raidpycovery supports raid4 and repetitions


Just wanted to announce that I just tagged/pushed version 2.01 of raidpycovery which now supports raid4 and also repetitions (like the one an HP SmartArray P410i displayed).

Repetitions works this way.On a normal RAID5 (left async) you would see something like this:
A0 B0 C0 D0 X0
A1 B1 C1 X1 D0
A2 B2 X2 C2 D2
A3 X3 B3 C3 D3
X4 A4 B4 C4 D4
A5 B5 C5 D5 X5

On a raid with 2 "repetitions" you would see:
A0 B0 C0 D0 X0
A1 B1 C1 D1 X1
A2 B2 C2 X2 D2
A3 B3 C3 X3 D3
A4 B4 X4 C4 D4
A5 B5 X5 C5 D5

You get the idea, right? On the raid5 I broke last weekend the controller did 16 repetitions.

Repository for the project is here.
