Now to verify the status of RAID level, run the following command.

The partition has been done successfully. Mdadm: Defaulting to version 1.2 metadata Desktop]# mdadm -create /dev/md5 -level=stripe -raid-devices=2 /dev/sd1 Execute the following commands along with its options. Mdadm: No md superblock detected on /dev/sdc1.Ĭreate the md device and select the RAID levels in the command. Mdadm: No md superblock detected on /dev/sdb1. The output shown below states that the disks have no previous RAID partition in the target system. Execute the following command to check it. Next check the block details for any previous configuration that has been made in the disk. Repeat the above mentioned steps to create partition for another block and provide the Hex code for the partition as ' fd' which is the Linux Raid Autodetect assigned to the partition.

Partition 1 of type Linux and of size 5 GiB is set Enter the following set of commands to create the partition. Next create the partition for two disks by executing the following command. Now check the if the device is available to configure RAID by running the following lsblk command. Loading mirror speeds from cached hostfile Run the following command and press y to continue with the installation. To proceed with the configuration process, install the mdadm package which is a RAID managing tool in the target system for easier partitioning of disks. To configure RAID 0, a minimum of two hard disks are required. Both disks appear as a single partition, so when one of them fails, it breaks the array and results in data loss. There is no added redundancy for handling disk failures, just as with a spanned volume. The capacity of a RAID 0 volume is the sum of the capacities of the disks in the set, the same as with a spanned volume. RAID 0 consists of striping, without mirroring or parity. This tutorial covers the configuration procedure of RAID 0 on CentOS 7. The two types of RAID are hardware RAID and software RAID. It offers an excellent performance and this performance will vary depending on the RAID level. The disks are connected together to make a logical volume. The data is distributed across the drives in one of several ways, referred to as RAID levels, depending on the required level of redundancy and performance. RAID (Redundant Array of Independent Disks) is a data storage virtualization technology that combines multiple physical disk drive components into a single logical unit for the purposes of data redundancy, performance improvement, or both.
