This article is about how to partition disks larger than 2T. Xiaobian thinks it is quite practical, so share it with everyone for reference. Let's follow Xiaobian and have a look.

Since the disk enclosure was purchased specifically for storage, and later considering the dynamic management of disk capacity, LVM was prepared for dynamic expansion management. First, let the front-end mount machine recognize the logical volume group of the disk enclosure, for example: /dev/sdb

First, introduce two partition tables:

MBR partition table: Maximum supported volume: 2T (T; terabytes,1TB=1024GB) Maximum partition limits: 4 primary partitions or 3 primary partitions plus one extended partition. GPT partition table: (GPT meaning: GUID partition table) Maximum supported volumes: 18EB,(E: exabytes,1EB=1024TB) Maximum supported partitions per disk: 128

Use parted to create partitions larger than 2T:

1, parted /dev/sdb You can type p to print disk information, view partitions, and find where they start and end.

2, mklabel gpt Set partition type to gpt

3, mkpart primary 0 1572860primary refers to the partition type as the primary partition, 0 is the partition start position, and 1572860 is the partition end position.

4, quit after the completion of the quit command.
