错误概述 #
简要来说，当 Elasticsearch 尝试读取由主节点写入数据存储的文件时遇到问题，就会出现此错误。这可能是由于以下原因导致的：
- 网络问题
- 磁盘空间不足
- 文件损坏
解决方案 #
要解决此问题，可以尝试以下方法：
- 检查并确保有足够的磁盘空间
- 验证节点之间的网络连接
- 检查文件损坏情况，必要时从备份恢复
- 重启 Elasticsearch 服务
日志上下文 #
日志 “a file written by master to the store [” 的类名是 BlobStoreRepository.java。我们从 Elasticsearch 源代码中提取了以下内容，供那些寻求深入上下文的开发者参考：
if (seedRead.equals(seed) == false) {
throw new RepositoryVerificationException(metadata.name(), "Seed read from master.dat was [" + seedRead +
"] but expected seed [" + seed + "]");
}
} catch (NoSuchFileException e) {
throw new RepositoryVerificationException(metadata.name(), "a file written by master to the store [" + blobStore() +
"] cannot be accessed on the node [" + localNode + "]. " +
"This might indicate that the store [" + blobStore() + "] is not shared between this node and the master node or " +
"that permissions on the store don't allow reading files written by the master node", e);
} catch (Exception e) {
throw new RepositoryVerificationException(metadata.name(), "Failed to verify repository", e);
