Booting CentOS 5.5 (KVM) from a second disk

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.*

Install Problems Centos 4.1
Dear All,
I have a K8S-MX Asus Athlon 64 Motherboard with a 754 pin 3000+ CPU,
which I cam trying to install 4.1 Centos 64 bit.
The problem seems to arise when installing onto Mirrored disks, I have
noticed that from Centos 4 onwards it tries to rebuild the arrays as it
installs which slows the whole process right down across all platforms I
have tried it on.
In addition, the install

I'm going to guess that there are no IDE drives that have 4096 byte
physical sectors, but it's worth confirming you don't have such a
drive because the current partition scheme you've posted would be
sub-optimal if it does have 4096

Is that true? If I have a system with two disks, where device.map
labels one as hd0 and the other as hd1, and I swap those numbers, the
resulting boot sector will differ by one bit.

4.2 install w/250GB raid arrays won't boot
hi!
raid 1 arrays: I already have 2 systems running this same raid1 config.
1 sys has 2 120 gb
1 sys has 1 120gb and 1 200gb but matching the raid partitions
this system here that is giving me fits right now has 1 250gb and 1
200gb. I tried it w/a new 250 gb for the 2nd drive but the same
results. Will not boot.
in druid, when I am config. the raid arrays, I always create the
boot partitions

CentOS 5 grub boot problem
I never thought I'd say this, but I think it's easier to do this with
GRUB 2. Anyway I did an installation to raid1's in CentOS 6's
installer, which still uses GRUB legacy. I tested removing each of the
two devices and it still boots. These are the commands in its log:
: Running... ['/sbin/grub-install', '--just-copy']
: Running... ['/sbin/grub',

CentOS 5 grub boot problem
I am trying to upgrade my system from 500GB drives to 1TB. I was able
to partition and sync the raid devices, but I cannot get the new drive
to boot.
This is an old system with only IDE ports. There is an added Highpoint
raid card which is used only for the two extra IDE ports. I have
upgraded it with a 1TB SATA drive and an IDE-SATA adapter. I did not
have any problems with the system

Boot from degraded sw RAID 1
OK, this is probably long, and your answer will surely make me slap my
forehead really hard... please help me understand what goes on.
I intend to install CentOS 5.1 afresh over software RAID level 1. SATA
drives are in AHCI mode.
I follow basically [1] though I have made some mistakes as will be
explained. AFAIK GRUB does not boot off LVM, so I:
