[galaxy-dev] hierarchical ObjectStore - noatime

Hi, we want to put some more hard drives into your Galaxy Server. And we plan to use the hierarchical ObjectStore for that purpose. The new discs will be type="distributed" id="primary" and the old disc will become type="disk" id="secondary". If I understood correctly the old disc is them in some read-only state and will not touched until the primary discs are full or not working ... Is it save to mount the old discs or all discs with noatime, to get a small performance gain? Is Galaxy using noatime? Thanks, Bjoern
