From c4a39551451666229b4ea5e8aae8ca0131d00665 Mon Sep 17 00:00:00 2001 From: Jonathan Brassow Date: Tue, 25 Jun 2013 01:23:59 -0500 Subject: MD: Remember the last sync operation that was performed MD: Remember the last sync operation that was performed This patch adds a field to the mddev structure to track the last sync operation that was performed. This is especially useful when it comes to what is recorded in mismatch_cnt in sysfs. If the last operation was "data-check", then it reports the number of descrepancies found by the user-initiated check. If it was a "repair" operation, then it is reporting the number of descrepancies repaired. etc. Signed-off-by: Jonathan Brassow Signed-off-by: NeilBrown --- Documentation/device-mapper/dm-raid.txt | 1 + 1 file changed, 1 insertion(+) (limited to 'Documentation/device-mapper') diff --git a/Documentation/device-mapper/dm-raid.txt b/Documentation/device-mapper/dm-raid.txt index 2bb3a6823dc7..ef8ba9fa58c4 100644 --- a/Documentation/device-mapper/dm-raid.txt +++ b/Documentation/device-mapper/dm-raid.txt @@ -223,3 +223,4 @@ Version History 1.5.0 Add message interface to allow manipulation of the sync_action.
