I think it's safe that unless you reshape (add disks or change levels ie; raid5 to raid6 etc. If you do this you really then should get the latest and greatest kernels and mdadm package and make sure you have a good backup and are not relying on your server before doing anything). The biggest issue is actually booting working properly as grub2's raid support is a bit broken for some scenarios. Regards, -- Daniel Reurich.
