md0 is probably your boot partition which is smaller and has very little data written to it. md1 on the other hand is probably your / where all software is installed. Unless you have a very high performance disk controller/drives, you'll usually find that it cannot keep up with initial format of the array, then the subsequent dumping of data to it during installation. Upon reboot, it'll simply restart the sync process and finish happily. I've seen this on nearly every md RAID1 system I install on.
