nebula 2.0.0-rc1 storage重启失败问题

用户问答 使用问题
#1

提问参考模版：

  • nebula 版本：nebula 2.0rc1
  • 部署方式（分布式 / 单机 / Docker / DBaaS）：docker swarm
  • 硬件信息
    • hdd
      docker swarm重启后一直起不来，每隔几分钟就会重启，
      storage 日志如下，Do custom minor compaction!后进程就会stopping，不知道为啥。。。

把配置贴一下？

这是storage的配置

rocksdb_block_cache 改小一些试试

#5

内存不够。容器配置多少

#7

docker info 的数据是这么多250.8GiB
容器内存没有配置其他参数

#8

我理解这里我只有一个storaged，11个rocksdb实例，rocksdb不是查缓存吗，这个不是多个rocksdb共享的吗

#10

好的，我试下，后面会换到ssd

#11

我改成rocksdb_block_cache=2048，然后storage占用内存一直往上涨到30G+，再就又挂掉重启了，我记得我没重启之前内存占用有60G+

很抱歉，更正一下我上文中的错误回答，上文中提到的rocksdb_block_cache是在同一个进程中的多个kvEngine是共享的，单位是MB。
这个配置改小之后，内存打到30GB+后就又挂掉了，看log信息在07:01:50的时候收到了kill的Signal。目前系统的ulimit -n是多少？

#13

有core文件吗？可否查看一下堆栈信息？

#14

partition bloomfilter 那个参数改成true

#15

配置了还是一样

#16

docker swarm部署要怎么取到core日志

#17

ulimit -n 是102400

#18

20480改成100

#19

还是一样，内存增长到10G+，然后就收到终止信号重启

#20

你容器开的内存是多少？

#21

如图，是没有限制容器内存的，这里没显示是因为我服务停掉了

#22

每次重启增长到的内存数量都不太一样？昨天留言是30GB+，今天是10GB+？

Signal 15(Terminated) received, stopping this server 这个信号哪里发过来的？ 你把完整的INFO日志也贴一下呢？

你要是不带数据测试一下能正常启动吗？你说要换SSD测试，换了吗？

你的物理机呢，启动时候有注意过内存资源占用情况不。 你swarm 要启动多少个storaged呢？3个？每个都要那么多资源？
