From 7b0bb5368a7195606eca475d9f4e291ab7227052 Mon Sep 17 00:00:00 2001 From: "Gabriele A. Trombetti" Date: Wed, 28 Apr 2010 11:51:17 +1000 Subject: md/raid6: Fix raid-6 read-error correction in degraded state Fix: Raid-6 was not trying to correct a read-error when in singly-degraded state and was instead dropping one more device, going to doubly-degraded state. This patch fixes this behaviour. Tested-by: Janos Haar Signed-off-by: Gabriele A.
