1) Is it bad to put BDB RewriteMaps on an NFS server? Is anyone else doing it without problems? 2) Is it true that some versions of BerkeleyDB don't have "read-only" semantics, and could this be causing the problem? 3) Is the problem here related to incorrect POSIX file-locking semantics on the NFS server as some of my colleagues at work have implied? This NFS server hardware is fairly recent (purchased within the last 3 years) so I'd be very surprised if this were the case. 4) Could it be possible that this is just tickling a bug in the Linux kernel? We're running SuSE Linux Enterprise Server 9.
I'm not at all an expert in this, but my understanding is that using berkeley DB over NFS -- even for read-only access -- is asking for trouble. Oracle has this to say about it: http://www.oracle.com/technology/documentation/berkeley-db/db/ref/env/remote.html which seems to suggest that read-only access is possible. But I'd think all bets are off if you change the database, even from the local machine.
