similar to: MIrrored drives won't boot after installation

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

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

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

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',

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

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.

I am using Xen 3.3 from source. My PV guest boots fine with the normal kernel and initrd options When I boot the guest with PV GRUB I only get: GNU GRUB version 0.97 (65536K lower / 0K upper memory) [ Minimal BASH-like line editing is supported. For the first word, TAB lists possible command completions. Anywhere else TAB lists the possible

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)

Hi, I use Centos 5.4 x86_64 kernel used is 2.6.18-164.11.1.el5xen I have a physical machine running Debian Etch (32 bit) and Debian Lenny and I virtualized the first one as follows: *Created a HVM DomU with Virt-Manager with a virtual disk file of 40000 M *Boot from LiveCD, and created a swap and a ext3 partitions (Yes, very simple layout). *Rsync'd files from root partition of physical

Hi folks PV-GRUB built from Xen 3.3.0 is not able to read from devices without a partition table: | grubdom> root (hd0) | Filesystem type unknown, using whole disk Part of the config: | disk = [ "phy:vg0_sledgehammer/servext_root,xvda,w" ] Device: | # file -s /dev/vg0_sledgehammer/servext_root | /dev/vg0_sledgehammer/servext_root: symbolic link to

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

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>

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

Trying a different approch. Senario Raid 1 setup Bootable raid drive failed Mirror has been working for almost a month and then rebooted Now can't boot mirror drive grub not mirrored from other drive. I Fixed bootable drive. Question? Can I hook up both drives and boot fixed drive then rebuilt mirror from nonbootable drive to bootable drive? Does the raid automatically rebuilt when I

I''ve got knee deep into learning how to use Opensolaris and zfs, and I see now that my goal of home zfs server may have been better served if I had partitioned the install disk leaving some of the 60GB to be added to a zpool. First, how much space does a working OS need. I don''t mean bare minimum but to be comfortable and have some growing room (on the install disk)?

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.

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
