NFS Mounts before network up

bocochoco · 01-23-2012, 12:58 PM

I've got my home directories on a nfs mount that should mount at boot. It tries to mount them before the network comes up, for some reason. I've read around, and it seems this happens often to a number of people. I can't seem to find a fix that works. Sometimes it mounts fine, other times not.

I've enabled the NetworkManager-wait-online.service service, but it doesn't seem to affect anything.

I've tried creating a script in init.d that runs mount -a and adding it to chkconfig at runlevel 3,4,5; that didn't help either.

Users are able to login without their home directories mounted, but there are scripting problems.

Any ideas how to resolve this?

Hi bocochoco,

Ideally any of the network services should not start before the network comes up. You need to check the start and kill scripts of the default run level of the server.

Which distribution you are running on?

Whoops, forgot to post that. I'm running Fedora 16 LXDE spin.

Systemd seems to take care of the boot process. I've tried adding NetworkManager-wait-online.service to the NetworkManager.service unit's Wants, but that didn't seem to do anything. Not really terribly familiar with how systemd operates, so I'm at a loss as to how to fix this.

Which is the default run level your system boots in. If it boots in runlevel 5 then post the output of the following:

Code:

ls -l /etc/rc.d/rc5.d/

If it boots in runlevel 3 then post the output of the following:

Code:

ls -l /etc/rc.d/rc3.d/

Not sure then post the output of both along with the output of the following:

Code:

cat /etc/inittab

It's booting into runlevel 5

Code:

Are you sure this is the full output because I do not see nfs services listed in their. Type the following command and let me know the output:

Code:

chkconfig --list nfs

bocochoco · 01-23-2012, 01:57 PM

Not sure how useful the chkconfig output is going to be, so I've also posted the output of systemctl --full

chkconfig --list

Code:

[administrator@belgarath ~]$ chkconfig --list

Note: This output shows SysV services only and does not include native
      systemd services. SysV configuration data might be overridden by native
      systemd configuration.

I think that the two nfs mounts in fstab are being added to systemd as sayre.mount and home-aos.mount. There are no files for them in /lib/systemd/system, I'm not sure where they come from; /etc/fstab is just my guess. Googling suggested that adding comment=systemd.automount to the entries in fstab would solve the problem, but that didn't help.

We can give following a try. Add the following line to your /etc/rc.local file:

Code:

echo "mount -a -o remount" >> /etc/rc.local

Reboot the machine and see if you get your nfs share mounted successfully.

bocochoco · 01-23-2012, 02:32 PM

Well, there wasn't a /etc/rc.local file to begin with. I created one with that line in it, but it didn't affect anything.

Code:

#!/bin/sh

mount -a -o remount

This is very strange..

In fedora 16 it's

Code:

/etc/rc.d/rc.local

Kind regards

T3RM1NVT0R · 01-23-2012, 02:36 PM

Well /etc/rc.local file is linked to /etc/rc.d/rc.local. As I read from the following document: http://docs.fedoraproject.org/en-US/..._Sysadmin.html

/etc/rc.d/rc.local is no longed included. However, you can create one and make it executable and it should run after reboot. You can create one under /etc/rc.d/rc.local, put the line I mentioned in my previous post, make it executable and reboot. See if that works.

bocochoco · 01-23-2012, 03:54 PM

I think that I've solved it. I changed my fstab lines to not auto mount it, and added comment=systemd.automount to the options.

Then I added into /etc/rc.d/rc4.d/S99livesys-late, right after it source /etc/init.d/functions

mount /home/aos
mount /sayre

Now, they're both mounted before the user can log in, and they don't do so until after the network is up.

Thank you for your help with this.
