Problem with latest RH kernel

Steven E. Protter — Mon, 23 Dec 2002 21:12:14 GMT

Saturday night I downloaded and installed the latest Red Hat Kernels.

My system is using grub, and Red Hat's RAID implementation. The install on my test server went without problem.

After boot, the system hung, at kernel load.

Was this a RAID issue.

I recovered by switching the boot through the grub interface to the old kernel.

Then I changed, /etc/grub/grub.conf to set startup to the old kernel.

I got little useful information from the os.

Any thoughts? Is it RAID? Am I stuck with this kernel until I upgrade to RH 8? I'm not going to that until RH 8.X is solid which means another year, based on the 7.X cycle.

When you say "hung, at kernel load.", what was on the screen at the time?

When you say you're using "Red Hat's RAID", do you mean using the 'md0' type devices and software RAID (which isn't RH's implementation, it's a GNU Linux implementation) ?

It was in the starup screen, prior to the Red Hat Boot Loader, there had yet to be hard disk detection, the WDXXXX stuff for the two mirrored drives.

System setup is as follows: Installed Red Hat 7.2, used the software mirroring you can configure as part of the gui disk druid setup.

I did everything raid 1/0, 40 G Disk to 40 G disk.

As to the actual message text, I'd have to boot into it again, but it had passed the grub screen and loaded the bigmem kernel. I can boot the system tonight, since web traffic is often pretty slow December 24.

So, stand by for more info I guess.

I am planning a reboot this coming weekend.

Its really hard to play with this machine, since its a production server.

Anyone wishing to help, please put this on email notify.

I would like to know how to get rid of unneeded kernels, since now I have nine.

getting rid of unwanted kernels is as easy as removing the files from the /boot/ directory, and modifing the 'grub.conf' to not address them..

Thank you Stewart.

Very much. I'll address that.
