If your server is reporting that these directories are all contained in one big volume, then that will suffice to confuse the client. One way to work around this, is to tell the client that the subdirectories are on different volumes. You can do that using the "nosharecache" mount option. Beware, however, that if you have hard linked files that appear under more than one of these mountpoints, then the client will treat them as if they are completely separate files for the purposes of caching and close-to-open cache consistency checking.
