XFS speculative preallocation is not permanent and the extra space is freed up eventually. It can be sped up via procfs tunable: http://xfs.org/index.php/XFS_FAQ#Q:_How_can_I_speed_up_or_avoid_delayed_removal_of_speculative_preallocation.3F. We could also tune the allocsize option to a low value like 4k so that glusterfs quota is not affected. FWIW, ENOSPC is not the only fallocate problem in gluster because of 'iatt->ia_block' tweaking. It also breaks the --keep-size option (i.e. the FALLOC_FL_KEEP_SIZE flag in fallocate(2)) and reports incorrect du size.
