The SAM CE tests include the replication of a file from the site's default SE for "ops" to a central SE, for which a DPM node at CERN is the default choice and thereby almost always used. This node still runs SLC3, which is no longer supported and must be upgraded. Testing on SLC4 with the latest DPM version for gLite 3.1 shows that if the switch were made today, approximately 10% of Production sites would fail the CE tests due to old versions of GFAL and lcg-utils running on their Worker Nodes! Sites in Italy and UKI are particularly affected.
For example, RAL has versions of lcg-utils that are over a year old. In the meantime, there have been 18 updates, including 3 marked high priority!
Therefore, this is a call to all sites that are failing the CE tests in the SAM Validation instance to upgrade their WNs to the latest version ASAP. We would like to migrate the SAM DPM production instance in ~3 weeks from now (by Monday 10th of August).
So, please, all ROCs, follow this up with your sites - if need be, by opening GGUS tickets.
Thanks in advance and best regards,
There are at least these 45 problematic CEs spread over 36 sites (ordered by ROC):
