您好,请问您在使用哪个版本的IoTDB?
from iotdb.
应该是做了错误的元数据操作,0.9.3 版本修复了这个启动问题,可以升级到 0.9.3

我正在使用的是0.9.3

另外,我不太明白我该如何调整内存配置,首先我使用一个存储组,这个存储组下有10几个子节点,每个节点TTL是30天,那么每个节点就有43200条记录,10个节点就是43万条顺序的记录,当我使用./memory-tool.sh calmem -sg 1 -ts 432000计算内存时,得到Memory for writing: 14GB,那么我需要如何修改itodb-env.sh以适应这个数据量级?

@qiaojialin 问题解决后请来这里反馈下原因和解决方法

路径最后一层存在特殊字符,比如 [/.s1],而且没用双引号括起来,启动时候跳过了这些错误的日志,没有影响服务器启动。
路径最后一层如果想有多个 . 和特殊字符,可以用双引号括起来,不过所有insert、select查询都需要把最后一层括起来,下面这种是可以的:
create timeseries root.host_item_test."vfs.fs.size[/,free]" with datatype=FLOAT, encoding=RLE, compression=SNAPPY
insert into root.host_item_test(timestamp,"vfs.fs.size[/,free]") values(1,1)
select "vfs.fs.size[/,free]" from root.host_item_test
from iotdb.
另外,./memory-tool.sh calmem -sg 1 -ts 432000,这个 -ts 指的是时间序列数量,432000是实际的数据点个数,不是一个维度的。几万时间序列的负载一般都不需要计算这个内存,系统内部会自动调整
