Description
See: http://permalink.gmane.org/gmane.comp.file-systems.ceph.devel/7282
If a user (on tmpfs, in this case) specifies a journal size which is larger than the available space, the OSD will crash when it runs out of space.
There are checks in the FileJournal to detect if the block device is smaller than the set journal size (and bail out), but I don't see any for files. We should add them.

for files, i think the right approach is to fallocate(), which will reserve the space. we shouldn't have to look at e.g. statfs(2), which isn't reliable for this sort of thing anyway.

this has called fallocate(2) for a while now.
