This is correct behavior. If you want to see the files underneath a
mounted file system, you need to use the union option on the
mount. sysinstall doesn't expect you to have live file systems
mounted, so doesn't do that.

Are you positive nothing was in use on it? In particular, could
sysinstall have opened something on it? In any case, unmounting the
file system causeing that functionality to return is expected.
