

いつも通りパーティション作成をしようとすると次のようなメッセージが出てくる

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)

つまり

DOSパーティションテーブルフォーマットは、512バイトセクタで2TBを超えるボリュームのドライブでは使用できません。GUIDパーティションテーブルフォーマット(GPT)を使用してください。

ってこと。なのでコマンドでは g を押すのを忘れずに。

root@wasat:~# fdisk /dev/sda

Welcome to fdisk (util-linux 2.37.2).
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 14.6 TiB (16000900661248 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).

Created a new DOS disklabel with disk identifier 0x7f1fbc69.

Command (m for help): g
Created a new GPT disklabel (GUID: 4A9CF6C1-307D-294B-AA3C-5F5B71C7FAE3).

Command (m for help): w
The partition table has been altered.
Calling ioctl() to re-read partition table.
Syncing disks.

これでMBRではなくGPTパーティションテーブル形式になる。
