Hello eveybody ! In a 6.8 cluster of 3 hot nodes and 2 cold nodes (with node attribute "Zone" and forced awareness option) : hot_node1: Zone1 hot_node2: Zone1 cold_node_4: Zone1 / hot_node3: Zone2 hot_node5: Zone2 After one cold node leaves the cluster, all replicas are promoted as primar…

[image] Travis: Is it normal that primaries and replicas shards are not rebalanced between the two cold nodes ? Yes, that's normal. Primaries and replicas do pretty much the same work so there's nothing to be gained by spreading them out as you suggest.
