Partition with GPT when Linux hard disk exceeds 2 TB

As we all know, I cannot use common Fdisk commands when the disk partition in linux is larger than 2 TB. Is there no way to use large-capacity disks in linux? Answer: No. In linux, we can convert a large-capacity disk to the GPT format. As the GPT format disk is equivalent to the four partitions in the original MBR disk, we all know that in linux, when the disk partition is larger than 2 TB, I cannot use common Fdisk commands. Is there no way to use large-capacity disks in linux? Answer: No.

In linux, we can convert a large-capacity disk to the GPT format. Because the GPT format disk is equivalent to the 4*16 bytes of the four partition tables originally reserved in the MBR disk, only the first 16 bytes are reserved. Others are similar to extended partitions, the real partitiontable is after 512 bytes, so there is no limit on four primary partitions for the GPT disk table.

To operate the GPT disk partition table, we need to use the powerful parted command.

Example: common parted commands
# Parted/dev/sdb
GNU Parted 1.8.1
Using/dev/sdb
Welcome to GNU Parted! Type \ 'help \ 'toview a list of commands.
(Parted) mklabel gpt
Format the MBR disk as GPT
(Parted) mkpart primary 0 0 100
Divide a primary partition with a starting position of 0 and a size of MB
(Parted) mkpart primary 100 200
Divide a primary partition with a starting position of m and a size of M
(Parted) mkpart primary 0-1
Divide all spaces into one partition
(Parted) print
Print current partition
(Parted) quit
Some other commands that may be used
(Parted) mklable msdos
If you want to convert the GPT disk into an MBR disk
After partitioning, you must use mkfs. ext3 for formatting.
# Partprobe
# Mkfs. ext3-F/dev/sdb1

In practice:
Take redhat 5 as an example:
Parted/dev/sdb mklabel gpt. Convert to GPT. Parted/dev/sdb mkpart primary0 1000000 create 1 TB partition. Mkfs-t ext3/dev/sdb1mount/dev/sdb1/mnt/B. in this way, partition B of a large disk is mounted under the mnt Directory of the linux system.

Manually Mount upon startup
Vi/etc/fstab
/Dev/sdb1/mnt/B auto defaults 0 0
