Hi, I've written two small howtos, and would like to contribute them to the CentOS Wiki. The first one is "How to install CentOS 5 on software partitionable mdadm RAID1", and the second one "How to repair a software mdadm RAID5 with two or more failed disks (if you know that information is still on the disks and readable)". I think that the first one should be somewhere

Hi, After reading the tutorial at http://wiki.centos.org/HowTos/Install_On_Partitionable_RAID1 I have the following question: What should I put instead of splashimage=(hd0,0)/grub/splash.xpm.gz and root (hd0,0) on /etc/grub.conf? Should I leave those lines untouched? If so, how would grub know where to boot from if /dev/sda fails? Or I would need to swap the drives in order to boot

Hello all, I'm trying to install CentOS 6.3 to an mdadm partitionable array and not having any luck. The installer only allows me to create one file system per md device, or specify the md device as a LVM physical volume. I don't want to do either, I want to create one md device and create multiple partitions on top of the md device. I thought that perhaps the installer was preventing

Hi. The following HowTo on the CentOS Wiki: http://wiki.centos.org/HowTos/Install_On_Partitionable_RAID1 valid for CentOS 5, has not been updated to CentOS 6, yet. I found it very useful during the glorious CentOS 5 days and now that I've successfully ported my RAID1 experience to CentOS 6, I'd like to share it with the Community. The title of the HowTo is currently: "How to

Greetings - I am preparing to order a new desktop system for work. In general the new system will be a Dell Precision T3610 with two 3 TB drives. I plan on installing CentOS 7 as a KVM host, with virtual machines for Win 7 Pro and Linux Mint. I am looking for some advice or a good how-to on configuring software raid on the two drives, then using LVM for the host and virtual machines. I

I have some suggested tweaks and changes to http://wiki.centos.org/HowTos/Install_On_Partitionable_RAID1 1. The user should be instructed to start rescue mode with networking in order to be able to retrieve the patch for mkinitrd. 2. The command to create /etc/mdadm.conf will result in an extra line "spares=1" while the array is still syncing. Adding " | head -1 " to the

Hi! Did anyone tried this on 5.4? having a look on http://wiki.centos.org/HowTos/Install_On_Partitionable_RAID1 is would seem that that mkinitrd patch is no longer required. Can someone ack this?

dear All, I'm spending the afternoon trying to build software raid using this ( excellent ) guide : http://wiki.centos.org/HowTos/Install_On_Partitionable_RAID1 I'm doing this not only because this machine has no raid controller - I could go out and buy one - but also because I hope software raid will provide easier monitoring. This is a newly installed, updated Centos6.4 standard

Hello Since linux 2.6, the md layer has a feature called partitionable arrays. So instead of having two disks, creating an identical partition table on both and then putting those partitions in RAID 1, you take those two disks and put them in one partitionable RAID 1 array (in mdadm terms, "mdp") and create a partition table on the new RAID device. The advantages are quite clear

Hi all! I'm building up a new box and plan to use Centos 5 on it. i've got a pair of SATA 320 GB drives to make a RAID1. I'm trying to follow the "howto" on the centos wiki for making a "partitionable RAID" installation. Given that my partition scheme has a separate /boot partition, while the one in the HOWTO apparently does not, I've had to tweak the steps

So, it installed happily. Then wouldn't boot. No problem, I'll bring it up with pxe, then chroot and grub2-install. Um, nope. I edited the device map from hd0 and hd1 being the RAID to /dev/sda and /dev/sdb, then ran grup2-install. It now tells me can't identify the filesystem on hd0, and can't perform a safety check, and gives up. What am I missing? Google is not giving me any

Arch = x86_64 CentOS-6.4 We have a cold server with 32Gb RAM and 8 x 3TB SATA drives mounted in hotswap cells. The intended purpose of this system is as an ERP application and DBMS host. The ERP application will likely eventually have web access but at the moment only dedicated client applications can connect to it. I am researching how to best set this system up for use as a production host

Hi all, I was recently charged with configuring a new fairly large (24x3TB disks) fileserver for my group. I think I know mostly what I want to do with it, but I did have two questions, at least one of which is directly related to CentOS. 1) The controller node has two 90GB SSDs that I plan to use as a bootable RAID1 system disk. What is the preferred method for laying out the RAID array? I

Trying to install Centos6 on my system (it's been running C5 for years). I've got a pair of drives, so I'm trying to use RAID-1. Previously I used a procedure where each partition was part of a separate RAID device, but this time I'm trying the HOWTO from the Centos WIKI on making a partitionable RAID pair. I've been having a lot of problems, but have also been working thru

I have been reading about software raid. I configured my first software raid system about a month ago. I have 4 500 Gig drives configured in RAID 5 configuration with a total of 1.5TB. Currently I configured the complete individual drivers as software raid, then created a /dev/md0 with the drives I then created a /file_storage partition on /dev/md0. I created my /boot / and swap partitions on
