After I restored the data that resided on one partition of
the rz28 (apx 1gb) onto the partition of rz1df (apx 4gb)
I ran (du -k -s) and it showed 2.7gb. Now that 2.7gb of
files came from a filesystem of about 1gb by doing a
cp -Rp rz28partition rz1dfpartition.
Would changing the partition size from 1gb to 4gb, change
the minimum amount of drive space required for "each" file
that much it would increase in size by 1.7gb?
Yes, I do realize these drives are not partitioned for their
full capacity, as some have pointed out.
Thanks
George
