[leo@thinkpad-leo DR]$ ls -sh dr_replay/
total 11M
   0 build     6.5M core.2328  4.0K env.sh      16K out      4.0K run2.sh   12K test_main
4.0K build.sh  3.2M core.6597  400K memcached  4.0K run1.sh     0 sym      4.0K test_main.c




Additional info:

If I copy dr_replay folder to other places, the problem does not occur again.
I am using XFS.

While this is confusing, there is no inconsistency here.

Notice the first column is 6.5M in the `ll -sh` case, which corresponds to the `ls -sh` reported disk usage for the sparse core file.

Once you copy the file you're probably removing the sparseness (though that may be another issue as cp should maintain the sparseness if possigle).

I see. Thank you.
