we have 8 nodes in an ES cluster and an index which we have set to 4 shards
with 1 replica. i would've assumed that this would mean 4 roughly equal
chunks on 4 nodes and replicas of those 4 chunks on the other 4 nodes but
that doesn't seem to be the case. for example, one node is primary for one
chunk and is a non-primary replica of two others and some nodes have no
data at all. is the rebalancer disabled by default? how can i check the
status? is there a way to manually redistribute the data?
thanks for any guidance!
