When you shut down a node, the allocation process waits for
|
|
`index.unassigned.node_left.delayed_timeout` (by default, one minute) before
|
|
starting to replicate the shards on that node to other nodes in the cluster,
|
|
which can involve a lot of I/O. Since the node is shortly going to be
|
|
restarted, this I/O is unnecessary. You can avoid racing the clock by
|
|
<<shards-allocation, disabling allocation>> of replicas before shutting down
|
|
the node:
|

PUT _cluster/settings

"persistent": {

"cluster.routing.allocation.enable": "primaries"

}

}
