You have to backup the data somewhere else while you create the RAID because it involves a change of partition type and loss of the data in the current filesystem, ext3 I suppose.

Also it's not recommended procedure to run a RAID1 in degraded mode, which is what you propose to do when you remove sdb.

And booting is a separate issue. At boot time, GRUB knows nothing about RAID. So each disk must have its own bootloader. Lots of tricky issues there. Many people get around it by having a non-RAID /boot partition.

Why not just rsync the second disk to the first at regular intervals?
