Hi,
i’ve a pool named DATA formed by one 4TB WD RED, i want to create a simil RAID 10.
I will add a new vdev 4TB WD RED to create a stripe of 2 disk and a total of 8TB Pool.
After this i want add another 2 disk 4TB each in stripe mode and expand with other 8TB STRIPE.
Is this possible ? New POOL will be 8TB “raid 10” ? correct ??
Thank you in advice
You can add a second 4 TB drive as a mirror (NOT Stripe) to your vdev, to give you the same amount of space, but with redundancy. Then add another vdev, with 2 extra drives as another mirror to your pool. This will then give you 8 TB of total space.
