I added "numa=off" on the kernel line in grub.conf. I am running
2.6.18-164.11.1.el5.
I renamed the executables for numactl so they could not be found.
/usr/bin/numactl-bad
/usr/bin/numademo-bad
/usr/bin/numastat-bad
I rebooted successfully, but the messages keep coming every two minutes.
I can't delete numactl.
rpm -e numactl
error: Failed dependencies:
libnuma.so.1 is needed by (installed) libvirt-0.6.3-20.1.el5_4.i386
[root@hurricane ~]#
I need email reports such as logwatch and our backup reports, so I
can't turn off
sendmail.
What other options are available?

Subject: Problems with numa - how to setup configuration options
Reply-To: General Red Hat Linux discussion list <redhat-list@xxxxxxxxxx

I have a system on which numa is running, but numa is not supported
by the hardware.
I am getting very frequent emails.
I understand that I I can turn numa off at the boot prompt by typing
in "numa=off"
I am not always at the system's console when I reboot the system and
I am not
the only person that may reboot the system. Is there a way I can
turn numa off
permanently?
Can I add "numa=off" to the end of the kernel line in /boot/grub/
grub.conf?
