     21Al: Moved office, posted RemplicaManager patches, and Alarms, setting up VMs for Debug session, worked on document for Replica Manager

     24Paul: Tier1 meetings, focused on 2.9 release

     27 
     28= Plans for patch-releases = 
     29 
     30Should we make a new patch release? 
     31 
     32Our test system recently failed because of a sha-2 certificate (S2/G2) -> Therefore upgraded it to use EPEL versions, but then some clients failed when using dCache.org CA issued certificates. 
     33Because of that, upgraded the release machines to use "proper" certificates, but that needed the S2 tests to be rebuild which gave other errors. 
     34The cause apparently is a bug inside the S2 libraries.  
     35-> fixed the S2 tests.  
     36Until this is fixed for everything, we cannot do more releases. 
     37 
     38= Trunk activity = 
     39 
     40Progress with new features... 
     41 
     42== HTTP 3rd party transfers == 
     43 
     44What is the status of the 3rd party HTTP transfer feature? 
     45- We have a working client that is using apache commons client. This is in test, but currently stalled because of the S2 problems. 
     46 
     47Is it integrated with the transfer manager? 
     48- Yes 
     49 
     50= Issues from [FIXME: Add link to yesterday's Tier-1 meeting] = 
     51 
     52We had a lot of people connecting. 
     53 
     54Thursday: Simon mentioned they have Webdav in production for selected people.  
     55-> will backport filehopping fix 
     56 
     57Tuesday: 
     58Some more people connected (e.g., NDGF) 
     59KIT reports "dcache dump heap" does not work anymore, and apparently the statistics does not scale too well with a lot of files. 
     60-> We would need a way to calculate the statistics with any number of files. 
     61-> We could use Quartz to have the pools to create a file with a report. For this the Universal Spring cell could implement some API that can then be used to periodically generate a report. 
     62This might also be worth to use in other places in dCache as we currently have many differnt approaches 
     63 
     64Marc: The Admin Service (ssh2) stops listening after some time. 
     65  This is caused by missing file descriptors, because they are not released. 
     66 
     67Ivan: IN2P3 asked for help on the NFS+Kerberos issue. 
     68   
     69NFS+enstore seems to work now, we can merge.
