Performance storm-webdav e migrazione¶ 20m

https://ggus.eu/index.php?mode=ticket_info&ticket_id=150181

problemi visti da ATLAS risolti/capiti (differenza in bandwidth delle macchine coinvolte)

solved (StoRM) We (or I) now finally understand StoRM behavior and in the latest test we reached * webdav time to transfer 2TB (2000x 1GB) with 200 concurrent connections ... 1403s (1.42GB/s) * SRM+gsiftp time to transfer 2TB (2000x 1GB) with 200 concurrent connections ... 217s (9.22GB/s) The reason for different throughput is not related to StoRM, but WebDAV interface total capacity to the backend storage is now 4GB/s (perfectly OK for current ATLAS TPC transfers to INFN-T1 disks with monthly average ~ 400MB/s) while for GridFTP total capacity is 30GB/s. This will change once we move everything to WebDAV and than GridFTP interfaces will be converted to the WebDAV. Petr

Deployment di una istanza Vault¶ 15m

ACL for local groups of the same VO¶ 15m

ACL for local groups of the same VO that wrote the file:

https://issues.infn.it/jira/projects/STOR/issues/STOR-1350

it seems that acl are set to allow the write operation (RW) and never changed also after the put done. It could be the wanted behaviour but we need to discuss how to address the requirements (i.e from JUNO) that asks to inhibit writing for local users
    should we use different groups, i.e. JUNO_local or can be managed via storm?
LHCb seems to expect the R only for the lhcb group after the write operation in /storage/gpfs_lhcb/lhcb/user:

            <aclMode>AoT</aclMode>
            <default-acl>
                <acl-entry>
                  <groupName>lhcb</groupName>
                  <permissions>R</permissions>
                </acl-entry>
            </default-acl>
