Thank you for
Hi,
we still have the problem that SolR deletes index files on closing the
application if the index was changed in the meantime from the production
application (which has an embedded SolR-Server).
The problem also occurs if we use a local file system instead of a NFS.
I have changed the loglevel
Can I just clarify something. The title of this thread implies Solr is
losing data when it shuts down which would be really bad(!) The core isn't
deleting any data, it is performing a merge, so the data exists, just in
fewer larger segments instead of all the smaller segments you had before.
So
I know Solr used to have issues with indexes on NFS, there was a
segments.gen file specifically for issues around that, though that was
removed in 5.0. But you say this happens on local disks too, so that would
rule NFS out of it.
I still think you should look at ensuring your merge policy is
Hi,
If you look at the files at the ls-Output in my last post you will see that
SolR has deleted the
segments_f -file. Thus the index can no longer be loaded.
I also had other cases in which the data directory of SolR was empty after the
SolR shutdown.
And yes, it ist bad.
Best regards

thanks for your interest in our problem.
I currently start SolR on Linux via
solr-5.3.1/bin/solr start -f
because we are still in

Let me see if I understand correctly:
You have two Solr instances pointing at the _same_ NFS-mounted
directory. The lock type of "single" implies this. And you're totally
and absolutely sure that only _one_ Solr instance writes to that
directory _ever_, right? It's not even the case that
Hi,
we are using SolR for some years now and are currently switching from SolR 3.6
to 5.3.1.
SolR 5.3.1 deletes all index files when it shuts down and there were external
changes on the index-files
(in our case from a second SolR-server which produces the index).
Is this behaviour intentional?
