Solr 不备份核心

Question

我正在尝试备份 Solr 核心（独立模式下的 Solr 8.1.1）。我根据 https://solr.apache.org/guide/8_1/index-replication.html#configuring-the-replicationhandler

添加了复制 requestHandler

当我运行 /solr/core/replication?command=backup it returns:

{
  "responseHeader":{
    "status":0,
    "QTime":1},
  "status":"OK"}

但是当运行ning /solr/core/replication?command=details it returns:

...
"backup":[
      "exception","/opt/solr-8.1.1/server/solr/core/data/restore.20200414231901420/_22sklw_Lucene50_0.tim"]}}

当我指定备份名称和位置（例如 /solr-backups/，归 solr 用户所有）时，它从不创建任何文件。

我在这里做错了什么？如何让 solr 创建备份？

编辑：这显示在日志文件中：

Answer 1

看起来这是对 8.0.0 中重新引入的早期 Solr 错误的回归。它显然已在 8.4.0 中修复

见https://issues.apache.org/jira/browse/SOLR-13872
