i don't know the mdadm equivalent, but i do raidhotremove followed by raidhotadd to get around that issue. if you look at /proc/mdstat after the failure, you'll probably see the drive is still part of the array, but just marked as down. raidhotremove tells the system it is gone and then you can add it back. - To unsubscribe from this list: send the line "unsubscribe linux-raid" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
