Expanding persistent data volumes when using Docker for AWS CE

(Khou) #1

Expected behavior

SSHing to the instance and installing resize2fs will allow the user to expand the filesystem of partitions attached by Cloudstor or REX-ray plugins.

Actual behavior

Not possible, devices aren’t listed (due to the login of docker@ip being a container on top of the host instance)

Steps to reproduce the behavior

  1. Start a cluster with Docker for AWS CE
  2. Launch a service that uses a Cloudstor EBS volume or install REX-ray and do the same
  3. Scale the EBS volume through the AWS console
  4. SSH to the instance and try to scale the partition
