Lancaster: CEPH - seems fairly happy at the moment, Gerard investigating some issues with scrubbing. XRootD - having a set of LSST functional tests fail with permission denied whilst making their directories. The xroot logs are worse then useless for debugging auth issues. There shouldn’t be any access issues, and access works for me and Tim. However it reminded me of issues Glasgow had with LHCB (mkdir over http getting permission denied). Any tips for teasing out more information on xroot auth decisions?
Jyothish - LHCB functional tests needed additional entries in the authdb to stat root folders. e.g. lhcb:user rl additional to lhcb:user/ a
Similarly is there any good way of logging deletions server side?
Logging needs improvement across xrootd - one event one line, machine parsable, reduce clutter, uniform format. possibly bring up in the workshop? Gerard embarked and a grand adventure in CEPH upgrades this week, first to the top of Pacific, then to Reef (all done whilst live). Nothing really important exploded, but the monitoring and dashboards have been finicky. In general smooth sailing though. In hindsight Gerard reckons he might well have skipped going to the top of Pacific first and just gone straight to Reef. On xroot, the LSST auth errors mentioned last week turned out to be on their side (they were using a defunct voms server to serve their proxies) - so not an xroot issue per se, but the fact that this impossible to debug from the xroot side is a huge niggle.
Glasgow: Sam build newer versions of xrootd on CC7 and 8. (anticipating 5.6.9), and awaiting any updates for LB.
