Expanded Size of an AWS EBS Volume is Not Visible to the Delphix Engine (KBA5196)

A Delphix engine running on AWS has additional storage space added to it by expanding the size of its existing EBS volumes.  However, the additional space is not visible to the Delphix engine which continues to show the original EBS volume size.

The Delphix engine is currently unable to see the expanded size of an EBS volume without a reboot.  The engine should be rebooted in order to see the new size and the space can then be added to the storage pool for use.

If a new EBS volume is added to the engine, this will be seen without requiring a reboot.
