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=20
set it up as a RAID-1 arrangement rather than just rebalancing the metadata=
=20
and then striping ?

2) With the concerns that people have about SSD reliability (hi Val :-) !)=
=20
would it make sense to set up two equal sized partitions on the SSD and use=
=20
RAID-1 across them, or can you tell btrfs to keep multiple copies of the da=
ta,=20
a la ZFS ?

cheers!
Chris
