[Bug 1510137] Re: Cannot start nfs server, get errors about "nfsd" filesystem being unknown

[Timothy Miller]

I think I've figured out something about what's going on here.

Either:
(1) The Wily installer has bugs that occur when you install to /dev/sdb1, resulting in kernels not being setup properly,
OR
(2) If the Wily installer sees any kernels, it doesn't install the latest one.

So this clean install I mentioned, well, it's MOSTLY clean.  I didn't
format the drive.  I just installed over what was there.  The installer
didn't install the latest kernel, which caused all sorts of problems.

I have another system where I UPGRADED to 15.10 server, and that also
did not install the correct kernel!

Title:
  Cannot start nfs server, get errors about "nfsd" filesystem being
  unknown

Status in nfs-utils package in Ubuntu:
  New

Bug description:
  When I installed this 15.10 system (clean install), I selected that I
  wanted to install an NFS server, so it should have had all of the
  packages installed, and it should have been a simple matter of editing
  /etc/exports and restarting the service, but not only was nfs-kernel-
  server NOT installed, but after installing, I can't get it to start.

  First, I get this:
  # service nfs-kernel-server restart
  A dependency job for nfs-server.service failed. See 'journalctl -xe' for details.

  So I do 'journalctl -xe', and I see stuff about missing dependencies.
  Initially, I got errors about "nfsd" being an unknown filesystem, and
  Googling that didn't get me terribly far.  Here's the meat of what I
  see:

  Oct 26 10:48:17 thing1 systemd[1]: nfs-idmapd.service: Job nfs-idmapd.service/start failed with result 'dependency'.
  Oct 26 10:48:17 thing1 systemd[1]: run-rpc_pipefs.mount: Unit entered failed state.
  Oct 26 10:48:17 thing1 mount[1587]: mount: unknown filesystem type 'nfsd'
  Oct 26 10:48:17 thing1 systemd[1]: proc-fs-nfsd.mount: Mount process exited, code=exited status=32
  Oct 26 10:48:17 thing1 systemd[1]: Failed to mount NFSD configuration filesystem.

  I did an apt-get update and upgrade, and then I got an error about
  nfs-common having an error while being configured, so I tried to
  configure it with "sudo dpkg --configure -a", and I get errors about
  both nfs-common and nfs-kernel-server not being configured.
  Configuring nfs-common again, I'm told once again to look at
  'journalctl -xe', and the main errors I see are all about unmet
  dependencies and this one:

  Oct 26 10:38:32 thing1 mount[5635]: mount: unknown filesystem type 'rpc_pipefs'
  Oct 26 10:38:32 thing1 systemd[1]: run-rpc_pipefs.mount: Mount process exited, code=exited status=32
  Oct 26 10:38:32 thing1 systemd[1]: Failed to mount RPC Pipe File System.

  Googling this, someone suggested a reboot, so I did that, but all that
  happened was that the "nfsd" error game back.

  Note that in no instructions I've seen is mentioned to do anything
  with "nfsd", nor do I know of any place that it is specified.  It
  appears that 15.10 nfs support is pretty badly broken.  I would mark
  this bug as CRITICAL since it's taken me out of commission completely.
