ML370 G2 - Debian Sarge - Shutdown Problems

Arthur Kant_1 — Tue, 09 Aug 2005 13:22:12 GMT

We have ML370 G2 (1 CPU) latest firmware, running a hardware RAID1 on a 641/642 Smart Array adapter.

I have installed Debian Sarge on the system and everything work great, except the system always locks or hangs on shutdown when "Sending TERM Signal to all processes" am I missing something here? I am running the 2.4.27-2 kernel have tried upgrading via apt-get to SMP version of this kernel no changes. Should I move to 2.6 ?? I want to stay at 2.4 if at all possible.

Thanks all!

Arthur,

See if you can find anything in the log files to point us in the right direction.

If u had a lot of services started which are resource hungry , then this may hang the machine at the "Sending TERM Signal to all processes" . Try booting to runlevel 2 and shutdown the machine . If it is shutting down properly , then remove the unnecessary services from ur startup .

Please ensure that you have enabled APCI both in BIOS and in the debian kernel.

Linux kernel requires advanced power management functionalities to handle auto power off of servers during shutdown. The kernel you are using should have this functionality unless it is disabled intentionally during boot time.

Also check the kernel boot parameters and ensure you dont have apci=off as one of them, if so try removing it and see whether it works.

It was a very small installation nothing really but the command line and software I needed to run asterisk.

Stupid question, how do I change the runlevel as specified in your reply at boot?

Yes this was enabled in BIOS and in the kernel from what I know. I actually though this was CAUSING the problem so tried to disable in the bios and the kernel... but that just caused more problems... but I have the machine back to the way it was problem continues.

2.6 kernel offers a lot of performance and stability advantages. that alone is worth it.

I would take a little more time though looking for an actual cause.

df -H

Does /var have enough space?

Lets check /var/log/messages for an error message.

shut the system down, let it hang for an hour or two and see if it finishes or the log gets updated.

If you find more data, please post back to this thread.

Well I reinstalled Sarge with 2.6.8 kernel and that fixed the problem. I was told that by the time shutdown process got to the "sending all processes" the term signal that all drives are umounted from r+w ? So there would be know log... I check the log also before I did this and nothing looked wierd.

Also as tried letting the system hang on that prompt when it was locking for over 12 hours no avail ;( .. I really wanted to use 2.4 but I guess 2.6 will be ok...

Now I was reading that HP sells support packages for Debian now? Do any of you use Debian on HP hardware in production? What type of application?
