1 Answer

First prepare the disk with gdisk since fdisk can not do a partition larger than 2TB.
Run sudo mdadm –create –verbose /dev/md0 –force –level=1 –raid-devices=1 /dev/sdb1 .
Format the newly created RAID partition and copy everything from the original disk to this partition.

Does Linux support RAID?

The 0.90 RAID support is available as patches to Linux-2.0 and Linux-2.2, and is by many considered far more stable that the older RAID support already in those kernels.

What is RAID 5 configuration?

RAID 5 is a redundant array of independent disks configuration that uses disk striping with parity. RAID 5 groups have a minimum of three hard disk drives (HDDs) and no maximum. Because the parity data is spread across all drives, RAID 5 is considered one of the most secure RAID configurations.

What are the different RAID levels in Linux?

Different RAID levels are defined based on how mirroring and stripping are required. Among these levels only Level 0, Level1 and Level5 are mostly used in Red Hat Linux. This level provides striping without parity.

Why do you need two disks for RAID 1?

A minimum two number of disks are more required in an array to create RAID1 and it’s useful only, when read performance or reliability is more precise than the data storage capacity. Mirrors are created to protect against data loss due to disk failure. Each disk in a mirror involves an exact copy of the data.
