Performance Test Results
With RAID :
Command: dd if=/dev/md0 of=/dev/null bs=4M status=progress; sync
Result: 510 GB copied in 149 seconds at a rate of 3.4 GB/s.
Without RAID (Single Disk)
Command: sudo dd if=/dev/nvme0n1 of=/dev/null bs=4M status=progress; sync
Result: 255 GB copied in 111 seconds at a rate of 2.3 GB/s.
For each disk you want to include in the RAID configuration:
Run: parted /dev/sdX mklabel gpt to create a new GPT label
Create a primary partition with: parted /dev/sdX mkpart primary ext4 0% 100%
Set the RAID flag with: parted /dev/sdX set 1 raid on
Use mdadm to create the RAID array:
mdadm --create --verbose /dev/md0 --raid-devices=<number of disks> --level=0 /dev/<partition of first disk> /dev/<partition of second disk> <more disks>
|
Format RAID device with: mkfs.ext4 /dev/md0
/dev/md0 is used because in the previous command we created it with the name /dev/md0 |
Run blkid to ge the UUID of the /dev/md0 partition
Example: UUID="2ff3d24d-c123c-43d5-41ed-627bcdf54154"
Open /etc/fstab using vi /etc/fstab
Add the Line <Your UUID> /home ext4 defaults 0 1
Replace <>Your UUID> with the actual UUID from the previous step
You can also change /home which is the destination point to mount the RAID disk
Run mount -a to mount all filesystems
Verify with df -h to see if the filesystem got mounted
Always ensure you have a backup of your data before making changes to disk or configurations. |
