From 24dd469d728dae07f40c5d79ea6dedd38cdf1a30 Mon Sep 17 00:00:00 2001 From: NeilBrown Date: Tue, 8 Nov 2005 21:39:26 -0800 Subject: [PATCH] md: allow a manual resync with md You can trigger a 'check' with echo check > /sys/block/mdX/md/scan_mode or a check-and-repair errors with echo repair > /sys/block/mdX/md/scan_mode and read the current state from the same file. Note: personalities need to know the different between 'check' and 'repair', but don't yet. Until they do, 'check' will be the same as 'repair' and will just do a normal resync pass.
