But the sync takes a while (> 4 hours, I don't remember > exactly). Are there any ways to speed up the process ? MD will adjust its speed while initializing, thus the fastest way is to do nothing on the system, avoiding any other disk IO. This will cause MD to use max bandwidth. One thing you can do for testing is to create a smaller array which will of course initialize faster. Please run mdadm -E /dev/sdX for all RAID disks before and after reboot and watch out for differences.
