Hi
    I transfer large amounts of data to IET target using the open-iscsi, exp, 
copy 10G`s  file to IET target. But there is a problem.when the end of the file 
is copied, umount the disk and logout,the size of file that is in the IET 
target  is less than the original file,the log follows:
      [root@testGW imgs]#
