>From 759a61519343c64066a5a14bb97447878aa1297e Mon Sep 17 00:00:00 2001 From: majianpeng <majianpeng@xxxxxxxxx> Date: Mon, 19 Mar 2012 15:59:04 +0800 Subject: [PATCH] md/raid5:Fix recover/replace stop and start repreatedly if handle stipe failed,because one disk had bad blocks. When raid5 recovering,then failed because one disk had bad blocks. The sync_request() return value which larger than 0 and set MD_RECOVERY_INTR.Because the statement if (test_bit(MD_RECOVERY_INTR, &mddev->recovery)) first call,so the mddev->curr_resync did not change. After the sync done,the mddev->curr_resync did not change.So the resync_thread will stop and start repeatedly.
