背景： 我用fuel9.0部署了openstack，并且安装了最新的trove，能正常使用。但使用官方的diskimage-builder创建ubuntu-mysql镜像的时候总是会报错，显示如下： dib-run-parts Tue Oct 4 12:57:08 UTC 2016 99-tidy-logs completed dib-run-parts Tue Oct 4 12:57:08 UTC 2016 ----------------------- PROFILING ----------------------- dib-run-parts Tue Oct 4 12:57:08 UTC 2016 dib-run-parts Tue Oct 4 12:57:08 UTC 2016 Target: cleanup.d dib-run-parts Tue Oct 4 12:57:08 UTC 2016 dib-run-parts Tue Oct 4 12:57:08 UTC 2016 Script Seconds dib-run-parts Tue Oct 4 12:57:08 UTC 2016 --------------------------------------- ---------- dib-run-parts Tue Oct 4 12:57:08 UTC 2016 dib-run-parts Tue Oct 4 12:57:08 UTC 2016 01-ccache 0.016 dib-run-parts Tue Oct 4 12:57:08 UTC 2016 01-copy-manifests-dir 0.084 dib-run-parts Tue Oct 4 12:57:08 UTC 2016 40-unblock-daemons 0.030 dib-run-parts Tue Oct 4 12:57:08 UTC 2016 50-remove-img-build-proxy 0.011 dib-run-parts Tue Oct 4 12:57:08 UTC 2016 51-bootloader 0.033 dib-run-parts Tue Oct 4 12:57:08 UTC 2016 60-untrim-dpkg 0.075 dib-run-parts Tue Oct 4 12:57:08 UTC 2016 99-tidy-logs 0.235 dib-run-parts Tue Oct 4 12:57:08 UTC 2016 dib-run-parts Tue Oct 4 12:57:08 UTC 2016 --------------------- END PROFILING --------------------- rm: cannot remove '/tmp/dib_build.tBIihUi4': Device or resource busy 而且，我在程序中断后，试图自己sudo rm -rf /sudo rmdir都没有用。
