free space.

sum/1048576}''`
No, you can''t fill all OSTs. Striping results in an even distribution,
which
means that you''re limited by the free space on the smallest OST.
Also, I agree with Andreas that we should not remove all files always - but in
this case, the file is large enough to cause -ENOSPC problems later if it stays
around. Therefore the ''rm'' at the end of the test is the
right thing to do.
