While this is true, there are 2 points: (a) unfortunately, this is largely due to LCG [mis]features: the jobs fail far too often, and VERY many exactly on the stage of copying and registering files; if LCG data management tools would have been more reliable, we wouldn't have had that much garbage; (b) imagine the "leftover" files are not garbage: they were produced by very valid LCG jobs, and may well could have been perfectly valid data (most actually are). LCG was capable of producing it, how come it is not capable of storing it? There's nothing wrong with a full SE - or there shouldn't be. > I think this is more of a problem of data and storage management.

Oh, we do, but who ever listens to what the _users_ are mumbling! You guys have more weight :-) > It's your data after all (on our > machines).

Well, with the existing software you can't quite enforce any kind of policy. Of course one could check the available disk space, but it's basically identical to attempting to write to the SE: the attempt will fail if there's no enough space, and the job will try to write to another location. In short, if I can fill the allocated space, I *WILL*. Law of the Jungle, true. Stop me. Make a dedicated partition for me. I can't follow the peculiarities of 80+ sites. Quite often I can't even trust what is published in infosys, as many attributes are modified manually - if ever. Oxana.
