Migrating KVDB to different nodes in k8s

[Aleksey_Usov]

Hello. What is the procedure for moving KVDB processes from one set of nodes in k8s or OpenShift to another? The only thing I was able to achieve is to start etcd on the target set by adding -kvdb_cluster_size “5” parameter to portworx DaemonSet, but there doesn’t seem to be a way to stop it on the old nodes. One would think that labeling all target nodes with px/metadata-node=true and all old nodes with px/metadata-node=false label would simply shut etcd down on the latter, but no luck. Removing -kvdb_cluster_size, which effectively sets it to 3, didn’t help either. I’d like to know if there is a way to do this via portworx itself before resorting to removing etcd endpoints via etcdctl.
