I discovered that some of my servers weren't seeing all the installed
ram under RH8. In the documentation I found the reference to mem= for
the grub.conf file. I updated my grub.conf file to look like this:
title Red Hat Linux (2.4.20-28.8smp)
root (hd0,0)
kernel /vmlinuz-2.4.20-28.8smp ro root=LABEL=/ mem=2000M
initrd /initrd-2.4.20-28.8smp.img
title Red Hat Linux (2.4.20-28.8)
root (hd0,0)
kernel /vmlinuz-2.4.20-28.8 ro root=LABEL=/
initrd /initrd-2.4.20-28.8.img
title Red Hat Linux (2.4.20-24.8smp)
root (hd0,0)
kernel /vmlinuz-2.4.20-24.8smp ro root=LABEL=/ mem=2000M
initrd /initrd-2.4.20-24.8smp.img
When I boot to 2.4.20-24.8smp, linux sees all the memory. When I boot
to 2.4.20-28.8smp, it doesn't. It's as if the mem statement is ignored
for the 28.8smp version. I also tried using mem=2097088K, but that
didn't help.
Any ideas? Thanks.
Jon
