There is another issue, i updated xfsprog from 2.10.1 to 3.1.5, and
found i could not make the xfs filesystem when the logical volume size
large than 8TB with command mkfs.xfs -f -i size=512
/dev/vg+vg00+20120406101850/lv+nxx+lv0000, this command seems hang, it
did not return for a long time, is there any parameter i should

Thank you very much

Best Regards,
Daobang Wang.
