I'll still get ready for another failure. Will read up on the best methods to have an encrypted filesystem on top of raid-1.
I'm pretty sure that if you tell the Fedora installer to build an encrypted RAID1 system, you'll get exactly what I described previously. In detail:
sda1 - 512MB sda2 - remainder of disk
sdb1 - 512MB sdb2 - remainder of disk
md0 - RAID1 including sda1 and sdb1 md1 - RAID1 including sda2 and sdb2
/boot - filesystem on md0
luks-$(uuid) - encrypted block device on md1
pv.01 - LVM2 physical volume on luks-$(uuid)
fedora_$(hostname) - LVM2 volume group including "pv.01"
swap - swap on logical volume root - filesystem on logical volume home - filesystem on logical volume
If you replace a disk, you'll need to partition it correctly and "mdadm --add" it to the two RAID volumes.
If you manually set up some other layering, replacing a disk will probably be more involved.
