     19Nothing new, only the existing issues on which Tigran and Paul have no progress to report.

     21== BNL == 
     22 
     23Iris reported that she has just set up a testbed running 1.9.0-25 to exercise the convert from PNFS to Chimera. 
     24 
     25Initial results with some very small data were encouraging. 
     26 
     27She hopes to have the conversion completed by the end of the week. 
     28 
     29Once the dCache instance is running Chimera, what next?  Update directly to the latest dCache. 
     30 
     31Tigran said to check whether the pools use BerkleyDB or file for storing metadata.  The BerkeleyDB option will require some schema migration, which may require some tools that are not present in the latest versions of dCache. 
     32 
     33Perhaps the safest bet is to jump from golden release to the next golden release.

     35=== ATLAS === 
     36 
     37Iris is also trying to understand tape area space token: the accounting didn't seem to make sense. 
     38 
     39Tigran advised to investigate whether pinned files could be contributing to the unexpected usage.
