RAID 6 with 2 drives missing

Post by lcoughey »

I am quite sad that the latest version of ReclaiMe PRO still doesn't support 2 missing disks on a RAID 6.

Here is the response from RecaiMe when I sent the question to them directly.
The problem with two disks missing is that you need to know how to calculate Q parity. P is always XOR but different controllers use different methods of calculating Q. Some time ago we discussed the problem and decided not to support 2 missing disk configuration. At the moment we do not have plans to support this.
This is what I figured, but it is nice to have an official answer now.
