The mongomirror project is leveraging code from the mongo-tools project, but requires a few minor changes in order to work.
The changes are:
- exporting a few fields from the mongodump/mongorestore structs
- adding a new flag (not user-visible) that allows bypassing all user/role functionality in those tools
I've made a pull request here: https://github.com/mongodb/mongo-tools/pull/77.
Please let me know if there's anything I can do to help with this effort.
