I've configured a raid10,f2 with an external bitmap: mdadm --grow --bitmap=/md0.bitmap /dev/md0 The root ('/') filesystem is NOT on the raid. It's a normal partition (/dev/sdb1, the boot device actually). After reboot, cat /proc/mdstat does not show a bitmap. What's up with that? That sure doesn't seem right. -- Jon -- To unsubscribe from this list: send the line "unsubscribe linux-raid" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
