[Test] Test entry transaction crash consistency with fops
Testcase 1: Test entry transaction crash consistency : create - Create IO - Calculate arequal before creating snapshot - Create snapshot - Modify the data - Stop the volume - Restore snapshot - Start the volume - Get arequal after restoring snapshot - Compare arequals Testcase 2: Test entry transaction crash consistency : delete - Create IO of 50 files - Delete 20 files - Calculate arequal before creating snapshot - Create snapshot - Delete 20 files more - Stop the volume - Restore snapshot - Start the volume - Get arequal after restoring snapshot - Compare arequals Testcase 3: Test entry transaction crash consistency : rename - Create IO of 50 files - Rename 20 files - Calculate arequal before creating snapshot - Create snapshot - Rename 20 files more - Stop the volume - Restore snapshot - Start the volume - Get arequal after restoring snapshot - Compare arequals Change-Id: I7cb9182f91ae50c47d5ae9b3f8031413b2bbfbbf Co-authored-by: Vitalii Koriakov <vkoriako@redhat.com> Signed-off-by: Vitalii Koriakov <vkoriako@redhat.com> Signed-off-by: kshithijiyer <kshithij.ki@gmail.com>
