Nope. Actually sdb6 is disk 1, sda6 is disk 0, which means that sdb6 is
the one that is non-operational, as Jeroen originally said.


Jeroen, in order to be able to hot-add, you must first raidsetfaulty,
then hot-remove the disk, then hot-add it. But, you should probably
first check your system log to see why the array is not syncing. The
hot-add may not help, depending on what the problem is.
