If you are sure that you have created the array with the proper order of disks (They MUST be in the correct order! Your disks may have changed their names for some reason -- verify that they are in order!!) and that you have assembled them properly, I would suggest you run a tool called "testdisk" You may have a corrupt filesystem, and testdisk would try to fix it. Also, to make sure that you have assembled the array in the correct order, and if the filesystem can't be fixed if it's corrupt, use a file-recovery tool like foremost or magicrescue and see if they recover your data.
