First of all a big fat warning to not just do this whenever you feel like it.

The resynchronization of your RAID group is there for reason!
(bad disk, bad block, raid out of sync etc).

Having said that, If your array is md2 then

echo "idle" > /sys/block/md2/md/sync_action

You can determine which is your array by using:

cat /proc/mdstat


In the example below you'll see that md2 is my RAID-6 array ...

[~] # cat /proc/mdstat                                                      
Personalities : [linear] [raid0] [raid1] [raid10] [raid6] [raid5] [raid4] [multipath] 
md2 : active raid6 sdg3[0] sde3[7] sdf3[8] sdd3[10] sdc3[4] sdh3[3] sdj3[9] sdi3[1]
      23382380544 blocks super 1.0 level 6, 512k chunk, algorithm 2 [8/8] [UUUUUUUU]
      bitmap: 12/30 pages [48KB], 65536KB chunk

md1 : active raid0 sda3[0] sdb3[1]
      956863488 blocks super 1.0 512k chunks
md322 : active raid1 sde5[7](S) sdf5[6](S) sdd5[5](S) sdc5[4](S) sdh5[3](S) sdj5[2](S) sdi5[1] sdg5[0]
