Disk Mount method after 16TB

Overview:

A trusted server, a total of 24 900GB SAS hard drives, the array configuration is as follows:

1 , using the first 23 hard drives for RAID5, and then divided into two virtual disks: Virtual Disk 1 named system, size 100GB, virtual Disk 2 named data, for the remaining 19.8TB capacity;

2 and the last disk as a global hot spare.

3 , the operating system is CentOS 6.7, the operating system is installed on the system disk 100GB space, after the installation of the operating system, you need to mount other disks to the/data directory.

Since our partition is already a GPT partition, can be directly operated, if the original partition is MBR partition, you need to use the command Mklabel GPT to create a disk label (partition table) to GPT, the middle will prompt to do damage data, enter Yes, continue; then use the Print command to view

Use the command mkpartprimary 0KB 19.7TB command to create a partition with a size from 0KB to 19.7TB; The intermediate warning content can be ignored, enter Yes, the second question about performance, input I select Ignore.

3, format, and Mount

After you have divided the area, you need to format the disk, using the command MKFS.XFS to format the disk in XFS format, as follows:
