Operational Issues (Gateway Auth failures) | accidentally broke preprod workernodes - docker had cached old layers for the new image | ||
cms-aaa naming convention | cms-aaa is the only remaining personality to use proxy/ceph as the xrootd service names Separate naming convention would be more appropriate, to have main/supporting (not so urgent). CC created, but due to be reviewed December | ||
XRootD Managers De-VMWareification |
Option 2 preferred for efficiency, but Option 1 decided on Option 1 would be simpler to implement for a temporary fix, as the move would be reversed antares tpc nodes to be moved to an echo leafsw, to confirm ipv4 real estate with James | ||
Compilation and rollout status with XrdCeph and rocky 8: 5.7.x | Upstream merging in process. Branch now exists. Documention (particularly for the Buffered IO is needed). | ||

UKSRC Storage Architecture | For v0.1 Requirements: POSIX-like access be provided ‘next to’ the compute. POSIX area ‘should be’ an RSE, to enable the transfers, and lifecylce management. Dissadvantages: Other ideas: Manilla style shares / volumes for each DID / container requested ? | ||

Site reports
Lancaster: Gerard updated to the latest reef (18.2.4), it wasn’t a completely smooth process but we got there in the end. Also as discussed in storage on Wednesday, turning off mclock made ceph behave a lot better.
Manchester also noticed similar problems with mclock (3 objects/hour with mclock). changing settings didn’t seem to have an effect,
lots of scrubbing but not updating the scrub date (scrubbing a bit broken on reef)
Reporting bugs flagged upstream
Glasgow: targetting pacific for upgrade, waiting for Reef stability
RAL upgrade might go to Quincy
mid-upgrade (pacific mons + nautiluse osd) - osd maps are created very quickly, but can bloat mon stores
