mongo-server 3.4.16
After upgrading from our mongo-ruby-driver fork (based on 2.4.2) to the official 2.8.0 release, we performed a failover and noticed a bunch of different types of exceptions.
Our topology was the following:
- oldprimary.example.com:27025 was the primary before the failover
- newprimary.example.com:27025 became the new primary
- baz.example.com:27025 was the arbiter before/after the failover
1. Mongo::Error::NoServerAvailable
Error:
No primary server is available in cluster: #<Cluster topology=ReplicaSetNoPrimary[oldprimary.example.com:27025,newprimary.example.com:27025,baz.example.com:27025,name=test,v=101734,e=5badef77446cd23001740b12] servers=[#<Server address=oldprimary.example.com:27025 UNKNOWN>,#<Server address=newprimary.example.com:27025 SECONDARY replica_set=test>,#<Server address=baz.example.com:27025 UNKNOWN>]> with timeout=30, LT=0.015.
