Hi Guys,
We are running a 3 node cluster, and each node returns a different number
of documents when issued a direct HTTP "_count" call.
The cluster holds about 150K documents and the differences range from 30~50
documents, but are still troubling.
This shouldn't be a "split brain" problem, since we have set:
discovery.zen.minimum_master_nodes: 2
We also have a "client" node, but since client nodes are eligible to be
master, I understand that they shouldn't affect the master election process.
Any Ideas about why and how this is happening?
Thanks!

minimum_master_nodes still doesn't protect you from all possible failure
scenarios, see Jepsen: Elasticsearch
What version are you running?

Alright, we'll try upgrading. Thanks
Meanwhile, any advice on how to fix an inconsistency once it is found? Is
there an API to forcefully "sync" nodes, or at-least reindex from a
specific node?

If this is replicas only, you should be able to set replica count to 0 and
then after a while back to 2 again
If this is sharded, then no, you'll have to reindex from scratch.
