Ruben,
That is good news!
Do you use NFSv4? Would you mind sharing your NFS mount parameters and
any changes to you need to make to the default solrconfig.xml?
From Google'ing around, people seem to tweek two areas in the
solrconfig.xml: locking type and commit points. Its not clear if NFSv4
resolves the problem that the older NFS versions have with file locking...
http://lucene.apache.org/core/4_0_0-BETA/core/org/apache/lucene/index/IndexDeletionPolicy.html:
"One expected use case for this (and the reason why it was first
created) is to work around problems with an index directory accessed via
filesystems like NFS because NFS does not provide the "delete on last
close" semantics that Lucene's "point in time" search normally relies
on. By implementing a custom deletion policy, such as "a commit is only
removed once it has been stale for more than X minutes", you can give
your readers time to refresh to the new commit before |IndexWriter|
<http://lucene.apache.org/core/4_0_0-BETA/core/org/apache/lucene/index/IndexWriter.html>
removes the old commits. Note that doing so will increase the storage
requirements of the index. See LUCENE-710
<http://issues.apache.org/jira/browse/LUCENE-710> for details."

Rubén Pérez Vázquez commented on MH-8033:
-----------------------------------------
We've been having our solr index on NFS since we started developing and testing MH. Our
production servers have the solr index in its default location under the MH
"storage" folder, which is mounted in an NFS share. We have observed no
problems at all.
Need to mention that solr should not be on nfs, it should be on localhost
--------------------------------------------------------------------------
Key: MH-8033
URL: http://opencast.jira.com/browse/MH-8033
Project: Matterhorn Project
Issue Type: Task
Components: Architecture & Services
Affects Versions: 1.2
Reporter: Christopher Brooks
Assignee: Greg Logan
Fix For: 1.2.1
TODO #2: Need to mention that solr should not be on nfs, it should be
on localhost. each service has its own solr, so running them on
separate machines is great. to do this, do:
org.opencastproject.storage.dir=local
org.opencastproject.file.repo.path=shared1
org.opencastproject.workspace.rootdir=shared2
gdl: /opt/matterhorn/felix/work/opencast/files
128.233.104.0/255.255.255.0(rw,sync,no_subtree_check)
/opt/matterhorn/felix/work/opencast/workspace
128.233.104.0/255.255.255.0(rw,sync,no_subtree_check) Works for me :)
