GridPP DPM toolkit 1.3.0 released

I meant to post about this last week, as I have released a new version of my DPM admin toolkit. This release includes a new tool called gridpp_dpm_dpns_du. This reports on the usage of directories in the DPNS namespace. This tool is something that CMS people at Bristol were asking for such that users could manage their own space.

$ gridpp_dpm_dpns_du -h
usage: gridpp_dpm_dpns_du /dpm/path/to/directory

-h, --help show this help message and exit
-s, --si Use powers of 1000, not 1024.
-xEXCLUDE, --exclude=EXCLUDE
Directory to ignore.

One thing that I have noticed is that the tool sometimes claims that a directory contains (say) 914354654K. However, when you dpns-ls -l the directory it does not contain any files or sub-dirs. Deeper investigation using dpns-ls --delete shows that DPM still has some remnant of an old file replica which was previously in that directory, but has now been marked as "D" for deleted. If there are no problems, these files can be removed with rfrm. Let me know if you find any other bugs.

Note that the rpm depends on DPM-interfaces > 1.6.11-4 due to the inclusion of the dpm-listspaces tool (which needs the latest API). You can find the latest rpm here.
