MAIN NEWS:

  • BDII_top:
    New version of BDII_top:
    - This is a minor update of the Top BDII which fixes a sporadic installation issue (see bug report). The parameter dncachesize has been included in file /etc/bdii/bdii-top-slapd.conf to address some memory issues. In addition a new version of glite-info-update-endpoints that provide a new configuration option certification_status, which has been requested by EGI.

    This patch provides an updated BLAH to address some problems when SGE is used as batch system in the CREAM CE
    Known issues
    See: http://grid.pd.infn.it/cream/field.php?n=Main.KnownIssues
    - It may take very long time for BNotifier to know about a job status change dependening on the size of the job registry and of the accounting file.
    - BupdateSGE dies when GE produces an accounting record with "start_time -/-" and "end_time -/-", it will be fixed in next patch
    - Details about bug fixes & feature

  • GLEXEC_WN :
    - New version of GLEXEC_WN:
    This update is needed to bring in new versions of the LCMAPS-plugins-pep-c and PEP-API.
    - The PEP-API needs updating to fix a randomly occuring time-out when gLExec tries to authorize and the Argus-PEPd-server.
    - The LCMAPS-plugin-c-pep needs updating in order to use the new PEP-API library. At the same time, the new plugin can now handle a situation when the X509_USER_PROXY (proxy of pilot job user) is located on an NFS partition with root-squash enabled.
    This update fixes an issue with the YAIM configuration tool for glite-GLEXEC_wn.
    See bug https://savannah.cern.ch/bugs/index.php?83779
    The issue mostly affects sites with a large user database and a large number of worker nodes, as the configuration script wrongfully does a full listing of all user accounts in search of the glexec account.
    - Details about bug fixes & features

  • LB :
    - New version of LB:
    This release of L&B 2.1.21 introduces several hotfixes, namely to job registration and event delivery initiated by WMS, and also fixes several bugs that were affecting the interlogger under non-standard conditions (disk full, long-term inactivity, etc.).
    - Details about bug fixes & features

  • SGE_utils :
    - New version of SGE utils:
    This gLite-SGE_utils release implements the proper BLAH configuration (in /opt/glite/etc/blah.config) to support SGE/BLAH changes delivered by CREAM CE 1.6.6 for gLite 3.2/sl5_x86_64. Other bug fixes are also included. The reconfiguration of the service is mandatory.

  • UI :
    New version of UI:
    - containing a variety of updated clients and removing the need for some known issue workarounds documented for the previous release.
    Known issues:
    - As with all glite-UI releases the correct way to update from a previous (RPM) based release is to use "yum groupupdate glite-UI".
    - If a "yum update" is done on a previous version of the node while the glite-UI repository is enabled a partial update of the UI will happen. To complete the update it becomes necessary to do: 
# yum -y remove glite-lb-client glite-service-discovery-api-c glite-wms-ui-configuration
# yum -y groupupdate glite-UI
- Details about bug fixes & features

Instructions

Checking/Updating YUM configuration

Repository settings

Please check the instructions you find at the following link:

IGI Repository settings for gLite 3.2

yum-autoupdate settings:

As good practice is suggested to disable the yum-autoupdate service. Any other settings is decided at site-manager own risk!

To disable the service it is available the following script "disable_yum.sh" (thanks Giuseppe Platania) that can be used to REALLY disable yum-autoupdate.

Actions

Each of the following sections reports the actions that may be follow in order to upgrade your profiles. Please execute ONLY the actions listed on the table above in the column "Actions" and in the row corresponding to your profile!

Metapackage update

Please see yum tips for additional information about YUM.

  • Update YUM metadata and install the new rpms. 

yum clean all
yum install

Please remember that on case of WN you should use the "groupinstall": 

yum groupinstall ig_WN_torque

On CE CREAM:

Before installing/updating a CREAM CE remember to install xml-commons-apis: 

 yum update xml-commons-apis

When installing/updating a CREAM CE node, a dependency problem such as:
Error: Missing Dependency: libcares.so.0()(64bit) is needed by package glite-security-gss-2.0.0-6.sl5.x86_64
could be seen. In this case, the update should be done doing: 

 yum update --exclude=c-ares
Please note that doing: 
 yum update ig-CREAM_torque
or 
 yum update ig-CREAM_LSF
you are not guaranteed to have all relevant RPMs updated.

When installing/updating ig_CREAM_torque (in general torque) remember to change the torque directory

On the Server (usually CREAM CE host) stop the pbs_server (Even if the gLite documentation says pbs_mon): 

/etc/init.d/pbs_server stop
mv /var/spool/pbs /var/torque
ln -s /var/torque /var/spool/pbs
/etc/init.d/pbs_server start

On VOBOX:

When installing/updating the VOBOX 3.2.11 it doesn't work out of the box. This is because there is a new version of glite-lbjp-common-gss that obsoletes package glite-security-gss, on which glite-VOBOX still depends. The recommended upgrade sequence is: 

rpm -e --nodeps glite-security-gss
yum update

On ig_WN_torque:

When installing/updating ig_WN_torque (in general torque) remember to change the torque directory doing: 

/etc/init.d/pbs_mon stop
mv /var/spool/pbs /var/torque
ln -s /var/torque /var/spool/pbs
/etc/init.d/pbs_mon start

Editing local configuration files

* In the last updates many variables have been changed or moved to ''services'' and ''defaults'' directories. Please carefully check your ''<site-info.def>'' and files under ''services/'' and ''nodes/'' directories comparing to the new ones distributed with latest released ''yaim'' modules. For example you can use ''vimdiff'' like here below: 

vimdiff /opt/glite/yaim/examples/siteinfo/ig-site-info.def

You may find more detailed information on configuration files structure here:

and on configuration variables here:

Nodetype reconfiguration

IMPORTANT: /services directory

Please ensure that you have all the NEEDED configuration files under your ''/services'' directory (for example: ''ig-se_dpm_mysql'', ''ig-se_dpm_disk'', ...).

For any details please refer to the reference "IGI YAIM configuration files”

  • Reconfigure the nodetype

IMPORTANT: /services directory

Please ensure that you have all the NEEDED configuration files under your ''/services'' directory (for example: ''ig-mpi'', ''ig-mpi-ce'', ''ig-mpi-wn'', ...).

Remember to add the variable TORQUE_VAR_DIR in services and change the BATCH_LOG_DIR in ig-site-info.def to /var/torque

Known Issues: tomcat5 start log4j error

in a yaim configuration even if it terminates successfully, an error is thrown and in the log you could find:
Starting tomcat5: /usr/bin/rebuild-jar-repository: error: Could not find log4j Java extension for this JVM /usr/bin/rebuild-jar-repository: error: Some detected jars were not found for this jvm it is not important for cream to work. 

/opt/glite/yaim/bin/ig_yaim -c -s <site-info.def> -n <nodetype>

Where '''' is one of the nodetypes listed in the "Nodetypes" column of the table above.

NOTE: Please remember to add ”-n ig_BDII_site” if you want to reconfiguring a site BDII on top of your CE

Middleware services restart

Look at your ''chkconfig'' services list and restart all middleware-related service: 

chkconfig --list | grep 3:on | sort

Then restart with: 

service <middleware-service> restart
