Description Herman Viaene 2014-12-16 16:05:24 CET
Try to get access to NFS server from MCC.
The NFS-server (Mageia 4) is shown, but none of the two available shares.
The frustrating thing is that I never got it working on a MGA-4 client, that it worked out of the box in the MGA -5 Alpha versions, and now in MG5-B2 it does not again. And the cause is the same: RPC timed out.
From the CLI on the M5 client:
# rpcinfo <serverIP>

Same in MGA6-Beta3.
Comment 2 Herman Viaene 2015-02-25 15:58:44 CET
The strange thing is that actually there is nothing wrong with the nfs installations on both sides (server and client) since at the CLI
mount -t nfs <FQDN>:/<exported map> /mnt/<some map>
works OK and the mounted map and files therein can be displayed in dolphin.
Comment 3 Herman Viaene 2015-02-25 15:59:55 CET
As a side note: I have the same in PCLinuxOS.
Comment 4 Samuel Verschelde 2015-06-01 00:19:51 CEST
Assigning to drakx-net maintainer and adding maintainer of nfs-utils in CC.

Comment 5 Davy Defaud 2015-12-06 02:18:38 CET
I have similar troubles too. Hereâs what I experienced:
- My NFS server is a CentOS 7 exporting via NFSv4 (no problem with NFSv3).
- NFS mount from MGA5 works perfectly with a manual mount command.
- autofs "lazy mount" with special "-host" mount doesnât work on MGA5 (see bug #16195), but does work from a CentOS 6 or 7 NFS client.
- alternative autofs "lazy mount" with auto.net script doesnât work with both MGA5 and CentOS 6 as it's using "showmount -e" command which is having the same problem you discribed.
- but, "showmount -e" command does work from a CentOS 7 client.

The main difference between CentOS 6 (& MGA5) and CentOS 7 is that there is a new daemon named gssproxy that *seems* to act as a bridge between showmount and the NFSv4 server...

I cannot reproduce this anymore in the MGA6 testing ISO's.
Comment 7 Herman Viaene 2019-02-19 17:00:07 CET
Is OK with M7 client.

Status: NEW => RESOLVED
Resolution: (none) => FIXED
