.... New to this list & definitely new to virtualization :-/ .... I am trying to setup a 64-bit CentOS 5.6 VM on a 64-bit FC14 server host, all patched up as of a couple of weeks ago. uname -a on the host shows: [wam at Q6600, CFD, 9:24:23am] 540 % uname -a Linux Q6600 2.6.35.11-83.fc14.x86_64 #1 SMP Mon Feb 7 07:06:44 UTC 2011 x86_64 x86_64 x86_64 GNU/Linux [wam at Q6600, CFD, 9:52:43am]

.... I have a 64-bit CentOS 5.6 VM running on a 64-bit FC14 host.

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... [root at seth ~]# fdisk -l Disco /dev/hdb: 40.0 GB, 40020664320 bytes 255 cabezas, 63 sectores/pista, 4865 cilindros Unidades = cilindros de 16065 * 512 = 8225280 bytes Disposit. Boot Start

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

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 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

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 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

Hello listmates, Here's I am, trying to install Centos 6.2 64-bit on a server with 24 TB of disk RAIDed as RAID 6. So I get this 18 TB disk (the RAID is recognized as one disk) where I am trying to put my OS. And I can create a couple of partitions - let us say I defiine a 150 GB swap, a 150 GB "/", a 100 GB "/var". So far so good. Then I try to define the next one, say, a

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

First I want to thank all of you who responded to me both on this list and in the CentOS wiki. Your responses helped greatly! I want to say that if you are running CentOS 5 and you do not have a overriding reason to go to CentOS 6, stay where you are. It was so much easier installing CentOS 6 on a new machine, migrating is next to impossible. Here's where I am today: 1. The base

Hi, I'm installing CentOS 4.4 64 bits with RAID 1 per software. But when the installation finishes, i cannot boot the system. I always get GRUB error 15. Any ideas ? Thanks in advance.

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

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 the new one

I have a p4 motherboard with 2 ide interfaces, I connect 2 40 GB drives as hda and hdc, I install Centos 4 from a CDROM, and partition the drives as 2 x raid partition each plus a swap partition on hda, the make md0 and md1 to install /boot and / respectively. Install goes well, everything looks great, go to reboot from drives, and all I get is "grub" but no boot. I have tried this ten
