Re: segment.gen file is not replicated
I have now updated to solr 3.3 but segment.gen is still not replicated. Any idea why, is it a bug or a feature? Should I write a jira issue for it? Regards Bernd Am 29.07.2011 14:10, schrieb Bernd Fehling: Dear list, is there a deeper logic behind why the segment.gen file is not replicated with solr 3.2? Is it obsolete because I have a single segment? Regards, Bernd
Re: segment.gen file is not replicated
This file is actually optional; its there for redundancy in case the filesystem is not reliable when listing a directory. Ie, normally, we list the directory to find the latest segments_N file; but if this is wrong (eg the file system might have stale a cache) then we fallback to reading the segments.gen file. For example this is sometimes needed for NFS. Likely replication is just skipping it?

While being smart I deleted it on slave from index dir and then replicated, but segment.gen was not replicated. Due to your explanation NFS could not be reliable any more. So my idea either a bug or a feature and the experts will know :-) Regards Bernd Mike McCandless http://blog.mikemccandless.com On Thu, Aug 4, 2011 at 3:38 AM, Bernd Fehling bernd.fehl...@uni-bielefeld.de wrote: I have now updated to solr 3.3 but segment.gen is still not replicated.

Re: segment.gen file is not replicated
I think we should fix replication to copy it?
