    Cannot replace a faulty disk using mdadm raid1

    I have a Software Raid 1 array that I build a couple years ago. One day, after I loss current, the array became corrupted. One the drive was corrupted so, I removed it from the array and rezeroed it.
    Now, I want to re-add it to the array. When I'm doing the following command :
    mdadm --add /dev/md0 /dev/sdb1
    The command is executed and I can see if I run --detail that the drive is rebuilding but this stays for a couple of seconds and then I get the following :


    I really don't know how to resolve this issue

    When something goes corrupt...there is a reason most times...

    Start by looking up the S.M.A.R.T. statuses for the disks.
