>From ancient times SG_ALL was defined as 0xff = 255. Rather likely for that reason we see lots of IO requests of size 1020 from drivers that do not support sg-chaining yet. And IO sizes of 1020 are a nightmare for DDN hardware. Is there a chance to increase that to 256 by default? Lustre includes a kernel patch to that for RHEL5 kernel and it greatly helps to get correct IO sizes.
