PPS Reports

* Two links on agenda. * CERN PPS upgrading its WMS, used for SAM tests in the PPS. * Pilot test of the WMS in the PPS completed, will go to production shortly.

* Question from Lev with respect to pool account support under new WMS. CMS require a single mapping of unix account.

Assigned to Due date Description State Closed Notify  
NicholasThackray, AntonioRetico 2008-06-06 Check with CMS VO Cards about WMS and Pool account support.

Update 28-May-08: CMS confirms that the use of pool accounts for SGM has proved to be not working in many cases. The main problem is that the acls on the files are set by users and, if different accounts are used, one software manager could act (e.g. uninstall) packages installed by another.

On the other hand this is not relevant for WMS, where the distinction of pools per VO is not needed.

The conclusion is that the recommended configuration of the accounts has indeed to be different between CEs and WMS, at least as far as CMS is concerned.
As far as I am concerned this action can be closed.

EGEE Items From ROC Reports

ROC France
New CERN CRLS caused some problems.

Assigned to Due date Description State Closed Notify  
SteveTraylen 2008-06-06 Check if CRL lifetimes are monitored anywhere?

*Update 2nd June*
From Romain: There is a SAM test called "CE-wn-sec-crl". General results are public, but detailed results are available only to the ROC security contacts + SAM team.

Follow up question for Romain. CE-wn-sec-crl monitors CRL status on the WNs them self.
What was being asked for was central monitoring of the CA's CRL URLs.... It would make
for an easy rrd plot.

*Update 9th June*
There is central monitoring of CRLs here http://nagios.eugridpma.org/.
Also I have requested that the WLCG Monitoring Group considers getting these
to sites via its alarm/nagios/messaging framework. BUG:37632.

*Update 11th June* Ask the CODS to look at the nagios alarms for CRLs twice
a week.

2008-06-26 edit
New UK CA root cert caused problems, a post mortem is being ran by the UK.

CMS Service

Please see agenda for CMS notes: http://indico.cern.ch/conferenceDisplay.py?confId=34793 There are items for each T1.

ATLAS Service

Some problems with SAM updating ATLAS tests from CVS. Needs some work and discussion with SAM developers to improve the situation.

ATLAS suggest the recalculating the Site availability for all the Tier1 (even if only half of them were affected) following the problem of the SAM critical update that had not worked for the ATLAS SAM ui. The tier1s site availability should be recalculated between the 20th and the 26th of May.

Assigned to Due date Description State Closed Notify  
MaiteBarroso 2008-06-06 Check with Gridview/SAM if the tier1 availability for 20th -> 26th May can be recalculated given the failure of the ATLAS sam UI from 20th to the 26th May. Assigned to Maite for now.

Update 2-Jun: Discussed in minutes --> closing

Have found they have files deleted from /tmp during a /tmp period.

Assigned to Due date Description State Closed Notify  
SteveTraylen, EgeeSiteRepsGroup 2008-06-06 Look into why LHCb's files in /tmp are being deleted.

The reason is that python's tarfile unpacks files with a --preserve-atime so the
files are old as far as tmpwatch is concerned. A way forward is being discussed.
