Hi peter,
Thank you very much for your quick reply.
I tried the CheckIndex method. It can't work on my crashed index.
In the error message, it says the segments file in the directory is missing.
and when I use the -fix param, new segments file still can't be write.
I even try the CheckIndex without the assertion, it still can't work.
Do you know why this is happening ? Does it mean that the segment file can't
be rewrite at all?
Btw, i am using the nightly build solr.
following is the error messages:
[r...@localhost lib]# java -cp lucene-core-2.9-dev.jar
org.apache.lucene.index.CheckIndex -fix /solr/example/data/index/
NOTE: testing will be more thorough if you run java with
'-ea:org.apache.lucene...', so assertions are enabled
