Alice gateway congfiguration
Updates for space reporting and the related activities: Noted that some ‘reasonable’ level of activity seen on the gateway.

Tokens testing | JW | dev-gw4 in WLCG compliance and CMS token testing frameworks: Still to follow up on WLCG test failures; for CMS, currently passing (expected) tests; but suspect the configuration is not quite correct - to follow up at XrootD workshop.  | |
Status of space reporting and tests on Alice dev gateway and setting up of a unified configuration. | XRD-21 - Getting issue details... STATUS unified tpc working installed an RPM with latest mods to disk space reporting on ceph-dev-gw2 and it is showing the expected stats. I've informed Costin and asked him to confirm it looks OK. | ||
