  • One collection over 60 submissions remains in "Waiting" status due to a LB problem (its nodes are in status "Submitted"); this are the wmproxy logs:

  • There is this warning in wmproxy submitting collections:
19 Jun, 14:58:32 -W- PID: 2746 - "wmpcoreoperations::submit": Unable to find SDJRequirements in configuration file

  • Fond a problem in the wmproxy. After some collections submissions it stops working and with the top command you can see that the glite-wms-proxy processes are using all the CPU (It seems that the problem is related with the porting to gsoap 2.7.10):
[Thu Jun 19 15:43:50 2008] [warn] FastCGI: (dynamic) server "/opt/glite/bin/glite_wms_wmproxy_server" (pid 7938) terminated due to uncaught signal '11' (Segmentation fault)

WM

  • After the recovery of a collection the "pending" nodes are forgotten.

  • BUG #27215: FIXED (see also #38359 FIXED)
    • If the sum of the dimensions of the first two files is exactly equal to the limit, the job stays in state RUNNING for ever and ever.

  • BUG #38509: The WM's recovery procedure hangs if no relevant events are found for a given request

  • BUG #38366: Recovery doesn't work with a list-match request. FIXED

JC/LM

ICE

LB

  • The status of the collection is not correctly computed
  • glite-lb-interlogd doesn't stop (you need a "kill -9")

Configuration

  • Add glite-wms-ice at the metapackage dependencies
  • Remove "rgma" fron the enviroment variable GLITE_SD_PLUGIN
  • Add "globus gridftp" at the gliteservices list (gLiteservices)
  • Remove from the metapackage these rpms:
    • checkpointing
    • partitioner
    • interactive (and thirdparty-bypass)
    • rgma-* (and service-discovery-rgma-c)
  • glite-lb-interlogd doesn't stop (you need a "kill -9")
  • Modify the cron purger file
# Execute the 'purger' command at every day except on Sunday with a frequency of six hours
3 */6 * * mon-sat glite . /opt/glite/etc/profile.d/grid-env.sh ; /opt/glite/sbin/glite-wms-purgeStorage.sh -l /var/log/glite/glite-wms-purgeStorage.log -p /var/glite/SandboxDir -t 604800 > /dev/null 2>&1

# Execute the 'purger' command on each Sunday (sun) forcing removal of dag nodes,
# orphan dag nodes without performing any status checking (threshold of 2 weeks).
0 1 * * sun glite . /opt/glite/etc/profile.d/grid-env.sh ; /opt/glite/sbin/glite-wms-purgeStorage.sh -l /var/log/glite/glite-wms-purgeStorage.log -p /var/glite/SandboxDir -o -s -n -t 1296000 > /dev/null 2>&1
  • Set the ICE configuration section
  • Remove IsmBlackList parameter
  • Set jobdir as the default for the DispatcherType parameter of wm
  • Add the parameter EnableRecovery = true; ti the wm configuration section
  • Add this cron to create the host proxy:
0 */6 * * * glite . /opt/glite/etc/profile.d/grid-env.sh ; /opt/glite/sbin/glite-wms-create-proxy.sh /var/glite/wms.proxy /var/log/glite/create_proxy.log

Other

  • On script glite-wms-purgeStorage.sh the command glite-wms-create-proxy.sh has to be called with its path:
[glite@devel19 ~]$ /opt/glite/sbin/glite-wms-purgeStorage.sh -l /var/log/glite/glite-wms-purgeStorage.log -p /var/glite/SandboxDir -t 302400
Certificate will expire
/opt/glite/sbin/glite-wms-purgeStorage.sh: line 27: glite-wms-create-proxy.sh: command not found

  • Probably on /opt/glite/sbin/glite-wms-create-proxy.sh it is better to use the --force option for command mv, instead the move commands should be blocked here:
[glite@devel19 ~]$ mv /var/glite/wms.proxy.14913 /var/glite/wms.proxy
mv: overwrite `/var/glite/wms.proxy', overriding mode 0400?
