Couchbase Server Community Edition v3.0.1 ghost bucket

I have a cluster of 3 nodes (8 cores 32GB RAM) running Couchbase server community edition v3.0.1. One node suddenly failed over and when I try to rebalance, I get the following error message. But, one interesting fact is that there is no such bucket on the cluster right now! The “apRawLogBucket” in the error message was deleted some 6 months ago.

Current buckets list is as below:

Now the thing is rebalance doesnt work and I think I will need to create a new cluster from scratch. Any other options?
