* The mdadm raid metadata does not modify the individual filesystems that it's maintaining copies of. Each copy is still a valid free-standing filesystem as if it were never part of an array. This is not necessarily true for other raid implementations but it is true for linux mdraid. This means that when the bios boots grub or other boot loader, the bootloader does not have to include a raid driver to read the partition or the filesystem, it can read any individual raid1 volume as a plain filesystem on a plain partition on a plain disk.
And this fact saved my bacon on two occasions. Both in the same machine, a week apart from each other, when two drives from the same lot failed withing one week of each other.
