Re:Understanding RAID: How performance scales from one disk ... by mohammedhdotio on Friday April 17, 2020 @03:02PM (#22901877)
Hello and thanks for your time.

- I've got 1 HDD failure on RAID10 4 x 10TB HDDs, I had to take the system down to do RAID10 rebuild. because running server with huge I/O slowdown the rebuild and I had my fears of second HDD failure. (I had to take the system down anyway). RAID didn't help in my usage scenario.

- I guess deduplication fixes this already.

- Any advice on ways fixing this and preserving my RAID0 usage scenario?

Broadly speaking, you have two options. One is, make the server faster so that it can keep operating during a rebuild. You could do this by adding more drives. The other option is, add a second server to handle the load while you fix the first.
