Ramadan Kareem Yousuf.
    What I would do is shrink partition 5 by 100M then create a new
    ef02 partition in the freed space. This should be completely safe
    since it is just a swap partition and contains no permanent data.
    Do this on both drives after stopping swap (swapoff) then /dev/md1.
    There is no need for RAID on the ef02 partition.
Thanks for the wishing the Ramadan Kareem :)
Thanks for your tip. however what i am looking is more easy way. as 
Pascal is saying i already have free space in my new drive and there 
is no need for shrinking a partition. which is i think dangerous at 
this point because only 1 drive is left. if i loose the data i have to 
go back to my archive and restore all the data from my old backup 
drive which going to be a headache.
so what i am trying to find out if creating a new partition is 
sufficient that i will choose that route.
Thanks,
Yousuf
