Thanks. This procedure worked, although rather than disabling md-cache, I used
a switch to disable readdirp operations "*md-cache.force-readdirp=no".
glusterfs --volfile-id=/t --volfile-server=gprfs018 /mnt2 --use-readdirp=no
--xlator-option "*dht.use-readdirp=no" --xlator-option
"*md-cache.force-readdirp=no"
