similar to: Installing on partitionable RAID arrays

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 All, I am trying to create an MD device. I am using the command: /sbin/mdadm --create --a /dev/md12 --level=1 --run --raid-devices=2 /dev/sda12 /dev/sdb12 to create the device, and to dynamically create the device file if needed. What I want is the device file to be created as /dev/md12, but with the -a flag it creates it as /dev/md<first unwsed minor number>. I have tried various

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

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

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

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

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 all, I'm having quite an interesting time getting up to speed with KVM/QEMU and the various ways of creating virtual Guest VMs. But disk I/O performance remains a bit of a question mark for me. I'm looking for suggestions and opinions .... This new machine has tons of disk space, lots of CPU cores and loads of RAM, so those are not issues. I currently have several software

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

Hello. I just tried (as my first attempt in xenning) to set up a lenny amd64 domU on a partitionable Mirror RAID (/dev/md_d0p1 - /dev/md_d0p4), using the Debian installer from "people.debian.org/~joeyh/d-i/images/daily/". The partitions of the md will be represented inside the domU as /dev/xvda1-4 accordingly. The dom0 seems to run fine, it''s Xen 3.2.1 on amd64 lenny. The

Hello folks, I am experiencing a weird problem at bootup with large RAID-6 arrays. After Googling around (a lot) I find that others are having the same issues with CentOS/RHEL/Ubuntu/whatever. In my case it's Scientific Linux-6 which should behave the same way as CentOS-6. I had the same problem with the RHEL-6 evaluation version. I'm posting this question to the SL mailing list

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

Hi messmer, seems that anaconda supports partitioned RAID devices. Disk selection see one mdraid device and permits to create partition on it.

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
