推荐答案

索引似乎在索引过程中被锁定了.
通常索引中会有一个 write.lock 文件，需要将其删除才能恢复.
如果索引在两者之间中断或其他可能导致锁定文件仍在索引中的问题，则可能会发生这种情况.

It seems the index has been locked during indexing.
Usually there would be a write.lock file within the index which needs to be removed to get it back.
The conditions can occur if the indexing breaks in between or other issues which may cause to lock file to be still in the index.

检查 论坛

写锁是因为IndexWriter总是打开的在 Solr 中，甚至在奴隶上.

The write lock is due to the fact that an IndexWriter is always open in Solr even on the slaves.

检查索引锁定选项，这些选项可以处理配置中的条件.

Check for the Index Lock options which can handle the condition within configuration.
