loki报错与解决方法：failed to initialize table

笔者今天发现使用的loki报错了，启动报错退出，上网查询，没找到雷同的问题，所以只能自己查找原因解决。具体报错原因如下：

仔细看上述该内容，其中第八行显示的是：

level=error ts=2023-02-16T00:20:42.974109059Z caller=index_set.go:104 table-name=netflow_19397 msg="failed to initialize table netflow_19397, cleaning it up" err=timeout

尤其是最后 cleaning it up 既然failed了，那么是否可以人工手动删除呢？

因此笔者直接手动删除该文件，然后再重新启动loki，居然可以了。

汗，具体原因为什么会产生这种问题，还需仔细查找。
