Query errors caused by corrupted MongoDB index files

Query errors caused by corrupted MongoDB index files

Problem description:

When MongoDB is disabled abnormally, the index file may be damaged, and the data is not reflected in the index when the data is updated.

Solution:

Use scripts to recreate indexes of all MongoDB tables.

Var names = db. getCollectionNames ();

For (var I in names ){

Var name = names [I];

Print (name );

Var coll = db. getCollection (name );

Coll. reIndex ();

}
