            I just got my test bed back and tried this out.

            lctl list_param *.OST000.readcache

            obdfilter.lustre-OST0000.readcache_max_filesize

            obdfilter.lustre-OST0002.readcache_max_filesize

            osd-ldiskfs.lustre-OST0000.readcache_max_filesize

            osd-ldiskfs.lustre-OST0002.readcache_max_filesize

            Now if you try obdfilter version it gives a warning not to use it anymore.
