  The DSPOBJD is inappropriate for comparing the data sizes.  Use 
the "Data space size" from member portion of the DSPFD.  Also the 
manner of /copy/ influences the dataspace size so until the amount 
of data becomes very large, simple comparisons are not generally 
valid.  Already clarified in other posts, the use of RGZPFM to 
reorganize the data in both copies can assist to make such size 
comparisons more accurate; consider that the auxiliary SID has 
different rules for reorg than the primary data segments, so there 
may still remain some issues is simple comparisons.  In another post 
I note that two reorganize requests may truncate the aux SID.  Doug 
posted even better information, and the various SIZE values in the 
DST MI object dump will be most accurate to pinpoint individual 
pieces of storage being taken.
