I edited the client vol file generated by glusterd to remove performance translators, but couldn't mount the client after that

Given volfile:
+------------------------------------------------------------------------------+
  1: volume sep8_tcp-client-0
  2:     type protocol/client
  3:     option transport-type tcp
  4:     option remote-host 10.1.10.34
  5:     option transport.socket.nodelay on
  6:     option remote-subvolume /anush/export6
  7: end-volume
