Re: Fwd: udevtrigger: Initng hangs

Jens Radloff — 2009-12-13T14:31:10

Hi Eric,


Thanks a lot for your hint, now initng does not hang anymore for several 
seconds at 7% of the initialization of my Debian Lenny installation :-) 

For documentation purposes, the file  /etc/initng/system/udev.i now 
contains the following lines:

# wait for the udevd childs to finish
# /sbin/udevsettle
# Request device uevents
/sbin/udevadm trigger
# Watch the udev event queue, and exit if all current events are handled
/sbin/udevadm settle --timeout=300

Well, I am no udev expert, the above-mentioned comments about the 
udevadm options are quotes from the udevadm manpage ;-)

There are two other issues with regard to the initialization of my 
Debian Lenny installation by initng:

1. KDM daemon started twice

At the end of the boot and initng initialization process, the KDE login 
screen is displayed for some seconds, but then it dissappears, instead 
a black screen is visible, and then the login screen is displayed 
again. It seems as if KDM is loaded, then it gets terminated, then it 
gets star

Fwd: udevtrigger: Initng hangs

Jens Radloff — 2009-12-12T17:25:47

Hi,

I would like to use initng 0.6.10.2 in my Debian Lenny installation.

During startup initng hangs for a lot of seconds and thus delays the 
init process, and then continues the initialization of the system. This 
is the message while the init process hangs:

7% system/udev/filldev start
bash_helper[system/udev/filldev]: line 46 /sbin/sbin/udevtrigger: no 
such file or directory

The fix specified at http://www.initng.org/wiki/udevstart unfortunately 
does not provide a solution because in my 
installation /etc/initng/system/udev.i already contains the following 
lines:

# if this directories are not present /dev will not be updated by udev
/bin/mkdir -p /dev/.udev/db/ /dev/.udev/queue/

# send hotplug events
/sbin/udevtrigger

# wait for the udevd childs to finish
/sbin/udevsettle

Any suggestions about how to solve this?

Regards,

Jens

InitNG moving to SF.net

Eric MSP Veith — 2009-11-24T19:16:57

-----BEGIN PGP SIGNED MESSAGE-----
Hash: SHA1

Dear readers of the InitNG mailing list,

today, Ismael and I decided to move the InitNG hosting to Sourceforge. The 
main reason after the current Trac downtime and continued mailinglist issues 
is that we want to spend time with development, not with project 
maintenance. SF.net provides us with the features we need (notably Trac and 
mailing lists), and at the same time lifts a heavy technical management 
burden from us.

I bid you to re-subscribe to the new mailing list. You can find information 
about that on

https://lists.sourceforge.net/lists/listinfo/initng-users

This current mailing list will be taken down in a few days, and subscritions 
will be removed. We will try to maintain the archive. Please refrain from 
today on to post to the old list, thanks.

All current files, settings, and tickets are going to be moved over to 
SF.net. The Git hosting, however, will stay at Gitorious.

Enjoy!

Hey,

subject says it all, initng.org's Trac is down with "internal database

Re: About two minutes latency while bootinginitngservices.

Takeshi MATSUOKA — 2009-11-16T08:44:27

Hi Ismael, Eric and folks,

Sorry for my late response.


Yes, the option of netdev is 'ON' now.
BUILD_NETDEV:BOOL=ON

Thereafter the delay does not occur.
If it is experimental, I want to set it to off.

Thanks a lot!

Takeshi.

Takeshi MATSUOKA — 2009-11-06T11:56:26

Hi Eric,

Thanks for your advice. I'll try to get the stack trace.
If a delay occurs, I'll post it to this ML.

regards,
Takeshi.

Hi Takeshi,

could you please trace InitNG, i.e. attach a gdb to it and when the timeout 
happens, post a stack trace to the ML? I can only make wild guesses here. 
One would be to ask whether your device has any NICs or whether nwpboot 
enables NIC hardware or not.

I fear InitNG gets stuck somewhere in the initng_io_module_poll(int timeout) 
heap. Would be good to know definetly where.

Thanks.

Re: About two minutes latency while booting initngservices.

Takeshi MATSUOKA — 2009-11-05T04:03:30

Hi Eric and Ismael, and folks,


Sorry, this report was wrong, it was not correct time.
I tested it again last night, and confirmed that the latency was just
two minutes.

BTW, I found two minutes delay (not a timer) in
'plugins/netdev/initng_netdev.c'.
probe_network_devices() : initng_global_set_sleep(120);

I changed this value to 60 sec for trial.
The result was following.
Jan  1 00:02:13 MYHOST InitNG: Service service/nwpboot is starting.
Jan  1 00:02:18 MYHOST service/nwpboot: writing done
Jan  1 00:03:18 MYHOST InitNG: Service service/nwpboot is up.

I think my nwpboot service doesn't depend on probing any network 
devices. Would you show me a purpose of this delay?
I want to customize this value if possible.

regards,
Takeshi.

Takeshi MATSUOKA — 2009-11-04T11:11:40

Hi Eric and Ismael,

Thanks for your quick response.
Today this problem occurred again, but the latency was not just two minutes.

I'll try the test with debug output, and trace it with dependent programs.

regards,
Takeshi.

Re: About two minutes latency while booting initngservices.

Eric MSP Veith — 2009-11-03T01:16:39

Welcome to the list!

There's no timeout in InitNG's service handling that produces a "ok" signal. 
At least none that I know about. The great master, Ismael, should verify 
this. ;-)

Let's start by adding some debug output. Could you please modify your 
service that it looks like this:

----%<----
echo $(date) nwpboot
time /usr/bin/nwpboot /root/nwp_program userapp
rc=$?
echo $(date) done nwpboot
exit $rc
---->%----

Let's see how it behaves. :-)

Thanks.

About two minutes latency while booting initng services.

Takeshi MATSUOKA — 2009-11-02T09:35:40

Hi, all,

This is the first time I post to this mailing list.

I'm now trying to use initng for fast booting on our embedded system.
I found a strange latency only once while booting initng services.
After one of service program has done, it took two minutes till 
service is up.
(Normally it takes only 1 sec.)

This program (nwpboot) writes other program to pci, it returns 0 to 
initng after printing 'writing done'.

Outputs by syslog-ng are below:
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Dec 12 01:56:19 MYHOST InitNG: Service system/modules is up.
Dec 12 01:56:19 MYHOST InitNG: Service system/mountfs is up.
Dec 12 01:56:34 MYHOST InitNG: Service service/nwp_exp is up.
Dec 12 01:56:35 MYHOST InitNG: Service service/lm_exp is up.
Dec 12 01:56:39 MYHOST service/nwpboot: writing done (*by printf)
            ^
            | 2 minutes latency
            v
Dec 12 01:58:39 MYHOST InitNG: Service service/nwpboot is up.

The definition of nwpboot service is below:
