How to manage your disk space on the Grid

For me, these commands only work on lxplus.

SetupProject Dirac
lhcb-proxy-init
dirac-dms-storage-usage-summary /lhcb/user/<initial>/<username>

dirac-dms-user-lfns --help

will give you a detailed overview of all the options. Very useful are -m 3, which will show all files older than 3 months, and –Wildcard=“*.root”, which will only show root files.

Do

dirac-dms-data-size --Unit=MB myLFN

where myLFN can also be a list of LFNs.
