Hi,
i have an NAS F4-425.
There is one Raid 1 with 2x 8TB HDDs.
Now i like to expand with two new 8TB HDDs.
(How) can i expand the Raid 1 to Raid 10 without data lost?

Thanks

You can’t directly convert a 2-disk RAID 1 to RAID 10 on the F4-425 without rebuilding the array. Back up your data first, then create a new 4-disk RAID 10 and restore the data.
