Problems with query errors caused by MongoDB index file corruption

Problem Description:

When MongoDB shuts down abnormally, it can cause the index file to be corrupted, causing the data not to be reflected on the index when it is updated.

Solution:

Use the script to rebuild the index of all the tables in MongoDB.

var names = Db.getcollectionnames (); for (var i in names) {var name = Names[i];        print (name);    var coll = db.getcollection (name); Coll.reindex ();}
