Two CentOS installations failed dual boot
Hello everybody,
I installed Centos 6.2 on a computer with an older version of it in
order to dual boot both of them. I managed to install the new OS on a
physically seperated hard drive, and configured grub to make the newly
installed OS the default one. Now the older OS won't boot and this
error message shows: *"error 13: invalid or unsupported executable format"*.

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.*

Dual booting centos 4.1 and Solaris 10 express build 15
I have been trying to multiboot centos 4.1 and the
current solaris express build 15. I have two hard

FIXED Re: Re: MD Raid 1 software device not booting not even reaching grub
doing that grub-install /dev/sda will give me the "corresponding BIOS
device" error.
But now I fixed it by doing a manual grub install.
first boot with cd1 and type linux rescue at the prompt
when you're at the linux prompt after detecting and mounting the
partitions, do a "chroot /mnt/sysimage"
then
# grub --batch
#grub> root (hd0,0)

Problem with dual-booting soft-RAID
I set up IDE software-RAID on a test machine for testing the recover

the first disk, although grub etc. seems to be setup okay. Here's some
background:

GRUB woes: GRUB Hard Disk Error
Hello all,
I am attempting to install CentOS 5.5 on a recently donated home server (was
Windows). I've tried installing twice; first, separating /boot, swap, /,
/var, /usr and /home into different partitions, the second time choosing
default layout. Both times have resulted in "GRUB Hard Disk Error" upon
boot.
About the hard disk, it is a Seagate SATA drive. I do not have another

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.

CentOS 4 won't boot on test machine
I must have really shot myself in the foot on this one.
I reinstalled CentOS 4.4 (have to, for now) on my test machine,
exactly the way it was before (same options anyway), but when it comes
up, I get:

Problem with RAID on 6.3
I have 4 ST2000DL003-9VT166 (2Tbyte) disks in a RAID 5 array. Because
of the size I built them as a GPT partitioned disk. They were originally
built on a CentOS 5.x machine but more recently plugged into a CentOS
6.2 machine where they were detected just fine
e.g.
% parted /dev/sdj print
Model: ATA ST2000DL003-9VT1 (scsi)

Unknown boot option `pciback.hide=(09:04.0)': ignoring
Good morning,
I need to use pciback.hide to hide a pci card because I want to pci
passthrough that card to a domU. My hardware neither supports Intel-Vt-d
nor AMD's IOMMU. Unfortunately this doesn't seem to work in Centos 54
anymore. I guess it doesn't work because it is not compiled into the
kernel, but as a module. I got the following error in dmesg and the pci

Software RAID and GRUB on CentOS 7
Hi,
When I perform a software RAID 1 or RAID 5 installation on a LAN server
with several hard disks, I wonder if GRUB already gets installed on each
individual MBR, or if I have to do that manually. On CentOS 5.x and 6.x,
this had to be done like this:
# grub
grub> device (hd0) /dev/sda
grub> device (hd1) /dev/sdb
grub> root (hd0,0)
grub> setup (hd0)
grub> root (hd1,0)

Hi All,
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:
grub>root (hd0,0)
grub>setup (hd0)

Copying my system to another drive
Hi, I'm trying to copy my CentOS install to a new drive.
- old drive is /dev/hda and had
hda1 : /boot
hda2 : swap
hda3 lvm
hda5 : lvm
hda4 : /usr/local
- new drive is /dev/hdb
hdb1 : /boot
hdb2 : swap
hdb3 : /
I decided to get rid of lvm which is useless to me. I've created and
formated the new partitions and copied anything from the old drive to

how to cleanup old superblock
Hello!
Long time ago I created btrfs on /dev/sda
After some changes btrfs moved to /dev/sda1 (well, to md, and sda1 is
part of md).
As result, <btrfs fi show> show me 2 filesystems: new one and old one.
Probably I need to do some cleaning. Can someone tell me what to do.
