Re: mkinitrd error

[Arthur Perry]

Hi Steve,

You probably want to communicate this back to RedHat. (I assume you are
using RedHat)..
I have seen the same thing, but honestly did not take it too seriously.
I figured someone else would report it to them ;)

The mkinitrd script is located at /sbin/mkinitrd.
It creates a fixed-size ramdisk at 4000 kbytes if i386, and 8000 kbytes
for "all" other architectures (or more accurately, other architectures
that would see this specific script) .. That would be ia64.
For a quick fix, you can change this value to something larger like 12000.
This should fit what you need.
Just change line 45 from "IMAGESIZE=8000" to "IMAGESIZE=12000".
You now can re-run it and it should complete without errors.

Then you will need to modify your elilo.conf file, passing the new
ramdisk size to the kernel command line.
This has to be done because the new ramdisk size is larger than the
default value which the kernel expects.

Simply find your active kernel paragraph in the
/boot/efi/efi/redhat/elilo.conf file, and make sure your append line
reads,
append="root=LABEL=/ ramdisk_size=12000"

Off the top of my head, I think this is all you need to do.

FYI, correct me if I am wrong everyone, but this really should go to a
RedHat support mail group. Not the kernel development one.
It was just a free ticket and I am just having my morning coffee ;)
