Software raid guide

If you are limited to resize your volume, you can utilize this program to move or resize the volume easily. Step 1. Step 2. Then you can drag the handle leftward or rightward to resize the volume. If you want to move the volume to the unallocated space, just move the whole handle to change the location.

After specifying the volume, click on OK to save the changes. Step 3. Click on Apply on the upper left corner to execute the operation. After that, you will be asked to restart your computer. You just need to follow the prompt. If you are also trying to figure it out, this post will provide you with a comprehensive analysis. Click to tweet. Here comes the end of the post.

We also appreciate any ideas left in the comment area. Download Partition Wizard. Read More. Tip: The basic RAID hardware that supports only striped , mirrored or other independent drives is relatively affordable.

Look Here! The 2 types of RAID are designed with fault tolerance that can sustain a loss of one disk in the set. Which is the safest RAID configuration?

It requires at least 3 hard drives and it can work with up to 16 drives. The data blocks are striped across the drives with parity in all disks. RAID arrays provide enhanced data protection, but their extra drives cannot be considered as backups. In other words, you still need to back the data up even if your main drive is a RAID array. Lower price in general. The basic RAID levels are supported by many operating systems. Perform adequately for basic RAID levels.

Performance may be affected by complex RAID levels. 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,.

Other settings let you decide on cleaning cache and use of caching options, verifying and checking any data inconsistencies, and more. This is how you can create any of the available software RAID types in Windows Server operating system, in an easy and effortless way. Read more. To recover data from a network storage, you need to take out the disks and connect them to the computer. After that, start the utility and select the disks that used to make up the RAID system.

The utility will analyze the disks to calculate the settings which were used to create that array. Select the Chunk Size and, if applicable, the Parity Algorithm. The optimal chunk size depends on the type of data and the type of RAID. More information on parity algorithms can be found with man 8 mdadm when searching for the --layout option.

If unsure, stick with the defaults. Choose a Role for the volume. Your choice here only affects the default values for the upcoming dialog. They can be changed in the next step. If in doubt, choose Raw Volume Unformatted. The content of the Options menu depends on the file system. Usually there is no need to change the defaults. Under Mounting Options , select Mount partition , then select the mount point.

Click Fstab Options to add special mounting options for the volume. Click Next , verify that the changes are listed, then click Finish. Working with these names can be clumsy. Note that this will only apply to RAIDs configured after the change to the configuration file. Not all tools may support named RAID devices. If a disk fails, shut down your Linux system and replace the defective hard disk with a new one partitioned the same way.

Replace X with your particular device identifiers. Although you can access all data during the rebuild, you might encounter some performance issues until the RAID has been fully rebuilt. There are several reasons a disk included in a RAID array may fail.

Here is a list of the most common ones:. In the case of the disk media or controller failure, the device needs to be replaced or repaired. If a hot-spare was not configured within the RAID, then manual intervention is required. In the last case, the failed device can be automatically re-added by the mdadm command after the connection is repaired which might be automatic.

Under some circumstances—such as storage devices with the internal RAID array— the connection problems are very often the cause of the device failure.

In such case, you can tell mdadm that it is safe to automatically --re-add the device after it appears. Wild cards can be used to identify groups of devices.
