Hi folks I have a raid5 array that contain 4 disk and 1 spare disk. now i saw one disk have sign of going fail via smart log. so i am trying to do this 1) pull that disk (A) out 2) using dd to copy that disk (A) to another same one (B); 3) put disk (B) back to raid5 and assume that bitmap can help me resync quickly. now my question is 1) can this achieve my goal? 2) is there any better/correct way? thanks!
