Having issues with nfs/rpc/portmap...

hollywoodb · 04-28-2007, 04:01 PM

I've a CentOS box that is supposed to be serving up a couple NFS shares. I believe it is set up properly.

On a non-CentOS client I'm unable to mount the directories... I have /etc/exports on the host and /etc/hosts set up on both machines. Here's the error I'm getting:

Code:

[root@milan ~]# mount -t nfs4 venice:/home/media /home/media/
Warning: rpc.idmapd appears not to be running.
         All uids will be mapped to the nobody uid.
mount: block device venice:/home/media is write-protected, mounting read-only
Warning: rpc.idmapd appears not to be running.
         All uids will be mapped to the nobody uid.
mount: cannot mount block device venice:/home/media read-only
[root@milan ~]#

The only errors I can find on the server are in /var/log/messages, and I'm not sure they're related:

Code:

Apr 28 15:55:37 venice restorecond: Will not restore a file with more than one hard link (/etc/resolv.conf) Invalid argument
Apr 28 15:57:38 venice restorecond: Will not restore a file with more than one hard link (/etc/resolv.conf) No such file or directory

resolv.conf just has a 'nameserver' line with my router's address.

Do you have rpc.idmapd running on the client (it will show up in ps)? If not you can do a "service rpcidmapd start" and turn it on for future reboots with chkconfig,

No, I didn't realize it needed to be running on the client. ps shows that rpc.statd is running. When I run rpc.idmapd nothing happens, that is it appears to run and exit cleanly. I do have a 'portmap' service, and that is running, but no seperate rpc* services.
