[Test] Validate copy of file
This test script covers following scenarios: 1) Sub-volume is down copy file where source and destination files are on up sub-volume 2) Sub-volume is down copy file where source - hashed down, cached up, destination - hashed down 3) Sub-volume is down copy file where source - hashed down, cached up, destination hashed to up 4) Sub-volume is down copy file where source and destination files are hashing to down sub-volume 5) Sub-volume is down copy file where source file is stored on down sub-volume and destination file is stored on up sub-volume 6) Sub-volume is down copy file where source file is stored on up sub-volume and destination file is stored on down sub-volume Change-Id: I2765857950723aa8907456364aee9159f9a529ed Signed-off-by: sayaleeraut <saraut@redhat.com>
