Seldon building on Kubernetes

[Anto188bas]

Hi, I installed Kubernetes on AWS using the official guidance. Now, I have a node master (m3.medium) and two workers (t2.medium) on which I need to run Seldon. I'm using the official guidance: http://docs.seldon.io/install.html But when i run the seldon-up.sh on Kubernetes, I obtained the following error during the creation of containers seldon-control-3388397084-pvr8k and influxdb-grafana-3089120915-fzxt4 :

Multi-Attach error for volume “pvc-d97313ee-93e1-11e7-ae85-02f1ec9e7a70” Volume is already exclusively attached to one node and can’t be attached to another Unable to mount volumes for pod “influxdb-grafana-3089120915-fzxt4_default(e21ad2fc-93e1-11e7-ae85-02f1ec9e7a70)“: timeout expired waiting for volumes to attach/mount for pod “default”/“influxdb-grafana-3089120915-fzxt4". list of unattached/unmounted volumes=[storage] Error syncing pod

How could I solve this issue?? Thank you for your time in advance.
