Hi,
my 2cent,
maybe with lower range (like 100MB) of random io,
you have more chance to aggregate them in 4MB block ?
Yes maybe. If you have just a range of 100MB the chance you'll hit the
same 4MB block again is very high.

Hi everyone,
just wanted to check if this was the expected behavior -- it doesn't
look like it would be, to me.
What I do is create a 1G RBD, and just for the heck of it, make an XFS on it:

Hey guys,
Thanks for the problem report. I've created an issue to track it at
http://tracker.newdream.net/issues/2687.
It looks like we just assume that if you're using a file, you've got
enough space for it. It shouldn't be a big deal to at least do some
startup checks which will fail gracefully.

Applied, thanks!
I think the mtab.c should eventually move to ceph-fs-common to mirror the
debian package structure (mount.ceph, cephfs tool). It's probably not
worth replacing fiemap.cc, though, until someone actually makes a plugin
interface and wants to link to the ceph-osd binary that
