using stock kernel with fedora core 4, why make it so hard?


I need to use a stock linux kernel (2.6.13.4) for some hard-real time stuff, and I keep having issues with LVM. Specifically, when I go to reboot with the new kernel I get:

Red Hat nash version 4.2.15 starting
Unable to find device-mapper major/minor
Reading all physical volumes. This may take a while...
No volume groups found
Unable to find volume group "VolGroup00"
ERROR: /bin/lvm exited abnormally with value 5 ! (pid 341)

I loaded all the settings in the Fedora kernel config to avoid problems like this, but obviously something is still wrong. I saw a bunch of errors when the config file was loaded, so that's probably the problem.

If I can't get this working with Fedora, can anyone recommend a distribution that's more "vanilla kernel friendly"? i.e. one that will boot if I copy the config it uses to the vanilla kernel.

Thanks,
Nick

Then donít use LVMs when you install FC4. LVMs are optional, unless you select autopartitioning.

FC4 didnít make it hard, you made it hard. Next time, manually partition during the installation and use conventional partitions.

That's nice.

In the meantime, would getting my current install to boot from a vanilla kernel require patching it with LVM support, or is there an easier way?

Did you enable Device Mapper Support when you compiled?

CONFIG_BLK_DEV_DM=m

Nick, I was just doing some testing on my system... same problem that you described.

I found this bug report posted on another forum:
https://bugzilla.redhat.com/bugzilla....cgi?id=169059

Seems to be related to mkinitrd... Long story short, I suspected that perhaps the kernel and mkinitrd get updated in the wrong order with yum, so what I did to fix was remove the latest kernel with:

yum remove kernel-2.6.14-1.1644_FC4

Then simply:

yum update OR

yum install kernel-2.6.14-1.1644_FC4

(to grab the latest kernel again)

Hope this at least gives you a clue (wasn't sure if you're custom compiling?)

Good luck!
