If your getting java.io.FileNotFoundException:
/mnt/nfstest/repository/lucene/lucene-icm-test-1-0/segments_h75 within 2
minutes, this is very odd indeed. That would seem to imply your deletion
policy is not working.
You might try just using one of the nodes as the writer. In Michaels
comments, he always seems to mention the pattern of one writer many
readers on nfs. In this case you could use no LockFactory and perhaps
gain a little speed there.

Hi Mark
Yes, thank you. I can see your point and I think we might have to pay
some attention to this issue.
But, we sometimes see this error on an NFS share within 2 minutes of
starting the test so I don't think this is the only problem.
Once again, thanks for the idea. I will certainly be looking to
modify the code in the LuceneIndexAccessor to take this into account.

This is an interesting choice. Perhaps you have modified
LuceneIndexAccessor, but it seems to me (without knowing much about your
setup) that you would have odd reader behavior. On a 3 node system,
if you
add docs with node 1 and 2 but not 3 and your doing searches against
all 3
nodes, node 3 will have old readers opened until you add a doc to
node 3.
This is an odd consistency issue (node 1 and 2 have current views
because
you are adding docs to them, but node 3 will be stale until it gets a
doc),
but also if you keep adding docs to node 1 and 2, or just plain add
no docs
to node 3, won't node 3's reader's index files be pulled out from
under it
after 10 minutes? Node 3 (or 1 and 2 for that matter) will not give
up its
cached readers *until* you add a doc with that particular node.
Perhaps I am all wet on this (I havn't used NFS with Lucene), but I
think
you may need to somehow coordinate the delete policy with the
LuceneIndexAccessor on each node.
This may be unrelated to your problem,and perhaps you get around the
issue
somehow, but just to throw it out there...
