How to Create Raid6 on ZimaOS?

Introduction

Currently, ZimaOS supports RAID0/1/5, but we understand that many users require RAID6 for enhanced redundancy. To address this, we’ve prepared a step-by-step guide for creating RAID6 through the command line. Please follow the instructions below.
We look forward to accelerating our support for more RAID levels in the future!

Tips

If the system is rebooted, you’ll need to reassemble the RAID6 array.

Prerequisites

  1. You will need at least four hard drives.

  2. You need to learn how to get to the command line page by clicking on this.

  3. You need to run the commands in the tutorial with superuser privileges (root privileges). You can use sudo to elevate privileges, such as sudo mkfs.ext4 /dev/md0

  4. Use the command lsblk to check the available hard drives.

  5. If MOUNTPOINTS has a mount point, you need to cancel it with the following command.

    umount /dev/sda

Steps to Create RAID6

  1. Create the RAID6 array with at least four drives using the following command:

    mdadm -Cv /dev/md0 --level=6 --name=foldername --raid-devices=4 /dev/sda /dev/sdb /dev/sdc /dev/sdd --run --homehost=zimaos

    /dev/md0 is the name of the new RAID device.

    --level=6 indicates you’re creating a RAID6 array.

    --name=foldername specifies the name of the RAID array.

    --raid-devices=4 tells the system to use four hard drives.

    /dev/sda /dev/sdb /dev/sdc /dev/sdd are the drives participating in the array.

  2. Format the RAID using the following command:

    mkfs.ext4 /dev/md0

  3. Create a directory for mounting the RAID:

    cd /media
    mkdir foldername

  4. Mount the RAID using the following command:

    mount -t ext4 /dev/md0 /media/foldername

  5. Once created, enter the path in the web-based File to display it

Notice:

If the system is rebooted, you’ll need to reassemble the RAID6 array:

mdadm -Av /dev/md0 /dev/sda /dev/sdb /dev/sdc /dev/sdd
mount /dev/md0 /media/foldername
