While testing the master build with lucene 4.1, I got a permanent merge error filling up my logs. Has anyone else seen it? Anything I can provide to help debug?

hey, can you give some more background here, like did you start this on an old index ie. an index you created with a previous version of ES / Lucene? Can you reproduce this? simon On Monday, February 25, 2013 7:54:46 AM UTC+1, Taras Shkvarchuk wrote: > While testing the master build with lucene 4.1, I got a permanent merge > error filling up my logs. > Has anyone else seen it?

Not sure what type of info you're looking for, so you can e-mail me for more details, I can probably even provide the index in question for debugging. There are 420K root level documents as all of which have small nested documents. Re-indexing nearly the same data resulted in an index without corruption.

I have had to remove the single shard and replaced it with an empty version to be able to recover. One important thing to add: after the exception happened the cluster started to behave bad: - node A tried to send the failed shard to node B - while recovering on B the recovering failed with this exception - B was somehow renaming the broken files - A tried to send the failed shard again to node B - while recovering it failed again... - B renamed the files again... .... ... this didn't stop until the disk was full on node B.

hey simon! good to meet you again, long time no see! Is there any chance we can get a hold on this corrupted shard? It would be awesome to get this and reproduce the problem somehow. You can contact me on [simon.willnauer@elasticsearch.com](mailto:simon.willnauer@elasticsearch.com) directly though!
