Description

Right now, you need to specify all layout options in cephfs (of the stripe unit, stripe count, and block size, anyway). I'm pretty sure this is unintentional -- it at least makes sense to change the stripe unit and count without changing the block size (ie, to actually turn on striping in the first place).

At least figure out why it's set up that way, and if appropriate, (1) change it, (2) add tests for it to file_layout.sh.

(This may actually be a kclient issue, too.)

And you also need to specify these even if you only want to set the pool. :(

This is going to be related to #1446, obviously. I'll take both.

The in-kernel code rejects any layout that doesn't set the stripe unit (and if you set the object_size it makes sure they'll match up when striping). Which probably explains the EINVALs.
