DPM admin tools

I have started to put together a set of scripts for performing common (and possibly not-so-common) administration tasks with DPM. This uses the python interface provided by the DPM-interfaces package. It's definitely a work in progress, but you can you can checkout the latest set of scripts from here (assuming you have a CERN account):

isscvs.cern.ch:/local/reps/lhcbedinburgh/User/gcowan/storage/dpm/admin-tools

If not, then I have put them in a tarball here.

They are very much a work in progress, so things will be changing over the next few weeks (i.e., keep a lookout for changes). As always, contributions are welcome. I should probably package this stuff up as an rpm, but haven't got round to that yet. I should also put them into the sys-admin repository and write some documentation (other than the -h option). Like I say, contributions are always welcome...

dCache admin scripts

Last week I finally got a chance to have another look at some of the dCache administration scripts that are in the sysadmin wiki [1]. There is a jython interface to the dCache admin interface, but I find it difficult to use. As an alternative, the guys at IN2P3 have written a python module that creates a dCache admin door object which you can then use in your own python scripts to talk to the dCache [2]. One thing that I did was use the rc cleaner script [3] to clean up all of the requests (there were 100's!) that were stuck in Suspended state. You can see how the load on the machine running postgres dropped after removing the entries. Highly recommended.

I also wrote a little script to get information from the LoginBroker in order to print out how many doors are active in the dCache. This is essential information for sites that have many doors (i.e. Manchester) but find the dCache 2288 webpage difficult to use. I'll put it in the SVN repository soon.
