     19No questions until we get through everyone :) 
     20 
     21Karsten: LDAP plugin documentation, Tickets, smaller reviews 
     22Tigran: Helped Leonie with her work. We can now use ownCloud sync clients natively with dCache 
     23        Investigated SSD pool issues. 
     24        Helped DESY admins with dCache components running out of memory 
     25        Did performance tests with Gerd's serialization update. 
     26Al:     Reviewing Developers Meeting discussion on ReplicaManager 
     27Christian: Updated WebPage, Resolving Tickets,  
     28           EMI/EGI things: EMI-3 will continue to be supported and will notify people 6 Month in advance if support will be dropped in the future. 
     29Dimitry: Migrated to 2.2 and chimera in the CMS Tier-1 Tape Backend System 
     30Gerd: Serialization of messages, speedup factor of 10, but no effect on dCache performance. Being in contact with Java devloper 
     31      Fixed XRootD compatibiliy with client, this could be due to IPv6/IPv4 conversion issues. This should be backported. 
     32       
     33= Plans for patch-releases = 
     34 
     35Should we make a new patch release?

     40= Trunk activity = 
     41 
     42Progress with new features... 
     43 
     44Al: 
     45- Gerd and Al started talking about how the MigrationManager and ReplcaManager should work together. 
     46- Should promoting of copies be the responsiblility of MigrationModule 
     47- Started sending file attributes along with the messages 
     48 
     49= Issues from [FIXME: Add link to yesterday's Tier-1 meeting] = 
     50 
     51Ulf, Xavier, Mark. 
     52 
     53Mark upgraded to 2.6 from 2.2 
     54KIT has a long downtime and a couple of issues 
     55  - problem with security limits, RPM should come with  
     56  - HotFile replication: dCache would prefer to do replication even though the file already exists on an unloaded pool. Not really sure about this. 
     57    Apparently PoolManager only saw one copy. 
     58      - Tigran: Maybe we see a similar behavior at DESY... 
     59
