I have the mongodb running on a 500GB primary disk. As the base started to grow a lot, I put a 1TB slave disk and changed the data folder to it. I know that over time, this 1TB disc will also be little.
I would like to know if there is a possibility to put a third disk and make the mongo also use it to save data. That is, in my conception mongo would use disks 2 and 3 and divide the data load between them. My question to the connoisseurs is: does this exist? Is it possible?
I have already researched the concept of sharding, and I have already understood it. But in shardind, I would split the data between two machines, that is, between two instances of mongodb. It's an option I have to use in the latter case.
But before starting for sharding, I would still like to know if it is possible in the same instance to split the data between two different folders (which will be on different disks).
I appreciate any information about it.
