Sure, replace the bad drive and rebuild build the mirror. Or add 2 drives, using one to replace the bad one and the other as a hot spare. Then if one of the 2 drives in the mirror fails again, the hot spare will take over for it.
one thing thats always bugged me about md raid when its mirrored per partition... say you have /dev/sda{1,2,3} mirrored with /dev/sdb{1,2,3} ... if /dev/sdb2 goes south with too many errors and mdraid fails it, will it know that b{1,3} are also on the same physical drive and should be failed, or will it wait til it gets errors on them, too?
