<p><b>New page</b></p><div>== SL4 usage survey ==<br />
<br />
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.<br />
<br />
== LondonGrid ==<br />
=== UKI-LT2-BRUNEL ===<br />
<br />
I have the following services on glite 3.1<br />
<br />
-> CEs dgc-grid-40, and dgc-grid-44<br />
<br />
Soon to be replace by CreamCEs<br />
<br />
-> CE dgc-grid-35<br />
<br />
it should be decommissioned by the end of the year<br />
<br />
-> BDII<br />
<br />
to be upgraded in the next few months<br />
<br />
-> SE dgc-grid-50<br />
<br />
it has only 2% of the data at the site. I'm planning an upgrade for the <br />
3rd week of December. Most of the data at Brunel is in dc2-grid-64, <br />
glite 3.2 SE.<br />
<br />
=== UKI-LT2-IC-HEP ===<br />
<br />
I have a SL4 WMS (wms02.grid.hep.ph.ic.ac.uk) as there is no SL5 WMS in glite.<br />
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.<br />
Note that our lcg-CEs are running SL5 (technically CentOS 5).<br />
<br />
=== UKI-LT2-QMUL ===<br />
<br />
lcg-CE: and having problems with CREAM, so will remain until that's done.<br />
<br />
=== UKI-LT2-RHUL ===<br />
lcg-CE:- have to plan for this by finding a suitable hardware.<br />
<br />
=== UKI-LT2-UCL-CENTRAL === <br />
=== UKI-LT2-UCL-HEP ===<br />
<br />
== NorthGrid==<br />
=== UKI-NORTHGRID-LANCS-HEP ===<br />
<br />
<br />
lcg-CE: and having problems with CREAM, so will remain until that's done.<br />
<br />
=== UKI-NORTHGRID-LIV-HEP === <br />
=== UKI-NORTHGRID-MAN-HEP === <br />
=== UKI-NORTHGRID-SHEF-HEP ===<br />
<br />
glite 3.1 ce which we want to retire this month/early Seprember<br />
<br />
== ScotGrid==<br />
=== UKI-SCOTGRID-DURHAM === <br />
=== UKI-SCOTGRID-ECDF === <br />
=== UKI-SCOTGRID-GLASGOW ===<br />
<br />
*DPM MySQL head node. Upgrade planned.<br />
*Some DPM pool nodes - rolling update to SL5.<br />
*WMS & L&B servers. Will remain until there is a supported combination of L&B and WMS that will run on the same host.<br />
*VOMS server (already under threat of upgrade due to incident) - upgrade planned.<br />
*SL4 VOBOX for PANDA. In discussion with the VO on that one.<br />
<br />
No problems anticipated in update to SL5, once software requirements are handled.<br />
<br />
== SouthGrid==<br />
=== UKI-SOUTHGRID-BHAM-HEP ===<br />
<br />
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!<br />
(Not scheduled, but (effectively) planned)<br />
<br />
=== UKI-SOUTHGRID-BRIS-HEP ===<br />
* lcg-CE (lcgce04.phy.bris.ac.uk ) planning to upgrade to cream-ce very soon.<br />
<br />
* 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.<br />
<br />
* lcgnetmon (owned+operated by RAL) is still SL4 AFAIK<br />
<br />
=== UKI-SOUTHGRID-CAM-HEP ===<br />
We have following nodes running SL4<br />
* lcgCE 3.1 (condor)<br />
* SE (DPM)<br />
* 7 x disk-servers <br />
<br />
Upgrading SE and the disk-serves currently under progress. the lcgCE would stay longer I imagine.<br />
<br />
=== EFDA-JET ===<br />
All nodes running SL5<br />
<br />
=== UKI-SOUTHGRID-OX-HEP ===<br />
*SL4 DPM head nodes still in use<br />
*Some DPM pool nodes , although we are in the process of draining an migrating to SL5 based nodes.<br />
*All old LCG-ce's have been decommissioned.<br />
* On the UK Nagios monitoring we use an SL4 based my proxy server as it is not yet available on SL5<br />
<br />
=== UKI-SOUTHGRID-RALPP ===<br />
<br />
2 lcg-CE's, one upgrade scheduled thie week, the other in the next few weeks.<br />
