IndexReader.reopen on SSHFS mounted index eventually fails with read past EOF
-----------------------------------------------------------------------------
Key: LUCENE-2538
URL: https://issues.apache.org/jira/browse/LUCENE-2538
Project: Lucene - Java
Issue Type: Bug
Components: Search
Affects Versions: 2.9.3
Environment: Linux 2.6.31-302-rs #7 SMP x86_64
Ubuntu 9.10
Java(TM) SE Runtime Environment (build 1.6.0_20-b02)
Reporter: Max Lynch
Priority: Minor
I have an index that Solr manages (as the sole known writer). I have mounted
it over sshfs. Periodically calling IndexReader.reopen() on that index will
result in the following error:
[java] java.io.IOException: read past EOF

I've read in other similar bugs that this indicates a corrupt index. I have
had no problems with the index so far and solr seems be fine with it, so I'm
not sure if that's the case. I know mounting an index over sshfs is not
recommended, and I have since moved to solr replication, but I wanted to report
this in case someone else encounters it.
