I had a massive data lost with my last raid5 (with 1 spare out of 4 hdds) using mdadm, because 2 drives failed within 1 day (unfortunately).
Now I bought new hdds and now have a total of 6 hdds. I want to build a new raid which can handle the loss of two drives, independant of which 2 are failing.
HW-Raid and LVM is no option in my environment.
I had an mdadm raid10 in mind (but have no idea how do that practically): - 6 devices in common - 3 spares. So I'd have a loss of 50% of space but could handle 2 faults
May anyone has an idea how to do that or another approach?
