Don't do that then. Do you have any reason to suppose that buffers were
already written to the top level system yet, or that mounting the same
device twice will caus eanything but pain and confusion and much
wailing and gnashing of teeth?

       Sir I tried the same steps with a RAID1 array

Don't.

        Hoping for your reply.Thanking you in

Try a test that has actually got some sense to it and will not destroy
your data! Such as faulting one device out of the raid. Then you have
to be reading from the other one, no?
