From 91a2f194faad281cda0a16f2324e55ba8ce76968 Mon Sep 17 00:00:00 2001 From: NeilBrown Date: Thu, 15 Dec 2011 17:25:59 +1100 Subject: [PATCH] md/raid1: Mark device replaceable when we see a write error. Now that Replaceable drives are replaced cleanly, mark a drive as replaceable when we see a write error. It might get failed soon so the Replaceable flag is irrelevant, but if the write error is recorded in the bad block log, we still want to activate any spare that might be available.
