* Problems with "CMSDisk" in Castor reported last week have been resolved. CMS deleted files freeing up space and three more disk servers were added to the service class. (Although one of the later has subsequently failed and is currently out of service).
+
* There are some ongoing grumbly problems with the WMSs. The developers have been contacted.
* There was a problem on Thurdsay with the batch farm caused by a particular (biomed) user running very large jobs. This led to problems for other VOs. The jobs were killed and the user banned on the CEs. This problem recurred over the weekend as the original banning was not placed in Quattor. The user was more again banned over the weekend. A ticket about this from LHCb was raised to an 'alarm' status. This was responded to but the alert didn't page out correctly.
+
* A problem has been uncovered while investigating a missing Atlas file. Some half dozen files were lost during the draining of a disk server at the end of February. We are working to check if this is the only such instance of this and (with the developers) to understand the problem. Investigations so far suggest this is not a widespread problem. Draining of disk servers has been stopped while this investigation takes place.  
* There was a problem between 13:40 and 13:55 yesterday (6th May) when Argus stopped mapping DNs to users and job submissioned failed.
+
* Around ten days ago a GGUS ticket was escalated to an 'alarm' ticket by LHCb but the Tier1 pager failed to call out. This has been traced to a a problem with the e-mail from GGUS. The GGUS team were contacted. They have fixed the problem and we have tested that the alarm tickets now work again.

* GDSS758 (CMSDisk - D1T0) failed on Friday morning (2nd May). This was a a new server thta had only gone into production the previous day. Following initial investigations the server was returned to service later that day. Since then the server has been drained and is undergoing further tests.

RAL Tier1 Operations Report for 14th May 2014

Review of Issues during the week 7th to 14th May 2014.
  • There are some ongoing grumbly problems with the WMSs. The developers have been contacted.
  • A problem has been uncovered while investigating a missing Atlas file. Some half dozen files were lost during the draining of a disk server at the end of February. We are working to check if this is the only such instance of this and (with the developers) to understand the problem. Investigations so far suggest this is not a widespread problem. Draining of disk servers has been stopped while this investigation takes place.
  • Around ten days ago a GGUS ticket was escalated to an 'alarm' ticket by LHCb but the Tier1 pager failed to call out. This has been traced to a a problem with the e-mail from GGUS. The GGUS team were contacted. They have fixed the problem and we have tested that the alarm tickets now work again.
Resolved Disk Server Issues
  • None.
Current operational status and issues
  • Nothing to report.
Ongoing Disk Server Issues
  • None
Notable Changes made this last week.
  • Testing CVMFS Client version 2.1.19 ongoing. This is now rolled out to one batch of worker nodes. So far so good.
  • pheno & enmr.eu added to list of authorized VOs on ARC CEs
  • FTS3 updated to version 3.2.22 this morning.

Advanced warning for other interventions
The following items are being discussed and are still to be formally scheduled and announced.
  • Provisional dates for the Castor 2.1.14 upgrade delayed to: Nameserver: Tuesday 10th June; Stagers to follow.
  • We are starting to plan the termination of the FTS2 service now that almost all use is on FTS3.

Listing by category:

  • Databases:
    • Switch LFC/FTS/3D to new Database Infrastructure.
  • Castor:
    • Castor 2.1.14 testing was largely complete, although a new minor version (2.1.14-12) will be released soon.
  • Networking:
    • Move switches connecting recent disk servers batches ('11, '12) onto the Tier1 mesh network.
    • Make routing changes to allow the removal of the UKLight Router.
  • Fabric
    • We are phasing out the use of the software server used by the small VOs.
    • Firmware updates on remaining EMC disk arrays (Castor, FTS/LFC)
    • There will be circuit testing of the remaining (i.e. non-UPS) circuits in the machine room during 2014.
Entries in GOC DB starting between the 7th and 14th May 2014.
