Symptoms:
	PHKL_29335:
	( SR:8606307276 CR:JAGae70309 )
	VxFS returns vx_nospace on an NFS write or when writing
	to a sparse file on a heavily fragmented filesystem, even
	though the filesystem has sufficient disk space.

Defect Description:
	PHKL_29335:
	( SR:8606307276 CR:JAGae70309 )
	If writes to a file are non-sequential or random, as in the
	case with NFS and sparse files, VxFS may fail to get an
	extent of a certain size when writing to a hole due to
	excessive fragmentation.

	Resolution:
	VxFS  now manages the file on disk layout three and above
	such that writing to a hole in the file can allocate
	multiple smaller sized extents.

Enhancement:
	No
