Dear all,
Next week we will upgrade our cluster to LCG-2.4.0. At this point in time we will also upgrade from RedHat 7.3 to Scientific Linux 3.0.4. This means that the upgrade will be a lot of work, and we have planned the whole week (April 25-29) for it.
During the upgrade we hope to keep downtimes as short as possible. To prevent loss of jobs we need to shutdown the queues on the CE however.
The upgrade will not involve the SE teras.sara.nl and the RLS mu5.matrix.sara.nl!
Because the data of these services is published on the CE which will go down, we have installed a separate BDII on the RLS server.
During the upgrade we may move the information about certain services to this BDII to prevent the loss of this information.
So now SARA has the following BDIIs with site information:
# SARA-LCG2
ldap://giis.matrix.sara.nl:2170/mds-vo-name=saralcg2,o=grid
# SARA-RLS
ldap://rls.matrix.sara.nl:2170/mds-vo-name=sararls,o=grid
Note, that in order to have this information available to you, the new BDII should be included in the top BDII you use. The "all sites" list currently has this BDII, so most sites should be OK.
I'm not sure about experiment specific BDIIs though. So it may be wise to check this if you need to access data stored at the teras SE.
Kind regards,
Fokke Dijkstra
