Indeed we are using UNLOAD of cores before shutting down extra replica
nodes, works well but already said, it needs such nodes to be up.
Once UNLOADed it is possible to stop them, works well for our use case.
But if nodes are already down, maybe it is possible to manually create
and upload a cleaned /clusterstate.json to Zookeeper ?

Unloading a core is the known way to unregister a solr node in zookeeper
(and not use for further querying). It works for me. If you didn't do that
like this, unused nodes may remain in the cluster state and Solr may try to
use them without a success. I'd suggest to start some machine with the old
name, run solr, join the cluster for a while, unload a core to unregister
it from the cluster and shutdown host at the end. This way you could have
clear cluster state.

Thanks, I was actually asking about deleting nodes from the cluster state
not cores, unless you can unload cores specific to an already offline node
from zookeeper.
