similar to: Booting CentOS 5.5 (KVM) from a second disk

Hi all! Doing some tests with CentOS 5.5 on a KVM virtual machine, after doing the installation, I added a second disk. But when trying to boot from it, I get the following error: --------------------------------------------------------------------- root (hd1,0) Error 21: Selected disk does not exist --------------------------------------------------------------------- The two disks are

Hi all, I've installed CentOS 4.4 in a box which previously had dual boot (XP SP2 and Ubuntu) I can run CentOS without problem but I can't boot XP SP2. When I try it the system simply hangs...

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) Filesystem type is ext2fs,

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.* # mdadm /dev/md0 --add /dev/sdb1 # mdadm /dev/md1 --add /dev/sdb2 # mdadm /dev/md2 --add /dev/sdb3 # mdadm

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

Hi..... I just bought a External HD with USB/FireWire interfaces. I was trying to connect it by firewire and nothing happened, but it's connected by USB, there is no problem. This is the "fdisk - l" output when i connect it by USB Disco /dev/sdc: 160.0 GB, 160041885696 bytes 255 cabezas, 63 sectores/pista, 19457 cilindros Unidades = cilindros de 16065 * 512 = 8225280 bytes

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

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"*. I attached

Hello Everyone I have a remote CentOS 6.4 server (with KVM access), when I received the server it was running with LVM on single disk (sda) I managed to remove LVM and install raid 1 in sda and sdb disks the mirroring is working fine, my only issue now is that everytime I reboot the server I got the grub command line and I have manually boot using comand grub> configfile

I have been trying to multiboot centos 4.1 and the current solaris express build 15. I have two hard drive s, the first one ( hd0 ) devoted to CentOS 4.1 and windows xp (no problems). The second drive (hd1) for Solaris 10 only. I tried to boot solaris from CentOS grub and got the following error messages: Booting Solaris 10 root(hd1,0) Filesystem type unknown, partition type 0Xbf kernel

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

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... Everything is running fine but

I set up IDE software-RAID on a test machine for testing the recover functionality. The problem is that it somehow won't boot after removing the first disk, although grub etc. seems to be setup okay. Here's some background: 2 disks hda and hdb RAID 1 setup: /dev/md0 (hda1 + hdb1) /boot /dev/md1 (hda2 + hdb2) / /dev/md2 (hda3 + hdb3) swap done with disk druid during initial setup from

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

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: 1. Build a 100MB RAID-type partition on each

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: Booting 'CentOS-4 x86_64 (2.6.9-42.ELsmp)' root(hd1,0) Filesystem type is ext2fs, partition type 0x83 kernel /vmlinuz-2.6.9-42.ELsmp ro root=LABEL=/ rhgb quiet Error 15: File not

I've got two pendrives. I want to install a Debian on them. RAID1. Ok... ... After I installed it in RAID1, it works perfectly, ok! :) When I pull out one of the pendrive [good pendrive], it still boots up, hurrah :) But: ... When I pull out the other pendrive [i plug in the first one i tried] it say's: GRUB hard disk error What can I do? I already tried: grub-install /dev/sdc

This completes the switch to ext3 backed root partitions. /boot is now contained on each Root/RootBackup partition. On install grub is updated to read and boot from the correct partition as well. --- scripts/ovirt-config-boot | 29 ++++++++++++------------ scripts/ovirt-config-storage | 47 +++++++++++---------------------------- scripts/ovirt-config-uninstall | 5 +---
