[03:20:30] <RyansWorld> Hello everyone I running a website on AWS Lightsail. Does anyone know how to start mongoDB and keep it running?

[04:21:48] <wlxmhls> hello! can I set mongodb checkpoint interval? I want to specify the period time of disk sync for mongodb. Thanks!

[05:05:47] <wlxmhls> is there anybody

[05:10:05] <wlxmhls> 艹，怎么没人回答我的问题啊

[05:51:48] <wlxmhls> 我自己找到了

[05:52:01] <wlxmhls> I found it by myself.

[09:00:08] <sgfgdf> hello, guys! i have documents with property representing a date in the form of string like so -- "2016-01-15". now i need to aggregate over these documents using for example the "$month" operator. the problem is that they work with a date type. i tried the "$dateFromString" operator, but it turns out that my mongo version is 3.2.11 and this operator was introduced in version 3.6. is there any way i can

[09:00:13] <sgfgdf> still convert my string as a date type and use the aggregation operators?

[10:39:06] <jackdt> hello! I've got a collection of documents having YEAR and MONTH as integers. I'd like to filter for example (Y >= 2017 and M >= 12) AND (Y <= 2018 and M <= 6), meaning 2017/12 <= document <= 2018/06.... do you have any idea on how to achieve this on Mongo 3.4? Thanks :)

[13:12:05] <poigru> Hi guys, we have a mongodb which doesn't want to startup again.

[13:12:24] <poigru> The error message is: 2018-06-11T13:09:02.769+0000 E STORAGE [initandlisten] WiredTiger (0) [1528722542:769785][13:0x7f4e6914be00], file:WiredTiger.wt, connection: read checksum error for 4096B block at offset 12288: block header checksum of 2896414579 doesn't match expected checksum of 3327239497

[13:13:08] <poigru> We already tried many google links, especially those recommending "mongod --repair" and "wt salvage"

[13:13:17] <poigru> But unfortunatly nothing helps!

[13:13:48] <poigru> Can someone help us to get the collection data out of the dbpath to recover it?

[13:18:56] <poigru> Does anybody has an idea how to repair the file WiredTiger.wt?

[13:32:41] <poigru> Anybody also ever got a read checksum error on startup?
