Force a panic dump

[Hawki]

Can someone let me know how to force a panic dump on a Linux server. I need to because I have a system thats acting out of control sometimes before it shutsdown.

It depends of your distrib for example redhat can only make dumps by network.

For redhat have a look to:

In the netdump package there is a little test programme called crash.c. If you compile that and then insmod it into the kernel it will cause an instant panic.

Gee, why would someone WANT to force a kernel panic?

And here, I've been doing it accidently all these years... <ROFL>



Just my 2¢

There is a reason for everything and in this case I work where we have hundreds of UNIX system, Sun, HP and Linux. Sometimes we have systems that act up and it would be nice to see why a system is having a problem. This is because we have customers and we have to report to them.

By the way RedHat also supports diskdump, I'm not sure why Gloups said it only supports dumps over network?

[Hawki]

yes, I need somthing that dumps to the drive. So diskdump dumps to the hard drive? I do not need to work over a network. This is a RedHat server
