Install `quota-rpc` and activate `rpcbind` to allow quota queries from nodes other than the NFS server

[mboisson]

In principle:

sudo yum install quota-rpc
sudo systemctl unmask rpcbind
sudo systemctl unmask rpcbind.socket
sudo systemctl start rpc-rquotad

on the NFS server. However, from RedHat's documentation, it needs securing:

The rpcbind service is a dynamic port assignment daemon for RPC services such as NIS and NFS. It has weak authentication mechanisms and has the ability to assign a wide range of ports for the services it controls. For these reasons, it is difficult to secure.

See https://docs.redhat.com/en/documentation/red_hat_enterprise_linux/7/html/security_guide/sec-securing_services#sec-Securing_rpcbind

Selon la doc:
Securing rpcbind only affects NFSv2 and NFSv3 implementations, since NFSv4 no longer requires it. If you plan to implement an NFSv2 or NFSv3 server, then rpcbind is required, and the following section applies.

On semble utiliser NFSv4, donc on n'aurait pas besoin de rpcbind, ni de le sécuriser.

En pratique par contre, ça ne semble pas marcher
