[SOLVED] nfs mount failure after nfs-utils update

After upgrading nfs-utils on my server from version 1.2.9-5 to version 1.3.0-2, the NFS shares for my diskless workstations fail to mount. The boot process hangs and finally times out with the message:

ERROR: Failed to mount the real root device

I don't see any NFS error messages in the journal on the server. Other than the nfs-utils upgrade, nothing changed in my config. I have not upgraded nfs-utls on the workstations. Could the problem be that the server and client versions of nfs-utils need to be identical? I did not see that on the NFS wiki page.

Haven't gotten there yet.  Probably a bug in the update.

Re: [SOLVED] nfs mount failure after nfs-utils update

For some reason, this didn't show up when I upgraded nfs-utils.  Luckily I follow [arch-dev-public] for my machines that run [testing], and I caught it a while back.

...
post_upgrade() {
  if [ "$(vercmp $2 1.2.9-5)" -lt 0 ]; then
cat << 'EOM'
  ==> IMPORTANT 1.3.0 NFS UTILS CHANGES:
  ==> This is a rather important upgrade, you are going to have to change systemd services files.
  ==> NFS-SERVER:
  ==> systemctl enable nfs-server.service
  ==> NFS-CLIENT:
  ==> systemctl enable nfs-client.target
  ==>
  ==> Extended configuration options for NFS (clients & server) are available in:
  ==> /etc/conf.d/nfs-common
  ==> /etc/conf.d/nfs-server
  ==> Please change them to your needs.
EOM
  fi
}

Edit: Basically, we are now apparently finally able to use the upstream service files instead of Arch specific ones.  So you will probably also have dead symlinks in /etc/systemd/system/multi-user.target.wants as well.

@ww - Good find, you should update the wiki: https://wiki.archlinux.org/index.php/Nfs

Re: [SOLVED] nfs mount failure after nfs-utils update

I may have the same issue. After the latest upgrade, shares on my Archlinux server fail to mount on my Kubuntu laptop. nfs.mount just times out.

Enabling nfs-server.service in systemd, as suggested in the thread,  fails to solve the issue. Is there anything else I am supposed to do to restore mounting? I looked at  /etc/conf.d/nfs-common but did not find it very informative, I must say.

Help appreciated.

Cheers,

Stefano
