Nomad load distribution - 3 clients - 1 empty

Hi there :slight_smile:

we’re using a nomad cluster with 3 client nodes.

Everything work fine but I noticed that load is only distributed onto 2 of the 3 nodes. One node seems empty all the time. Maybe it’s a config issue or normal behavior.

It’s fine for rolling upgrades of the cluster but it would be nice if load would be evenly distributed to all 3 nodes.

Is that supported by nomad? (Nomad v1.6.1)

Hi @bartling.jan,

This will be as a result of bin-packing, the default scheduling algorithm Nomad uses when performing workload placements. The scheduling concepts page has more information on this, if you wanted a deeper dive.

Nomad also supports the spread algorithm which can be modified using the operator scheduler API endpoint or the related CLI command.
