Portworx recommends using devicemapper as the default graph driver for container images.

Please follow these instructions to setup Device Mapper for your distribution.

This script can also be used to help with the basic thinpool and devicemapper setup.

Please note the following caveats:

  • This script must be run as ‘root’
  • This script requires one command line argument for the device to be used
  • This is intended to run at docker installation time (and will stop docker if it’s already running)
