Chris Bowditch commented on LUCENE-425:
---------------------------------------

We have been using Lucene 1.9.1 for the past 2 years and this issue occurs on a regular basis.
Always on Windows and more often on machines with slower hard disks, i.e. Laptops. A colleague
of my downloaded the source and patched it to retry the rename and delete operations several
times before giving up. I will prepare a patch against trunk shortly which will solve the
problem.

>                 URL: https://issues.apache.org/jira/browse/LUCENE-425
>             Project: Lucene - Java
>          Issue Type: Bug
>          Components: Index
>    Affects Versions: 1.4
>         Environment: Operating System: Windows XP
> Platform: PC

> AddDocument periodically fails with "Cannot rename segments.new to segments". 
> Sometimes it happens after 10,000 documents, sometimes after 200,000 documents.
> My index is placed on a FAT partition. My Lucene version is 1.4.3. I am using 
> a single IndexWriter object and doing all AddDocuments calls serially from a 
> single thread.
> I saw some discussion about this problem in the mailing lists, but looks like 
> the problem wasn't completely eliminated yet.
> My suggested solutions are as follows:
> - If renameTo() fails, wait some time and retry. After this, apply the other 
> methods that are now in FSDirectory.java. Retry them as well after waiting for 
> some time.
> - In the IndexWriter constructor, check for 'segments.new' if 'segments' 
> cannot be found. This would allow recovery if FSDirectory failed on a previous 
> run. Now I have to write the recovery code myself outside of Lucene.
