I'll add two questions that're not answered by the Wiki too.. :-)

1) If you add a second disk to an existing btrfs filesystem, can you get it to 
set it up as a RAID-1 arrangement rather than just rebalancing the metadata 
and then striping ?

2) With the concerns that people have about SSD reliability (hi Val :-) !) 
would it make sense to set up two equal sized partitions on the SSD and use 
RAID-1 across them, or can you tell btrfs to keep multiple copies of the data, 
a la ZFS ?

cheers!
Chris
