  • Red Hat Enterprise Linux システムで NUMA を無効にする方法は?


ブートローダー設定のカーネルコマンドラインに「numa=off」を追加してシステムを再起動すると、NUMA が無効になります。


  • RHEL 4、RHEL 5、RHEL 6 (/boot/grub/grub.conf)
    title Red Hat Enterprise Linux AS (2.6.9-55.EL)
            root (hd0,0)
            kernel /vmlinuz-2.6.9-55.EL ro root=/dev/VolGroup00/LogVol00 rhgb quiet numa=off
            initrd /initrd-2.6.9-55.EL.img
  • RHEL 7 (/etc/default/grub)
    GRUB_CMDLINE_LINUX=" vconsole.font=latarcyrheb-sun16 crashkernel=auto  vconsole.keymap=us rhgb quiet numa=off"

RHEL 7 で変更を有効にするには、grub 設定を再ビルドする必要がある点に注意してください。

~]# grub2-mkconfig -o /etc/grub2.cfg
