Description Pranav Gaikwad 2022-05-12 19:20:40 UTC 
Description of problem:
Data transfer in MTC (Direct or Indirect) does not work when the destination storage is dynamically provisioned AWS EFS PV. This is due to limitations of CSI driver. This needs to be documented as a known issue. An upstream knowledge base article talking about the issue is published here: https://engineering.konveyor.io/posts/mtc-pv-uid-gid-prereqs/

Version-Release number of selected component (if applicable):
1.7.1

How reproducible:
Always

Steps to Reproduce:
1. Migrate data to dynamically provisioned AWS EFS volumes


Actual results:
Migration should succeed. 

Expected results:
Migration fails.

Additional info:
This is actually a limitation that cannot be solved in MTC. It just needs to be documented as a Known Issue.
