OK
I did the following:
1. Remove sda from raid (using mdadm) 2. Run dd (dd if=/dev/zero of=/dev/sda bs=512 count=1000) 3. Copy the current disk partition table (sfdisk -d /dev/sdb | sfdisk /dev/sda) 4. add disk to raid (using mdadm) 5. reinstall grub (using grub command) 6. run grub-install /dev/sda 7. Reboot
and now it's working :)
I did all the above steps before except step 2, it seems I need to clear the disk with dd
Thank you Markus for your reply.

Hello Everyone
I have a remote CentOS 6.4 server (with KVM access), when I received the server it was running with LVM on single disk (sda)
I managed to remove LVM and install raid 1 in sda and sdb disks
the mirroring is working fine, my only issue now is that everytime I reboot the server I got the grub command line and I have manually boot using comand
...
I tried almost everything I can find in the internet.
You did reinstall grub? Something like (or similar)
$ grub-install /dev/sda $ grub-install /dev/sdb
Note: each disk (sda & sdb) is 2TB size, could this be the problem?
No. I do not think so.
