There is a bug that leaves old index.* directories in the Solr data directory.
Here is a script that will clean it up. I wanted to make sure this is okay, without doing a core reload. Thanks. #!/bin/bash DIR="/mnt/servers/solr/data" LIST=`ls $DIR` INDEX=`cat $DIR/index.properties | grep index\= | awk 'BEGIN { FS = "=" } ; { print $2 }'` echo $INDEX for file in $LIST do if [ $INDEX == $file -o $file == "index" -o $file == "index.properties" -o $file == "replication.properties" -o $file == "spellchecker" ] then echo "skip: $file" else echo "rm -rf $DIR/$file" rm -rf $DIR/$file fi done
