Without anything in the logs, it's really hard. It might be that we started to
do some readahead and that gives troubles to the drive. What's the value of
/sys/block/<device>/queue/read_ahead_kb in 10.3 and 11.1?
Also it would be useful to find out what exactly triggers the noise... Is it
reading any particular file (not exactly the last one)?
Or how long after copying does the sound appear? Maybe you could try running
blktrace just after the copying finished (or during the end of it) so that we
can see whether kernel sends some commands to the drive which make the noise or
what.
I'm just throwing in ideas here because it's quite unclear to me what's
happening...
