Item | Presenter | Notes | |||||||||
|---|---|---|---|---|---|---|---|---|---|---|---|
Operational Issues (Gateway Auth failures) | CHEP week had a couple of callouts (self-resolving). Some restarts performed this week. | ||||||||||
cms-aaa naming convention | cms-aaa is the only remaining personality to use proxy/ceph as the xrootd service names cms proxy cfg ->unified.cfg ceph-> tcp.cfg a separate Separate naming convention would be more appropriate - , to have main/supporting? (not so urgent). | ||||||||||
Compilation and rollout status with XrdCeph and rocky 8: 5.7.x | Done (related: discussion on the upstream merger of XrdCeph). | ||||||||||
HTCondor | Pelican - 'Wizard' like webUI for configuration Tokens - non WLCG tokens use different token profiles/protocols | ||||||||||
Shoveler | |||||||||||
Deletion studies through RDR | |||||||||||
Deletions |
| Can now use time bins to count total and/or slow deletions over an interval. Need to modify log file extraction code to cover unlink after removing xattr (missed before, but low incidence) Will apply slow deletion query to DC24 ‘busy times’ for specific or all VOs. Need to check queries and merge gateway log files. | |||||||||
WN changes | https://github.com/xrootd/xrootd/issues/2308 now in 5.7.1 (and patched 5.7.0). (To confirm that this was rolled out - and working ok) | ||||||||||
periodic hackaton? | group coding/testing for specific tasks | ||||||||||
Xrootd testing framework | testing VM to be set up and be used for preprod testing Rob C - working on kubernetes deployment component Unit tests for xrootd (added since 5.7.0) ctest -VV -C Release -DCDASH=1 -DCOVERAGE=1 -S test.cmake | ||||||||||
XrootD gateway specs | 100Gb NICs Adding NICs to current gateways? keeping networking simple preferred on adding 100G NICs to current gws - switches might get overloaded | ||||||||||
SKA Gateway box | |||||||||||
Future developments ideas planning work | |||||||||||
Tokens Status | To split this into Operational aspects and any development / long-term planning aspects. technical implementation to accept tokens is in place, issues seem to be due to VO use cases on scheduling and accounting accounting - it’s in the pipeline but not coming soon on APEL | ||||||||||
Checksums improvements | There is a github issue open to merge this upstream https://github.com/xrootd/xrootd/issues/2338 streaming checksums |

Lancaster: Our CHEP talk was well received. Having a rough time with CEPH the last couple of weeks requiring forcing a switch between the MDS servers. When things settle down and we don’t have CHEP write ups to do we’re whimsically thinking to take a peek at the xrootd-s3 stuff.
