Review of action items (tasks)

Status of the subtasks of TASK:7981 : "Set-up and run Cream CE Pilot (Phase2)" (see them in the PPS tracker )

Notes:

TASK:7139 : Install a Cream CE at CNAF-PPS - In progress - 28d - 90% - last update: 15/7


TASK:7157 : Verify behaviour of CreamCE in nagios - In progress - 7d - 10% - last update: 21/11

Antonio:

EGEE/CERN/INFN-PADOVA-CREAMTEST has been created in the GOCDB

for this site all the nagios/SAm test are supposed to work, because it publishes in a simil-configuration way

the other site BDIIs will be published by CERN_PPS (or other PPS sites). This will likely cause some alarms in Nagios

The actual situation of how CREAM nodes are published in PPS is .


  1. Two site BDIIs are hard-coded in PPS TOP BDII (They should be not visible in SAM)
    • INFN-BARI-CREAMTEST ldap://cream-ce-1.ba.infn.it:2170/mds-vo-name=INFN-BARI-CREAMTEST,o=grid
    • INFN-CNAF-CREAM ldap://cert-07.cnaf.infn.it:2170/mds-vo-name=INFN-CNAF-CREAM,o=grid
  2. One site BDII corresponds to the site INFN-PADOVA-CREAMTEST site in GOCDB
    • INFN-PADOVA-CREAMTEST ldap://cream-27.pd.infn.it:2170/mds-vo-name=INFN-PADOVA-CREAMTEST,o=grid
  3. One site BDII is now published in turn by the CERN_PPS site BDII *INFN-PADOVA-CREAMTEST-PBS ldap://cream-34.pd.infn.it:2170/mds-vo-name=INFN-PADOVA-CREAMTEST-PBS,o=grid

The third option (nested site BDIIs) is the less painful from the pilot operations perspective, so I would like to understand if the Nagios monitoring detects particular problems with it. If not I'd rather configure all the pilot resources in this way (attached to one existing PPS site). As this configuration does not reflect the production one if it turns out to be unusable in Nagios (e.g. too many errors reported in the published information) we will move to the approach #2

It is confirmed that now cream CEs belonging to the pilot have been imported in SAM

TASK:7427 : Configure FCR in PPS to handle CREAM-CE - 0% - last update: -

Antonio: We didn't start because it depends on SAM working well


TASK:7986 : Install a Cream CE at FZK-PPS - In progress - 0% - 28 d - last update: 8/10

Angela: We had issues installing the service, and we couldn't find the time to report them to Massimo.

Antonio invites to report the issues as soon as possible to the developers, because one of the goals of the pilot is to have installation issues sorted out.

Status and results of the pilot service (by VOs and sites)

CMS:


Alice:

Nothing to report

Status and results of the development (by developers)

Antonio asked news on BUG:44454 (InputSandbox files modified on creamCE (bad symbols added)

Open Issues (by VOs, sites, deployment teams)

Recommendations for release and deployment

none

Decision about termination/extension of the pilot

The decision is made to extend the pilot of one month (conventional end date set to 16th of December)

The next check point meeting will be on the 25th of November. For that date the new tag of Cream is expected to have been released and deployed in the pilot

AOB

Due date of "service" tasks (run service XX at YY) will be set to 1 day after the check-point date (in order for them not to get to expiration)
