[solved] NFS Server not working after systemd migration

Hi All,

I have a few directories exported via NFS to my wife's ubuntu box.

The shares ceased to work after I migrated to systemd (as well as syslog, but this is another story)

on the client side :

You need quite a lot of services and some pseudo file systems mounted for nfs to work properly. When I switched to systemd there weren't any service files so I wrote my own. Took me a while, since it was a bit of a hassle to find out the right order and what I actually need. This is my setup for nfsv4:

proc-fs-nfsd.mount:

Thank you for such a long and precise answer !

Right now, I am not on my gentoo box, but I will try this in a few days.
I will write down some feedback then.

Thanks, Kompi!

I'm not the original poster but I had the exact same problem. I used your service files, not to directly execute but as a guide to find out what was missing. At this point, there are service files. They just don't seem to be entirely complete or documented. I determined that all I needed was the stock rpc-mountd.service

# systemctl enable rpc-mountd.service
# systemctl start rpc-mountd.service

And I'm golden! It is possible that another supplied service is necessary that I have enabled in my fumbling but no new service were needed.

bleh please file bugs to the tracker so the packages come as "just works" for systemd

Hello,

I am the original poster.

It is still not working for me, nfsd.service fails to start at boot

What does journalctl report?

journalctl is the "native" logging method for systemd. If syslog isnt' running, it is your best bet to figuring out what is going on.

Is it possible that, in adding support for systemd in your kernel, that you inadvertently removed support for nfs? That would prevent nfsd from running.

If you still have the openrc files you could run /etc/init.d/nfs to determine if nfs is truly broken of it is just a systemd problem.

Here are the logs related to nfs

But, if it is running, why my wife's box cannot mount the shared directories ?

Should I investigate on it ?

I stopped it and restarted it via systemctl. Remote connexion is still not possible.

I also have had to append real_init to my grub.conf to make it boot with systemd

im not sure if its systemd that the bug is filed against, im pretty sure it would be against nfs.

666, I did file https://bugs.gentoo.org/show_bug.cgi?id=496832

But it turned out to duplicate https://bugs.gentoo.org/show_bug.cgi?id=484768

Which was closed as WONTFIX through peculiar reasoning.

Sorry to answer so late, but I have had some urgent stuff to do last couple weeks.

So if this is not a bug, how can I have my nfs shares to work ?

If needed I can restart it form the start if I am sure that will fix the problem. Do you know an up-to-date how-to (including systemd) ?

Nitro, the bug/nonbug in question is the lack of dependency for rpc-mountd. While you may have this problem too, it clearly isn't the only issue.

Previously, it appeared that you had another instance of nfsd running that was interfering with launching via systemd. You stopped and restart nfsd using sytstemd but that may not be sufficient. If nfsd was not started by systemd, then systemctl stop nfsd may not kill it. Check for it with ps (ps -eaf |grep nfsd). If necessary, you can pkill nfsd. Once you are sure there is no nfsd running, then you start it systemctl.

It seems that nfsd is started by systemctl

Now, with nfsd not running, if you start it with systemctl, does it still complain about "Address already in use"?

No complaint at all, it starts flawlessly

Is rpc-mountd running?

Nitro_146 · Posted: Tue Jan 21, 2014 10:20 pm Post subject:

Not, it is not.

ese002 · Apprentice Joined: 20 Sep 2006 Posts: 155

Is rpc-mountd.service enabled?

systemctl enable rpc-mountd.service
systemctl start rpc-mountd.service

If that works, then restart nfsd and see if it works.

Unfortunately, it does not work

If by «edit your copy» you mean modify some file, I don't remember exactly. I have this issue for 2 month now and I have tried several fixes.

Should I backup my config file, unmerge nfsd (and some other package) and emerge it again ?
