Hi, How do I increase the underlying disk size for Portworx and Portworx pick the new disk size up for the storage pool? Is that done automatically? For e.g., I am using AWS EBS volumes as backend disks for Portworx. If I resize my EBS volumes, will Portworx pick it up automatically or is there a procedure I need to go through?

Any help is much appreciated.

If you resize the EBS volume, You need to run the “pxctl service pool update --resize" command to use the maximum available physical storage.  
Documentation can be found here `https://docs.portworx.com/reference/cli/service/#pxctl-service-pool-update`

Make sure to check if the OS sees the new disk size by running “lsblk” before proceeding to Pool update
