From b1581566183f310abbd2d384a9079d4039faca05 Mon Sep 17 00:00:00 2001 From: NeilBrown Date: Sun, 31 Jul 2005 22:34:50 -0700 Subject: [PATCH] [PATCH] md: make sure raid5/raid6 resync uses correct 'max_sectors' The default resync_max_sector is set to "mddev->size << 1". If the raid-personality-module updates mddev->size, it must update resync_max_sectors too.
