NFS mounts

NFS mounts

[Konrad Hinsen]

Hi Guixers,

does anyone have an example of a system configuration that mounts an NFS
share at boot time? It seems that this requires some extra services and
also some additional packages (to have mount.nfs for example).

Konrad.

Indeed, the initrd would need an extra package, like this:

Can you try if it works?

However, we should provide an ‘nfs-utils-static’ package because the
above leads to a very big initrd (the closure of ‘nfs-utils’ is
~200 MiB).

HTH,

I will! However, I am almost sure that this is not sufficient.
For a first test, I installed nfs-utils for manually mounting
my NFS share. It fails because the daemon rpc.statd is not running.
I suspect this will require an additional service, as I don't see
any existing service that refers to rpc.statd.

It compiles, and I can boot the new configuration without any trouble.

Next, I added an NFS filesystem:

      (file-system
        (device "192.168.56.1:/home/hinsen")
        (mount-point "/host/home/hinsen")
        (create-mount-point? #t)
        (type "nfs"))

For "device" I put the string that I would also give to "mount" as an
argument. That's perhaps completely wrong. After rebooting, I get the
error message

  No file system check procedure for 192.168.56.1:/home/hinsen; skipping

So I added

        (check? #f)

to the file system specification. Another reboot, more error messages:

  Service udev has been started.
  failed to start service 'ncsd'
  failed to start service 'guix-daemon'
  ...

plus many others. The only services that start are "udev" and
"loopback".  I can't log in.

Configuration rollback is really nice BTW ;-)

Could you test it in a VM, pass “console=ttyS0” as a kernel argument,
and “-serial stdio” so that we see all the messages on the console?

(You can do ‘guix system vm’ and then modify the command line that it
returns.)

Isn’t it?  :-)

It took a while, but here it is. My config.scm is attached as well.

By default, file systems are automatically mounted at boot time.  To
avoid that, you must add:

  (mount? #f)

> failed to start service 'file-systems'
> failed to start service 'file-system-/host/home/hinsen'

This is the crux of the problem: it tried and failed to mount this file
system, so everything else failed as well (because the ‘file-systems’
service is an essential requirement.)

This is not a great failure mode, but it’s expected here.

HTH!

That works well indeed. But I actually want that NFS filesystem mounted
at boot time, ideally (not strictly required though).

Of course, the real problem is that I cannot mount it at all because
rpc.statd is missing.

Konrad.

Ooh, got it.  Well we could (ab)use the ‘dependencies’ field of
‘file-system’ to introduce a dependency on the rpc.statd daemon startup.

Is there a service that starts rpc.statd? I can't find rpc.statd
anywhere in the Guix source.

Not yet (there’s a couple of NFS-related services but not this one.)
Well, when it exists, we can add that dependency.  :-)
