RAL Tier1 Operations Report for 8th November 2017
Review of Issues during the week 1st to 8th November 2017. |
- At last week's meeting we reported that CMS were switched over to using xrootd.echo.stfc.ac.uk meaning that CMS jobs used xrootd.echo.stfc.ac.uk as the primary means of accessing local data via xrootd. That change was reverted - but has since been re-applied. There was a further issue where long-lived CMS jobs needed to complete before the changes were picked up by all CMS batch jobs.
Current operational status and issues |
- There is a problem on the site firewall which is causing problems for some specific data flows. Discussions have been taking place with the vendor. This is having an effect on our data that flows through the firewall (such as to/from worker nodes).
- CASTOR CMS Stager down. Investigation implies CPU error on physical box – “E1442 CPU2 machine check error. Power cycle AC.”)
Resolved Disk Server Issues |
- None
Ongoing Disk Server Issues |
- None
Limits on concurrent batch system jobs. |
- CMS Multicore 550
Notable Changes made since the last meeting. |
- Re-distribution of data in Echo onto the 2015 capacity hardware is ongoing. This is expected to complete in a few weeks.
- CMS batch switched to use Echo as the primary means of accessing local data via xrootd. If data not found there it will fail over to Castor.
- The Echo Gateways have had a parameter change that means the GridFTP gateways make better use of memory. This will enable the number of connections to each gateway server to be increased.
- A start has been made on updating Castor tape servers to SL7.
Entries in GOC DB starting since the last report. |
- None
Declared in the GOC DB |
- None
Advanced warning for other interventions |
The following items are being discussed and are still to be formally scheduled and announced. |
Ongoing or Pending - but not yet formally announced:
- Re-distribute the data in Echo onto the 2015 capacity hardware. (Ongoing)
- Update the LHCb Castor SRMs so as to be able to configure timeouts.
Listing by category:
- Castor:
- Update systems (initially tape servers) to use SL7 and configured by Quattor/Aquilon.
- Move to generic Castor headnodes.
- Echo:
- Re-distribute the data in Echo onto the remaining 2015 capacity hardware.
- Update to next CEPH version ("Luminous").
- Networking
- Extend the number of services on the production network with IPv6 dual stack. (Done for Perfsonar, all squids and the CVMFS Stratum-1 servers).
- Services
- The Production and "Test" (Atlas) FTS3 services will be merged and will make use of a resilient distributed database.
