CVO failover/giveback: what happens to the I/O in flight?

[DMWNTAP23]

During a Windows client "copy/paste" operation on a 10GB file, the user [purposely] failed over one CVO node to the other as a test.  The copy operation was about halfway done when the f/o started, and the user got a pop-up saying the copy got aborted, and "Do you want to restart?  Y/N"

1. If they say "Yes", does the copy restart where it got interrupted (checkpoint/restart function), or does it start over from the beginning once node2 takes over?

2. They actually said "No" to the restart question when they tested this.  Would they expect:

      a. The file to be "wiped" from the target client (no data copied)?

      b. The file to be partially copied over, but not completely.  

      c. The Windows Explorer on the target client shows the file completely copied over, but is unreadable?

Which hyperscaler? Is this in AWS multi AZ by chance? 

If so are you using the floating IP rather than the static IP’s?

[DMWNTAP23]

It's AWS, single AZ with one CVO HA pair.  User copied (used Windows "copy/paste") file(s) from an external Windows machine (not a CVO client) TO a Windows client of the CVO instance.  No floating IP required.

Mmmm interesting use case testing... would love to have an official answer on this. Anyone from NetApp ?
