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

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

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

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)

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

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, After rebooting my CentOS 5.5 server, i have the following message: ================================== Red Hat nash version 5.1.19.6 starting EXT3-fs: unable to read superblock mount: error mounting /dev/root on /sysroot as ext3: invalid argument setuproot: moving /root failed: No such file or directory setuproot: error mounting /proc: No such file or directory setuproot: error mounting

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) grub>

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, -at myserver# yum -y

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,

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'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

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

So I'm trying to RAID-1 this system which has two identical disks installed in it, and it isn't working for some reason. I started by doing a CentOS-4 install on /dev/sda1 as root, and with /dev/sda2 as my swap. I finish the install, yum update, and then I want to make the mirrors. I copy the partition table from one disk to the other: # sfdisk -d /dev/sda | sfdisk /dev/sdb I create

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 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

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
