Re: How to Increase VmallocTotal

This is defined in kernel code. there was a  a way to do it from the command line too.
*vmalloc=<size>* You may try this command line option at boot time.

Hello,
 
I am using a RedHat Enterprise WS v4 distribution.
 
I am looking to increase the value that is displayed by VmallocTotal using `cat /proc/meminfo`. The value I currently have is "VmallocTotal:   106488 kB". This is unacceptable for the current situation.
 
On another system using a Fedora Core 3 distribution, the VmallocTotal value is "VmallocTotal:  3612664 kB". This is what I want.
 
Both systems have 1GB RAM installed. The hardware is identical. The distributions are the difference.
 
I have attempted to follow the definition of VMALLOC_START to ascertain if I could adjust it to get the VmallocTotal to the value I want. I have been unsuccessful down this path.
 
I am looking for a system utility or something to configure to allow the RHEL 4 system to increase its vmalloc space. I would prefer not to have to recompile the kernel for this to work.
 
 
Thank you for your help.
 
Bill
