[Bug 1026111] Re: NFS shared folder not available after boot (RPC issue)

[Jos Bijster]

Even though this tickit seems to be expired, I'd like to add the
following.

I've been having the same problem in 12.04. I followed the guide at
<https://help.ubuntu.com/community/SettingUpNFSHowTo> and came up with a
complaing nfs service saying that "rpc.statd is not running".

I fixed the problem by adding "portmap : ALL" to the last line of
/etc/hosts.deny instead of "rpcbind : ALL", and adding "portmap :
192.168.1.251" to the last line of /etc/hosts.allow instead of "rpcbind
: 192.168.1.251".

192.168.1.251 is the ip-address of my Synology NAS at home. Replace this
with your server's ip-adress, should you decide to give this a try.

Everything else in the "SettingUpNFSHowTo" guide is accurate for as far
as I can tell. No need to deviate from the guide in any other way.

I'm not at all sure why this fixes it, I'm just glad that it does.

Title:
  NFS shared folder not available after boot (RPC issue)

Status in “nfs-utils” package in Ubuntu:
  Expired

Bug description:
  After a new install from scratch, there is a problem with rpcbind and the nfs client : 
  after boot, the shared directories are NOT mounted and if I try to mount them manually:
  > mount -a
  it says
   mount.nfs: rpc.statd is not running but is required for remote locking.
   mount.nfs: Either use '-o nolock' to keep locks local, or start statd.
   mount.nfs: an incorrect mount option was specified

  the process list gives:

  > ps aux | grep rpc | grep -v grep
  root       846  0.0  0.0      0     0 ?        S<   Jul17   0:00 [rpciod]
  root       876  0.0  0.0   2860   660 ?        Ss   Jul17   0:00 rpc.idmapd

  In syslog, I can see that rpc.statd failed to start:

  The solution I have found is to start rpcbind manually
  > rpcbind 
  then mounting works fine:
  > mount -a
  and after that, the process list gives:
  > ps aux | grep rpc | grep -v grep
  root       846  0.0  0.0      0     0 ?        S<   Jul17   0:00 [rpciod]
  root       876  0.0  0.0   2860   660 ?        Ss   Jul17   0:00 rpc.idmapd
  root      5700  0.0  0.0   2692   852 ?        Ss   08:54   0:00 rpcbind
  statd     5705  0.0  0.0   3152  1252 ?        Ss   08:54   0:00 rpc.statd --no-notify

  
  Everything used to work perfectly with nfs client running Ubuntu 10.04 but since then, portmap has been replaced by rpcbind. This happens on three different computers running Ubuntu 12.04. All the other clients (still under 10.04) do not face that problem.

   /etc/fstab on the client:
  myserver:/exports/communs    /Reseau/Communs        nfs     defaults,sync,rw        0       0
  myserver:/exports/software     /Reseau/Logiciels           nfs     defaults,sync,rw        0       0
