在ElasticSearch v1.1.0中插入新文档后，有时会出现noshardavailableactionexception错误。 使用
进行检查时curl 'localhost:9200/_cat/shards/cvk'
我得到了答案：cvk 0 p UNASSIGNED
使用命令重新启动弹性：
/etc/init.d/elasticsearch restart
一切正常。
ES在VPS ubuntu v12上运行，索引只有1个分片并且禁用了复制。
我发现＆＃34;设备上没有空间＆＃34;我的日志中的错误。但我的机器上有足够的光盘空间。我上传了一批1000份文件（每份文件大约512字节）。
如何解决冲洗问题？如果不可能，如何通过REST接口重新分配分片（不重启服务器）？

首先，您似乎正在运行Elasticsearch，并在根分区上创建索引：
Filesystem Size Used Avail Use% Mounted on
/dev/vda 20G 13G 6.6G 65% /
udev 237M 12K 237M 1% /dev
tmpfs 50M 216K 49M 1% /run
none 5.0M 0 5.0M 0% /run/lock
none 246M 0 246M 0% /run/shm
如果你有能力安装另一个驱动器，通常不是最好的主意。
您在Lucene索引段合并期间失败，这通常需要大量可用空间。由于只有20G的非常小的分区，磁盘空间使用率已达到65％，因此您可以轻松地耗尽空间，特别是因为您同时竞争所有其他进程的磁盘需求。有关管理和配置Elasticsearch合并策略的更多详细信息：

您可能无法在20GB分区（也是根分区）上可靠地索引和管理9 GB的数据，尤其是在您大量更改数据时。您可以尝试将其设置为避免/减少可能有助于磁盘空间的段合并，但这仍然可能无效。
关于它为什么占用尽可能多的空间，这取决于您如何映射数据，但一般来说Elasticsearch默认存储所有数据的副本，其中包含所有数据的原始形式，以及所有数据每个字段的索引数。
如果您确实需要适应20GB系统，我会仔细查看您的映射，看看哪些字段不能索引或不存储 -

问题确实存在于光盘领域。由于未知原因，ES占用所有可用磁盘空间。 这里发生了什么：
我通过索引中的批量API添加了大约75000个文档（全部成功）。
然后根本不要触摸ES。并监控磁盘空间。
在5分钟内，所有空间都被/ var / lib / elasticsearch / elasticsearch / nodes / 0 / indeces / cvk / 0 / index /中的少量文件占用 最大的空间文件_3ya.fdt（3gig） 在丢失碎片之前，有一些名为_3ya_es090_0的文件，扩展名为.tim .pos .doc，每个大约400mb。 丢失碎片之后，所有这些文件都消失了。
所以显而易见的解决方案是添加光盘内存。
但是新问题：
为什么ES需要x10磁盘空间而不是正在添加的数据大小？
有没有办法知道何时停止在现有分片中添加新文档？
如果我们创建多个分片而不是一个分片会有帮助吗？
如何从当前服务器获取最大值的任何其他建议？服务器有20GB的空间。我们只需要为小型研究索引大约9gig的数据。
