[Hyperic-hq-discuss] Directory Usage... Differences on results...

[Marcello de S. <mar...@gm...>]

I'm trying to verify how close the values from the command line "du" and the implementation class "Du". I don't know if that is the result of using the commands under a virtual machine, but the values differ...

* Sigar du execution
>$ /usr/lib/jvm/java-6-openjdk/bin/java -Djava.library.path=/u1/svnedge/replica_admin/SvnEdge/ext/sigar -classpath /u1/svnedge/replica_admin/SvnEdge/lib/sigar.jar org.hyperic.sigar.cmd.Du /u1/svnedge/production-tests/1.1/csvn/data/repositories/ddd

* Sigar Du execution output
73110   /u1/svnedge/production-tests/1.1/csvn/data/repositories/ddd

* Linux du command execution
>$ du -sb /u1/svnedge/production-tests/1.1/csvn/data/repositories/ddd

* Linux du command output
77206   /u1/svnedge/production-tests/1.1/csvn/data/repositories/ddd

I'm running these commands under a VMWare image running the following OS.

# Arch: i686
# Name: Linux
# VendorName: Linux
# Description: Ubuntu 10.04
# VendorVersion: 10.04
# Machine: i686
# Vendor: Ubuntu
# VendorCodeName: lucid
# PatchLevel: unknown
# Version: 2.6.32-23-generic 

Any comments on that? How could I get the same values on the method calls? Is there a difference related to the blocks on the OS image? 

Thanks...
