On an RH5885 server, two 600 GB SAS disks are grouped as RAID 1 serving as the system disks (assuming that RedHat 6.2 is installed) and four 4 TB disks are grouped as RAID 5 serving as the data disks. After the system installation is complete, how do I use RAID 5 as data disks?
1. Run the fdisk -l command to query the partition information. The /dev/sdb disk is not partitioned, as shown in the following figure.
2. Run the parted /dev/sdb command and partition the /dev/sdb disk in the GPT style.
Note that all the information pointed by red arrows in the following figures must be entered.
3. Run the fdisk -l command to query the partition information again. It is found that the partition system of the /dev/sdb1 disk has been changed to GBT, as shown in the red circle.
4. Format the disk into a file system and mount the disk to the required directory for data use. You can run the df -h command to query the mounting status.
