From IGE (needed to be aligned with the versions in EPEL reposistory):

2. Operational Issues

2.1 Site configuration in GOCDB

Some sites were not showing in the Top-BDII GLUE2.0 branch, even if the Site-BDII is GLUE2 enabled. It was a site configuration issue in GOCDB, please find more information here

2.2 LDAP dependencies in BDII

As reported in the Operations Meeting on October 24th the Site-BDII is still installed with openldap-servers v.2.3, this is true for both EMI and gLite3.2 versions of the software. Site admins need to manually upgrade the openldap RPMs to openldap2.4-servers.

Note: the dependency to openldap 2.4 will be added in the next release of the Site-BDII, for EMI-2.

2.3 Sites "candidate" or "suspended"

As discussed in the May 2011 OMB, the sites in suspended or candidate status for too long should be closed. We still have a large number of sites in this situation, you can find the lists of sites in those statuses from the Performance page.

As requested in this GGUS ticket, all sites to which on 01 January 2012 the following conditions apply, will be closed by COD:

If there are technical reason to extend the deadline for specific sites, NGI are kindly requested to open a GGUS ticket to COD - explaining those reasons and providing a timeline for the site reintegration - before December 31st 2011.

2.4 Slurm support for BLAH

SLURM has been recently discussed in the LCG_ROLLOUT list as an open source alternative to Torque/Maui which has been reported to suffer of scalability problems when used in big clusters.

A survey across the Resource Centres in the past months reported that (about 170 answers):

Those numbers were reported to EMI, but did not giustify a strong requirement for SLURM.

Recently also Ibergrid (PIC) and NGI_UK(David Wallom reply to this RT ticket) expressed interest in SLURM, for its scalability performance.

If we want to push the SLURM support for CREAM/BLAH (and the other related components) for EMI-3 we need to assess in the next month and a half how many sites are considering alternatives to Torque/Maui.

A way to do that would be a very short survey:
