"How can I find what's stored locally?" These pages list all of the datasets stored in Canada, by site, then give the number of files per dataset. Datasets are listed alphabetically, and can be searched with CTRL-F:
http://gridinfo.triumf.ca/CA/datasets_in_CA/find_Canadian_datasets.html
(This page is made by running >dq2-ls -s "SITENAME" daily, along with >dq2-get-number-files ). Also, these pages are combined into one, unsorted, unalphabetized list that might be more convenient to search:
