Replication problem on windows

[Rafał Kuć <r....@solr.pl>]

Hello!

We have Solr running on Windows. Once in a while we see a problem with
replication failing. While slave server replicates the index, it throws
exception like the following:

SEVERE: Unable to copy index file from: D:\web\solr\collection\data\index.20111025100000\_3s.fdt
to: D:\web\solr\Collection\data\index\_3s.fdt java.io.FileNotFoundException:
D:\web\solr\collection\data\index.20111025100000\_3s.fdt (The system cannot find the file specified)

We've added <commitReserveDuration> to the master server
configuration, but it didn't change that situation, the error still
happens once in a while.

Did anyone encounter such error ?

I found another old mailing list entry by searching google for your 
error message without filename/path.

It looked like they solved it by adding/updating the following config 
line, found in solrconfig.xml in deletionPolicy, which is found in 
mainIndex.  Increasing that number will increase the on-disk size of the 
index on your master server.

<str name="maxCommitsToKeep">2</str>

The directory paths in their error messages look exactly like yours, 
down the the difference in case between the from and to strings, so I 
fear that I am pointing you at information that you already have.
