Can anyone here shed a little more light on how to
monitor the disk
activity while transferring data?
Not sure if this would work, but first thing I can think of is:
1) Calculate the amount of data to transfer (du command.)
2) Find out the remaining free space in the target unit (df command.)
3) Calculate the remaining free space when the copy is done.
4) Begin copy.
5) Periodically monitor the free space.
HTH,
Luis
