Finally the disks will be formatted and once the drive is mounted you should be welcomed with the familiar AutoPlay prompt. If you browse to Windows explorer you should also see that the new volume has the combined storage space of the three individual disks used to create it.

Administrators have great flexibility in coordinating their individual storage devices and creating logical storage devices that have greater performance or redundancy characteristics.
In this guide, we will go over a number of different RAID configurations that can be set up using an Ubuntu Throughout this guide, we will be introducing the steps to create a number of different RAID levels.
If you wish to follow along, you will likely want to reuse your storage devices after each section. This section can be referenced to learn how to quickly reset your component storage devices prior to testing a new RAID level. Skip this section for now if you have not yet set up any arrays. Warning This process will completely destroy the array and any data written to it. Make sure that you are operating on the correct array and that you have copied off any data you need to retain prior to destroying the array.
Check them every time to make sure you are operating on the correct devices. After discovering the devices used to create an array, zero their superblock to reset them to normal:. You should remove any of the persistent references to the array. At this point, you should be ready to reuse the storage devices individually, or as components of a different array. The RAID 0 array works by breaking up data into chunks and striping it across the available disks. This means that each disk contains a portion of the data and that multiple disks will be referenced when retrieving information.
As you can see above, we have two disks without a filesystem, each G in size. These will be the raw components we will use to build the array. To create a RAID 0 array with these components, pass them in to the mdadm --create command. You can automatically scan the active array and append the file by typing:. Afterwards, you can update the initramfs, or initial RAM file system, so that the array will be available during the early boot process:.
The RAID 1 array type is implemented by mirroring data across all available disks. Each disk in a RAID 1 array gets a full copy of the data, providing redundancy in the event of a device failure. To create a RAID 1 array with these components, pass them in to the mdadm --create command. If the component devices you are using are not partitions with the boot flag enabled, you will likely be given the following warning. It is safe to type y to continue:.
The mdadm tool will start to mirror the drives. This can take some time to complete, but the array can be used during this time. The second highlighted line shows the progress on the mirroring. Also, there are special utilities to help you create and maintain a RAID array. For example, Intel Rapid Storage Technology. You are free to choose between flexible data protection, RAID 1, 0, 5 and There is a brief description for every type. Select the one you prefer and click Next.
Give the volume name and select the disks that will make up your RAID. Check the disks and settings you need and click Next again. Configure advanced settings if necessary. I leave «default settings» for Volume Size and Array allocation. You will see the warning that «This action will permanently delete existing data on the following disks…».
If you have any important data there, save it to another location before you move on. The volume is created. That is why you need to open Disk Management. Immediately, you are informed that the disk must be initialized for Logical Disk Manager to access it.
Select partition style and click «OK». The utility shows that the disk is still being initialized — the duration of this process depends on disk capacity.
Using this tool makes it much easier to monitor your RAID status, And should any of the disks within this system fail, you will notice it at once.
This utility lets you see which particular disk has failed by using its serial number. On every disk, there is a sticker with that number. In the «Settings» tab, you can configure notifications in case of any problems and even specify an email address to send notifications automatically,.
