We've hit the following scenario:

   - X is the primary
   - Y is a secondary but is struggling to keep up with the oplog and is
   starting to have noticable replication lag
   - Z is also a secondary and has syncingTo in rs.status() set to Y... as
   a result Z is dropping behind too even though it is actually healthy

Is there a way to force Z to sync to X?

Thanks,
Colin

Colin,

Yes, have seen this exact problem before.

You can hack on your /etc/hosts file to redirect the secondary to read from anyone you want.  So just put a false entry in there for the server it's reading from pointing back to the primary.  I think there are tickets to deal with this in the future.

Hi Colin,
There is a JIRA ticket for this request: https://jira.mongodb.org/browse/SERVER-3921.
The issue has been resolved and will be available in MongoDB version
2.2, the next stable release.
