From 3eda22d19b76b15ef3420b251bd47a0ba0127589 Mon Sep 17 00:00:00 2001 From: NeilBrown Date: Fri, 26 Jan 2007 00:57:01 -0800 Subject: [PATCH] [PATCH] md: make 'repair' actually work for raid1 When 'repair' finds a block that is different one the various parts of the mirror. it is meant to write a chosen good version to the others. However it currently writes out the original data to each. The memcpy to make all the data the same is missing.
