* RAL is closed after Friday afternoon 22nd December and will re-open on Tuesday morning 2nd January. Plans for the holiday period follow the pattern established over recent years and we will try and respond to urgent service-affecting events. The Tier1 on-call team will be in place throughout the holiday and will respond to alerts as usual. They will also carry out some additional checks throughout this period. The Machine Room and network operations teams will also be providing on-call cover during the holiday. However, please note that support will be limited on Christmas Day, Boxing Day and New Year’s Day.

'''Castor:'''
 
−
On Wednesday (6th Dec) all the SRMs systems (except LHCb – which had already been done) were successfully upgraded to the latest version (2.1.16-18)
 
−
Three disk servers (old ones from 2012) have been added to the LHCb Disk-only space in Castor to alleviate problems of this area being too full.
 
−
 
 
'''Echo:'''
 
'''Echo:'''
−
The maximum number of gridftp connections to each Echo gateways has been increased to 200 (from 100).
+
•            Background scrubbing has been going on. This has flushed out more bad disks – causing some callouts through the week.
−
Echo is running normally. Background scrubbing is going on. This is flushing out bad disks – and the rate at which it finds these is expected to drop over the next week or two. The plan is to run like this through the holiday period.
+
−
 
+
−
'''Services:'''
+
−
EGI will withdraw support for the WMS from the start of 2018. Our WMS service will be stopped on this timescale.
+
−
 
+
−
Network:
+
−
There was a problem of high packet loss for traffic to/from the Tier that passed through the RAL core network (and firewall) on Monday (4th). The problem started at midnight and was fixed around 15:30.
+
−
 
+
−
'''Infrastructure:'''
+
−
Following the failure of the generator to start during the power outage of a couple of weeks ago a faulty emergency power-off switch was found and has been replaced. Plans are being made for a generator load test – hopefully on Wednesday (13th Dec).
+
  
−
'''Certificates:'''  
+
'''Network:'''
−
Following problems with the updated UK CA certificate in the IGTF 1.88 rollout we had updated and then rolled back. This had left is with some issues in our configuration/deployment system (Quattor/Aquilon) – but those were resolved quickly. We made a plan to roll forward again tomorrow (12th Dec) – and that is still the plan.
+
•            Emergency card replacement at Harwell PoP on Thursday morning. This was announced to us and caused a short break in two out of the three OPN links (as expected)  
  
−
'''Christmas Plans:'''
 
−
We will follow the same pattern as in previous years. The on-call team will be in place as usual. Some additional checks will be made by those on-call. RAL is closed after Friday afternoon 22nd December and will re-open on Tuesday 2nd January.

RAL Tier1 Operations Report for 13th December 2017

Plans for the Christmas and New Year Holidays
Example alt text
Merry Xmas!
  • RAL is closed after Friday afternoon 22nd December and will re-open on Tuesday morning 2nd January. Plans for the holiday period follow the pattern established over recent years and we will try and respond to urgent service-affecting events. The Tier1 on-call team will be in place throughout the holiday and will respond to alerts as usual. They will also carry out some additional checks throughout this period. The Machine Room and network operations teams will also be providing on-call cover during the holiday. However, please note that support will be limited on Christmas Day, Boxing Day and New Year’s Day.
Review of Issues during the week 13th to 20th December 2017.

Echo: • Background scrubbing has been going on. This has flushed out more bad disks – causing some callouts through the week.

Network: • Emergency card replacement at Harwell PoP on Thursday morning. This was announced to us and caused a short break in two out of the three OPN links (as expected)


Current operational status and issues
  • None
Resolved Castor Disk Server Issues
  • GDSS743 (AtlasDataDisk - D1T0) is back in production.
  • GDSS705 (AtlasTape - D0T1) is back in production.


Ongoing Castor Disk Server Issues
  • None
Limits on concurrent batch system jobs.
  • CMS Multicore 550
Notable Changes made since the last meeting.

Infrastructure: • There was a successful generator load test last Wednesday (13th Dec).

Certificates: • The re-updating to pick up the updated UK CA certificate in the IGTF 1.88 rollout took place successfully last Tuesday (12th) as planned.

Castor: • Three Castor disk servers were moved from LHCb tape buffer to their disk-only (D1T0) storage.

Entries in GOC DB starting since the last report.

No downtime scheduled in the GOCDB between 2017-12-12 and 2017-12-20

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:

Listing by category:

  • Castor:
    • Update systems (initially tape servers) to use SL7 and configured by Quattor/Aquilon.
    • Move to generic Castor headnodes.
  • Echo:
    • Update to next CEPH version ("Luminous").
  • Networking
    • Extend the number of services on the production network with IPv6 dual stack. (Done for Perfsonar, FTS3, all squids and the CVMFS Stratum-1 servers).
  • Services
  • Internal
    • DNS servers will be rolled out within the Tier1 network.
