raw is sparse by default so I don't think it's that big of a deal. I'm not sure what the peak file system impact of bonnie is ( haven't looked at the disk using during the benchmark) ; but the files are temporary and are cleaned up after the run. After doing a bonnie test, my RHEL5.5 guest is only consuming 5.6G of real space: # qemu-img info /tmp/kvm_autotest_root/images/rhel55-64-30G.raw image: /tmp/kvm_autotest_root/images/rhel55-64-30G.raw file format: raw virtual size: 30G (32212254720 bytes) disk size: 5.6G > testing, it seems a better approach to tweak bonnie's parameters to not > take up all the space on the VM's disk.

I'll take a look, but I was hoping someone was more familiar with bonnie on the list might already know. -- Ryan Harper Software Engineer; Linux Technology Center IBM Corp., Austin, Tx [email protected] _______________________________________________ Autotest mailing list [email protected] http://test.kernel.org/cgi-bin/mailman/listinfo/autotest
