Software RAID + LVM + Grub
I'm playing with software RAID and LVM in some virtual machines and
I've run into an issue that I can't find a good answer to in the docs.
I have the following RAID setup:
md0: sda1 and sdb1, RAID 1. This is /boot
md1: sda2 and sdb2, RAID 1. This is a PV for LVM.
VolGroup00, this is the volume group and md1 is the only PV in it.
LogVol00 is swap
LogVol01 is /
LogVol02 is /home

Centos 5.5, not booting latest kernel but older one instead
I've been going along not noticing things happening right under my nose.
so imagine my surprise when I discovered last night that my Centos 5 box
has installed multiple new kernels over the last few months, as updates
come out, and IT IS NOT BOOTING THE NEWST ONE.
grub.conf says to boot kernel 0, and 0 is the newest one. but the one it
actually boots is 6 or 8 down the list (clearly I've

CentOS 5.7 gives me a blank screen after bootup
Hi all,
I have an odd problem, for which I couldn't find any suggestions on google.
A CentOS 5.7x64 gives me a blank screen on bootup, both to the 17" LCD
monitor connected to the VGA port, and to the KVMOVIP device
built-into the server,
I can see the GRUB boot loader, and everything booting up, upto the
point where it says "Waiting for driver initialization.", then it goes

system "stuck" with 2.6.18-128 kernel. how to move to 2.6.18-194.17?
Hi. I just noticed I had a CentOS 5.3 system that I updated to CentOS
5.5 a few days ago,
and I just ran "yum -y update" again to get the latest kernel, and I
just noticed it still has the old 2.6.18-128 kernel instead of the new
2.6.18-194.17. What gives?
/etc/grub.conf points at 2.6.18-194.17, but when I reboot, 2.6.18-128 comes up.
Any suggestions?
Thanks,

I'm currently trying to install centos 5.4 x86-64bit on a raid 1, so if one the 2 disks fails the server will still be available.
i installed grub on /dev/sda using the advanced grub configuration option during the install.
after the install is done i boot in linux rescue mode , chroot the filesystem and copy grub to both drives using:

boot problem after disk change on raid1
Hello,
I have two disks sda and sdb. One of the was broken so I have changed the
broken disk with a working one. I started the server in rescue mode, and
created the partional table, and added all the partitions to the software
raid.
*I have added the partitions to the RAID, and reboot.*

Invalid or unsupported executable format, or is it a reiserfs problem?
Our newly build xen kernel does not boot. The error message is : Invalid
or unsupported executable format.
I have build xen from the xen-2.0.4 source (make world, make install) on
a debian sarge system.
I have not changed any of the kernel configurations, I did make an
initrd image.
The entry in my menu.lst is :

Turning root partition into a RAID array
I have a CentOS 4.2 system that was set up VERY quickly following the demise
of its former life as a CentOS 3 server - you don't want the full story, but
it had to be done quickly to get a company up and working following a slight
disaster involving an electrician, a portable appliance safety tester and a
pulled power cable - anyway, here's where I am at...

Changing booted Kernel with grub
Hi,
I have updated the kernel to 2.4.21-27.0.2 on Centos 3.4 (was 3.3 when
I did the kernel update) and have modified grub.conf to use the single
CPU kernel:
# grub.conf generated by anaconda
#
# Note that you do not have to rerun grub after making changes to this file
# NOTICE: You have a /boot partition. This means that
# all kernel and initrd paths are relative to /boot/, eg.

Problem getting x86_64 dom0 to boot on a FC4 machine
I''m struggling to get Xen to boot on a FC4 Opteron box. I''ve included the
tail of the boot log below [1]. I suspect that the problems relates to the
software RAID 1 root and boot partitions, and how it relates to the initrd
image. The RAID volumes fail to mount.
I compiled the Xen snapshot from the 23rd September, and the only change
I''ve made is to enable the

Xen Installation problems
Hello Xen Users,
I am facing a problem getting my installation of XEN boot up on a Red
Hat Linux Guest OS. What''s happening is that the grub loader tries to
install Xen but after a while it crashes and starts rebooting
recursively. I have tried both the entries listed below. I am using the
following entries in the grub.conf file:

UP vs SMP kernel ?
There was a discussion here several days ago that was precipitated by my
decision to manually install the new kernel before YUMming the upgrade
to CentOS 4.2. The upgrade went south but I recovered by doing a fresh
install and a bunch of copying from backups. All's well EXCEPT that I'm
back in the same "box", thanks to anaconda.
I set out to upgrade kernels this morning:

question on software raid-1
I have a system that is RAID -1 configured as
/dev/md0 is /dev/hda1 /dev/hdb1
/dev/md1 is /dev/hdb3 /dev/hdb3
it seems as though /dev/hda has failed....
I have another disk (identical model) that I can replace hda with.
I know about the commands fdisk to repartion and raidhotadd /dev/md0
/dev/hda1
and raidhotadd /dev/md1 /dev/hda3 (to be ran after the system boots).
BUT... how do I now get
