Fwd: Problems with numa



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 redhat com >

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?

kernel /vmlinuz-2.6.18-164.11.1.el5 ro root=LABEL=/ rhgb quiet crashkernel=128M 16M
