Gentoo boots to fast, network related services don't start

Message

Kasumi_Ninja · Post by **Kasumi_Ninja** » Thu Jul 31, 2008 7:34 pm

Every time I boot nfsmount and ntp-client fails because my network isn't running yet. I searched the forums and found a fix, however since the fix is 2 years old I wonder if things have changed in between. Is this the best way to solve this problem? Are there other solutions? Will it eventually be solved?

Code: Select all

/etc/conf.d/rc
RC_NET_STRICT_CHECKING="yes"
rc-update add net.eth0 boot

Edit:
Will the parallel boot option help?

Aniruddha,

Thats not a fix its a dirty hack that will haunt you.
It doesn't really start eth0 in the boot runlevel, it forces eth0 and everything that eth0 depends on into to boot runlevel as well.

Do you have the auto or defualts options set for your nfs mount in /etc/fstab ?
If so you need something like

Code: Select all

# An NFS mount to see whats on Eccles without logging in
# eccles:/home          /mnt/eccles     nfs     bg,_netdev,rsize=8192,wsize=8192

Hi Ned,

Thanks for the help! I have the following options in fstab for nfs:

Code: Select all

user,rw,async

However this doesn't explain why ntp-client doesn't run

Maybe it's time to fill a bugreport?

Aniruddha,

The boot sequence tries to mount your nfs with local file systems and cant because the network is not up when it tries.
bg,_netdev, tells mount to background this mount if it fails and that its a network device.

Once the network is up, the mount will complete

Thanks for the tip, is there such a solution available for ntp-client as well?

ntp-client should automatically start when net.eth0 eventually comes up. Are you just receiving the error message or is ntp-client stopped/inactive after your perform an 'rc-status' ?

Aniruddha,

ntp-clent should depend on networking. Exactly what that means depends on how you have set

Code: Select all

rc_depend_strict=

in rc.conf.
If you have more than one network interface in the default runlevel, setting ="NO" means that dependent services can start when the first interface comes up. That can make ntp-client fail, if the first interface up does not provide your internet connecion.

Setting ="YES" means all the defined network interfaces must be started ... this means that your internet connection should be there too.
However, on a laptop where you may use one, another, or all interfaces in different combinations you need to set code]rc_depend_strict="NO"[/code]and ensure your network interfaces are started in the right order.

Putting net.eth0 in the boot runlevel normally means that net.lo will be up first, and you will never find a ntp server on lo, so ntp-client is bound to fail.

This is my new fstab, unfortunately nfsmount still fails

Code: Select all

#nfs
192.168.1.111:/mnt/mount1       /mnt/mount1     nfs     bg,_netdev,user,rw,async   0 0
192.168.1.112:/mnt/mount2       /mnt/mount2    nfs     bg,_netdev,user,rw,async   0 0
192.168.1.1113/mnt/mount3   	/mnt/mount3   	nfs     bg,_netdev,user,rw,async   0 0

@demarc
The ntp-client service is service is running, but because it updates only once (during boot) this means the time doesn't get adjusted.

Do you mean I have to set the RC_NET_STRICT_CHECKING option in /etc/conf.d/rc to yes? I can't find such setting in /etc/rc.conf.

Aniruddha,

My paste was from baselayout2 with OpenRC. baselayout1 has a different control file layout and I don't have baselayout1 any more.
However, that setting is there somewhere.

I changed the settings in /etc/conf.d/rc, unfortunately this didn't help

I guess I have to install baselayout 2 then

Aniruddha,

Code: Select all

select() to /dev/rtc to wait for clock tick timed out

Do you have a /dev/rtc ?
The kernel config changed in this area around 2.6.24 and it was off by default.

Code: Select all

 * Setting clock via the NTP client 'ntpdate' ...
Error : Temporary failure in name resolution
 * Failed to set clock

DHCP has either failed, returned you a link-local address or not set up a nameserver in /etc/resolv.conf.

Your services could also be in a mess. What does

rc-update --verbose

show?

Hi Ned,

First things first; enabling the rc_parallel fixed this problem. Now the nfs partitions get mounted and the network time gets synchronized, I don't have a clue why this works though.

Code: Select all

rc_parallel="YES"

I do have a /dev/rtc. Here's the output of rc-update --verbose:

Aniruddha,

That all looks good. I like alsasound in default rather than boot but I'm paranoid about things not needed for boot preventing booting.

As rc_parallel="YES" fixed it, I guess you have found a race condition, which would indicate that the dependancies in the /etc/conf.d/* files you use are not specified properly.

Time to file a bug.

Ok, thanks for the help I'll file a bugreport. Btw I'm switching back to the previous baselayout since I've had to many problems (no tty terminals, ati 3s acceleration isn't working anymore).
