How to divide linux into 2t partitions

Dividing method: 1. Use the parted command to partition, the syntax is "parted path to divide 2t partition"; 2. Use "mkfs.ext4 partition path" to format the newly divided partition; 3. Use "mount path" /mnt" to mount the partition to "/mnt".

Linux divides 2t partitions

When the disk partition is larger than 2TB under Linux, I cannot use the common fdisk command. At this time, we need to convert the large-capacity disk to GPT format first, and then Try the parted command to divide partitions larger than 2T.

Method:

1. Use the parted command to partition

[root@local /]# parted /dev/sdb　　　#划分大于2T的磁盘sdb
GNU Parted 1.8.1
Using /dev/sdb
Welcome to GNU Parted! Type 'help' to view a list of commands.
(parted) mklabel gpt　　　#把sdb磁盘转换为GPT格式
(parted) mkpart primary 0 100　　　#划分一个起始位置为0大小为100M的主分区
(parted) mkpart primary 100 200　　　#划分一个起始位置为100M大小为100M的主分区
(parted) mkpart primary 0 -1　　　#划分所有磁盘容量到一个主分区(此例把所有磁盘容量划分到一个分区)
(parted) print　　　#打印保存当前分区操作
(parted) quit　　　#退出

2. Format the newly divided partition

[root@local /]# mkfs.ext4 /dev/sdb1

3. Mount the sdb1 partition to /mnt

[root@local /]# mount /dev/sdb1 /mnt

4. Use the df command to view the mounted partition

[root@local /]# df -h
Filesystem 　　　Size 　Used 　Avail 　Use% 　Mounted on
/dev/sda2　　　　173G 　2.3G 　 162G 　 2% 　　/
tmpfs　　　　　　　16G 　 　0 　 　16G 　 0%　 　/dev/shm
/dev/sda1　　　　1.9G 　 61M 　 1.8G 　 4% 　　/boot
/dev/sdb1　　　　5.2T 　 60M 　 5.0T 　 1% 　　/mnt　　　#可以看到sdb1分区大小为5.2T，已挂载到/mnt目录下

parted is different from fdisk (
