Operations News
- Kashyap's Elasticsearch query script has been rolled out to CASTOR headnodes. Users are encouraged to test it and report any bugs.
- Samneet's query tool is under development and we hope to have an alpha version available for use by the end of next week.
- Plan to ensure PreProd represents production in terms of hardware generation are underway.
- The remaining 2014 disk servers have been deployed into production.
Operations Problems
- The problems with the draining tool have been understood and a fix is being change-controlled on Monday
- A new service class called 'cedaRetrieve' has been created to allow CEDA users (aka Kevin) to manually stage files for retrieval.
- The rebalancer has been tested and found to cause problematically large transfermanager queues even with low thresholds set. We will not be using it further until we have a fix.
Blocking Issues
- Neither rebalacing nor draining currently work.
Planned, Scheduled and Cancelled Interventions
- A Tier 1 Database cleanup is planned so as to eliminate a number of excess tables and other entities left over from previous CASTOR versions. This will be change-controlled in the near future.
