I just have this issue in production. @maganap's (Mar 15) comment saved my bacon!

Using mongodb 3.2.10, no need to dump the oplog, just do this on the first member:

use local
db.system.replset.remove({}) 

Then restart the member. It'll now still have it's oplog, and it's data. Just run:

rs.initiate()
rs.reconfig(conf)

Where conf is the new conf. Then on each of the other members, just run the trashing of the replset data above and restart them. When they start they'll join the set.
