yep it should handle this just fine, without dropping into degraded mode.
The kernel will print a warning on the next reboot and will fix up device
names automatically. You should adjust the raidtab just in case you need
it later (say for raidstart).

mkraid -f --force-resync is currently unsafe if you do it for an array
that is already in degraded mode. With the new code you should never need
it anyway.
