Hi, folks?

I would like to know if current RAID1 support or willing to support a
RAID1 with a write only device? For example, u can setup 2 disks to form
a raid1, you fork 2 writes to both disks while you only read from one.
this will be very useful for logging purpose or replication.

This functionality has been discussed, but have not been implemented
in a released kernel yet.
