RAID 10 is a popular RAID level that provides both high performance and data redundancy by combining the best of RAID 0 and RAID 1 configurations. In this tutorial, we will guide you through the process of how to create a RAID 10 setup on OpenSUSE.
Before we begin, make sure you have:
- A fresh installation of OpenSUSE.
- Four hard drives with equal capacity.
- Root access to your OpenSUSE system.
If you need help with any of these steps, you may refer to the following resources:
How to Create RAID 10 on OpenSUSE
Install Required Packages
First, update your system packages by running the following command:
Next, install the mdadm package, which is a necessary tool for managing RAID arrays:
zypper install mdadm
Create Partitions on Each Drive
In this step, you will create a new partition on each of the four hard drives. You can use the
fdisk tool to do this. First, identify your drives using the following command:
Assuming your drives are named
sde, run the following commands to create a new partition on each drive:
fdisk /dev/sdb fdisk /dev/sdc fdisk /dev/sdd fdisk /dev/sde
After running each command, follow these steps:
nto create a new partition.
pto choose a primary partition.
1to create the first partition.
Entertwice to accept the default values for the first and last sectors.
tto change the partition’s system ID.
fdto set the partition type to Linux RAID autodetect.
wto write the changes and exit.
Create RAID 10 Array on OpenSUSE
Now that you have created the necessary partitions, you can create the RAID 10 array using the
mdadm --create /dev/md0 --level=10 --raid-devices=4 /dev/sdb1 /dev/sdc1 /dev/sdd1 /dev/sde1
This command creates a new RAID 10 array (
/dev/md0) using the four partitions you created earlier. You can check the progress of the RAID creation by running:
Create a Filesystem on the RAID Array
Once the RAID 10 array is created, you can create a filesystem on it. In this tutorial, we will create an ext4 filesystem:
Mount the RAID Array
Now that you have created a filesystem on the RAID 10 array, you can mount it. First, create a directory where you want to mount the RAID array:
Then, mount the RAID array:
mount /dev/md0 /mnt/raid10
This command mounts the RAID 10 array (
/dev/md0) to the
Update /etc/fstab to Automount RAID Array
To ensure that the RAID array is mounted automatically at boot, update the
/etc/fstab file. First, obtain the UUID of the RAID array by running:
Copy the UUID value and open the
/etc/fstab file using your preferred text editor:
Add the following line at the end of the file, replacing
UUID_VALUE with the UUID you copied earlier:
UUID=UUID_VALUE /mnt/raid10 ext4 defaults 0 0
Save the file and exit the text editor.
Verify RAID Array Status
You can verify the status of your RAID 10 array by running the following command:
mdadm --detail /dev/md0
This command will display detailed information about the RAID 10 array, including the status of each drive and any potential issues.
Congratulations! You have successfully created a RAID 10 array on OpenSUSE. For more tutorials on managing your OpenSUSE system, check out the following articles:
