SL4 usage survey

This is to collate information about the usage of SL4. This is a EGI initiative, to determine the current usage of SL4, and barriers to use of more recent software.

LondonGrid

UKI-LT2-BRUNEL

I have the following services on glite 3.1

-> CEs dgc-grid-40, and dgc-grid-44

Soon to be replace by CreamCEs

-> CE dgc-grid-35

it should be decommissioned by the end of the year

-> BDII

to be upgraded in the next few months

-> SE dgc-grid-50

it has only 2% of the data at the site. I'm planning an upgrade for the 3rd week of December. Most of the data at Brunel is in dc2-grid-64, glite 3.2 SE.

UKI-LT2-IC-HEP

I have a SL4 WMS (wms02.grid.hep.ph.ic.ac.uk) as there is no SL5 WMS in glite. I use wms01 to test the EMI WMS, but it took today's (9/8/11) update to get it working. I intend to keep the glite 3.2 WMS around for a while longer until the EMI version is stable. Note that our lcg-CEs are running SL5 (technically CentOS 5).

UKI-LT2-QMUL

lcg-CE: and having problems with CREAM, so will remain until that's done.

UKI-LT2-RHUL

lcg-CE:- have to plan for this by finding a suitable hardware.

UKI-LT2-UCL-CENTRAL

UKI-LT2-UCL-HEP

NorthGrid

UKI-NORTHGRID-LANCS-HEP

lcg-CE: and having problems with CREAM, so will remain until that's done.

UKI-NORTHGRID-LIV-HEP

UKI-NORTHGRID-MAN-HEP

UKI-NORTHGRID-SHEF-HEP

glite 3.1 ce which we want to retire this month/early Seprember

ScotGrid

UKI-SCOTGRID-DURHAM

UKI-SCOTGRID-ECDF

UKI-SCOTGRID-GLASGOW

  • DPM MySQL head node. Upgrade planned.
  • Some DPM pool nodes - rolling update to SL5.
  • WMS & L&B servers. Will remain until there is a supported combination of L&B and WMS that will run on the same host.
  • VOMS server (already under threat of upgrade due to incident) - upgrade planned.
  • SL4 VOBOX for PANDA. In discussion with the VO on that one.

No problems anticipated in update to SL5, once software requirements are handled.

SouthGrid

UKI-SOUTHGRID-BHAM-HEP

we are running our two LCG-CEs (epgr02 & epgr04) on glite 3.1 and SL4. Our CREAM CEs seem OK though so if the consensus is to retire them, I'm happy to! (Not scheduled, but (effectively) planned)

UKI-SOUTHGRID-BRIS-HEP

  • lcg-CE (lcgce04.phy.bris.ac.uk ) planning to upgrade to cream-ce very soon.
  • StoRM v1.3 SE (lcgse02.phy.bris.ac.uk) is still SL4 as is its slave gridftp server gridftp01.phy.bris.ac.uk. StoRM v1.4 & 1.5 are not supported on SL5, and StoRM v1.6 & 1.7 (supported on SL5) are very unstable & not production ready yet (just ask Chris Walker who's had ++painful experience with them). Waiting on stable StoRM for SL5 - soon hopefuly.
  • lcgnetmon (owned+operated by RAL) is still SL4 AFAIK

UKI-SOUTHGRID-CAM-HEP

We have following nodes running SL4

  • lcgCE 3.1 (condor)
  • SE (DPM)
  • 7 x disk-servers

Upgrading SE and the disk-serves currently under progress. the lcgCE would stay longer I imagine.

EFDA-JET

All nodes running SL5

UKI-SOUTHGRID-OX-HEP

  • SL4 DPM head nodes still in use
  • Some DPM pool nodes , although we are in the process of draining an migrating to SL5 based nodes.
  • All old LCG-ce's have been decommissioned.
  • On the UK Nagios monitoring we use an SL4 based my proxy server as it is not yet available on SL5

UKI-SOUTHGRID-RALPP

2 lcg-CE's, one upgrade scheduled thie week, the other in the next few weeks.
