Turning root partition into a RAID array
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

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

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',

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) Filesystem type is ext2fs,

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

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

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.

Centos 5.5 KVM GRUB / Virtio issue
I have a virtual machine that had been running fine using a RAW disk image (IDE). I am in the process of converting this virtual machine to use a single LVM and virtio. (For LVM backup snapshots and easy resizing purposes (no LVM within the guest)) I create the LVM and copied all the files from the existing RAW image to an ext3 under the LVM. However, I cannot get it to boot. It has to do

ZFS Boot Won''t work with a straight or mirror zfsroot
Using build 70, I followed the zfsboot instructions at http:// www.opensolaris.org/os/community/zfs/boot/zfsboot-manual/ to the letter. I tried first with a mirror zfsroot, when I try to boot to zfsboot the screen is flooded with "init(1M) exited on fatal signal 9" Than I tried with a simple zfs pool (not mirrored) and it just reboots right away. If I try to setup grub
