RE: Why does old kernel boot when new kernel installed?


Yes - verified with uname -a

Our tech support are Linux/UNIX professionals & are baffled - I am hoping
for some help here, I am emailing as they don't have the time, look after
over 100 servers, we only run 12 so I try to dig ....

Apologies if trivial & timewasting but important for us - surely someone can
tell me why GRUB only shows the single kernel when 3 are there?

Last night I did kernel upgrades of 3 other machines & all went through just
fine ..... only this 1 machine has this problem?

In answer - only 1 grub.conf

[root ns5 nico]# whereis grub.conf
grub: /sbin/grub /etc/grub.conf /usr/share/grub
[root ns5 nico]#

Any help would still be very much appreciated.

Possibly because grub uses a different grub.conf than you think?

At this stage I'd recommend to get a Linux/Unix professional as this
seems to be standard stuff that you should know how to do and if you
don't, then leave it alone and let it do someone, who knows what he does.
Sorry if that sounds a bit harsh, but it looks like you are wasting the
valuable time of the developers with trivias.

Have you actually verified with 'uname -a' that this old kernel is running?
