Decommission

curl -v "http://127.0.0.1/metaNode/decommission?addr=127.0.0.1:9021"

remove the metaNode from cluster, meta partitions which locate the metaNode will be migrate other available metaNode asynchronous

Parameters
Parameter Type Description
addr string the addr which communicate with master

Threshold

curl -v "http://127.0.0.1/threshold/set?threshold=0.75"

the used memory percent arrives the threshold,the status of the meta partitions which locate the metaNode will be read only

Parameters
