 Description   

Hi,
My replica set configuration have now a local database of 94GB and I don't know what should I do and which could be the reason for that problem.

I need space, what can I do?

Regards
Daniel

You can close the Issue. I cannot find the "Resolve button"

Thx!

The local database is always excluded from the backup service, so won't cost anything.

That's the reason why I have 1.111h available in the Replica Chart on MMS service, isn`t it??

Oplog is stored into local "database". Do you recommend me to exclude it from Backup service??

Large oplog is useful when secondaries may go offline for periods of time. The bigger it is, the longer secondary can stay offline and receive incremental update afterwards. I leave it up to you to calculate more appropriate size for your case.

I have the default options and my disk in 2TB, that's the reason (I guess).

How can I change that size?? What size do you recommend me??

Regards and thanks
Daniel

What's the size of your oplog (defaults to 5% of disk size, IIRC)? Maybe make it smaller?
