Subject Replication error in SOLR-6.5.1
Date Wed, 26 Sep 2018 05:20:38 GMT
Hi all,

I use SOLR-6.5.1. Before couple weeks I started to use replication feature
in cloud mode without override default behavior of ReplicationHandler.

After deployment replication feature to production, almost every day I hit
these errors:
SolrException: Unable to download <file name> completely. Downloaded x!=y
OR
SolrException: Unable to download <file name> completely. (Downloaded x of y
bytes) No space left on device
OR
Error deleting file: <file name>
NoSuchFileException: /opt/solr/<core name>/data/index.<datetime>/<file name>

All these errors I get when replica in recovering mode, sometimes after
physical machine failing or sometimes after simple solr restarting. Today I
have only one solution for it: after 5th unsuccess replica recovering, I
remove replica and add replica anew.

In all my solr servers I have 40% free space, hard/soft commit is 5 minutes.


What's wrong here and what can be done to correct these errors?
Due to free space or commitReserveDuration parameter or something else?
