Hi, Berkeley DB should be searching DB_HOME for a DB_CONFIG file. In OrangeFS, DB_HOME is the MetadataStorageSpace (or StorageSpace value in older versions) plus a sub directory whose name is a hex value. An example of DB_HOME, assuming MetadataStorageSpace is set to /orangefs/meta, would be /orangefs/meta/783070ef. So, place your DB_CONFIG in that directory and you should be good.
One another note, I'm don't know what parameters you're interested in changing but some (cache size and type) can be configured through the OrangeFS configuration file. Good luck, Michael 2011/12/11 g_p g_p <[email protected]> > Hello, > > i'm using PVFS and i would like to make some modifications in the Berkeley > configuration file > of PVFS. > > I'm using db4.8.30 Berkeley db. > > All the metadata servers consist of a file named pvfs2-server > which is located under /usr/sbin/ directory. > > If we open that specific file "/usr/sbin/pvfs2-server" we see some > methods of berkeley database in it(with some flags set).
