Running any sort of database on a network-mounted filesystem is a Bad
Idea. Databases need to grab and release locks - possibly hundreds or
thousands per second - and this is very inefficient across a network.
In some implementations of NFS it does not work reliably at all.

You should use the SLURPD replication system to keep slave copies in
sync.

I have summaried this in a new FAQ entry:

	http://www.openldap.org/faq/index.cgi?file=766

What do you want to achieve with those slave servers? There are very
few things where NFS-mounted database files would actually help even
if they worked.
