We are using (read only mounted) "FileStorage"s on NFS systems heavily. Of course, we expect that they are considerably slower that those on a native file system. Read/write mounted storages may get locking problems (as locking over NFS requires some infrastructure). -- Dieter

Keeping the Data.fs on a NFS is not a good idea - there will be at least issues with performance. Keep it local. -aj

You may want to investigate GlusterFS instead. From our experiments, it works just fine for read/write. Locking is fine too. Would be advisable to setup ZEO instead. Note that GlusterFS is still under heavy development, thus may not be suitable for production any time soon. ;) KwangErn

Under development, no practical experiences available -> nothing that a serious Zope user would use in production -aj
