No questions until we get through everyone :)

Karsten: Smallfiles for DPHep and Docukenmtnation

Christian: Tickets!, pcells -> testing, Patches

Al: Decoupled Alarms from other sercvice

Dmitry: Metawork

Gerd: Helping KIT upgrade

Tigran: Debugging NFS problems with CMS instance

= Special topics =

== KIT upgrade ==
Gerd: 
   Successfully upgraded, Spacemanager problems, because of stuff (e.g., indices) in tables
   Duplicated records, null values - no idea why.
   Currently restoring 2.6 dump
   Made a patch to solve those issues for other sites
   
   Issue with duplicated records remaining.

== CMS NFS ==
Tigran:
   50% of worker nodes use NFS4.1 now
   From last thursday, maybe caused by network problems, problems started to occur,
   pool were online but not serving data, patch committed, other patches running but 
   not yet in repo.
   More problems with network caused new problems -> NFS4.1 offline
   -> will setup another NFS door for other use cases so users and worker nodes don't interfere. 
   -> split reads and writes and metadata operations

   -> open question: why are we falling back to proxy IO

Dmitry: 
   - we have a case of one direcotry where ls takes some seconds and ls -l takes about 2h.
   - Also GridFTP transfers looks to kill performance and push up IO wait
