Oxford Gridpp Site becomes an NGS Affiliate

Not to be out done by Scotgrid, I should also point out that Oxford became an NGS affiliate at the same meeting (Dec 6th). See https://www.ngs.ac.uk/guide/affiliates/oxford-gridpp/

Oxford have added support for vo.southgrid.ac.uk, gridpp and supernemo.vo.eu-egee.org

Birmingham HV Network Upgrade

High Voltage Network Upgrade, over this weekend, means several systems will be off over the weekend.
It is hoped to keep the core service nodes up and running, but the number of worker nodes will be limited.

ALICE VO Box was not accessable to the users for a day, no problems were found by Yves.
Now reported as OK.

SouthGrid Update

Had some problems with LHCb users
Upgraded WN's to SL4
Disk failed on the se raid 5 disk array.
Upgraded the SL3 cluster to update 37. Some problems with the se, the DPM pool nodes had not had the latest lcg-vomscerts rpm applied. Secondly the site-info.def file on some of the nodes had an old entry for the ops vo which meant the gridmap file was not being created correctly.
This was changed to include:

VO_OPS_VOMSES="'ops lcg-voms.cern.ch 15009 /DC=ch/DC=cern/OU=computers/CN=lcg-voms.cern.ch ops'
'ops voms.cern.ch 15009 /DC=ch/DC=cern/OU=computers/CN=voms.cern.ch ops'"

The addition of voms.cern.ch being the important bit, (lcg-voms.cern.ch) was the old entry.

The BDII failed on Monday 3rd. A reboot fixed this.

So now that Oxford is uptodate we can go ahead and add support for some new VOs,
SouthGrid, gridpp and supernemo.

Random rm failures at Oxford

Random SAM test failures for rm, and later complaints from ATLAS were traced to one of the DPM pool nodes not having had the latest VOMS certs applied.
