On a gluster volume with 100GB if we try to create a gluster-block of size 100GB with pre-allocation, block creation succeeds but it silently fails to allocate the correct sizes for the shards on the posix xlator.

Because of this when writes happen on a pre-allocated block device, writes fail with ENOSPC which shouldn't happen for preallocated files.
