Hope you checked the Roadmap, we have it coming in 1.5 release (planned to
it ready by yearend).

Scheduler is not the term you may be looking at... check AFR (automatic file
replication), and yes, if you are using, you can take out the node when
cluster is active.

Well, at the rate of 1GB per minute, you will hit the disk speed, hence
stripe is better option. But with Stripe translator you will not be able to
take out the nodes.
