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

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, 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

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

In the disk partitioner, I can't 1) choose to make the LVM with root and swap be on a RAID 1. Is there some way to do that, rather than two separate partitions RAIDed? 2) They don't align, so I can't clone /dev/sda to /dev/sdb as a failover (for /boot and /boot/efi). I've created those...

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?

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

Environment: CentOS 6.2 amd64 (min. server install) 2 virtual hard disks of 10GB each Linux KVM Following the instructions on CentOS Wiki <http://wiki.centos.org/HowTos/Install_On_Partitionable_RAID1> I installed a min. server in Linux KVM setup (script shown below) <script> #!/bin/bash nic_mac_addr0=00:07:43:53:2b:bb kvm \ -vga std \ -m 1024 \ -cpu core2duo \ -smp 2,cores=2 \

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

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

...s. Look at btrfs-progs (ctree.h:830): " /* * We don't want to overwrite 1M at the beginning of device, even though * there is our 1st superblock at 64k. Some possible reasons: * - the first 64k blank is useful for some boot loader/manager * - the first 1M could be scratched by buggy partitioner or somesuch */ #define BTRFS_BLOCK_RESERVED_1M_FOR_SUPER ((u64)1024 * 1024) " 1MiB seems to be a reasonable size to fit bootsector + LDLINUX.SYS in. I don't know exactly how Syslinux is handling this, but it should be using the whole available space (1MiB instead). -- Paulo Alcantara,...

Oh, Boy. I am in trouble now.... I just installed Centos on a USB drive on my corp notebook. To not TOUCH my corp drive. I spent time with the drive partitioner to make sure that nothing was done to the internal hard drive... Well I missed something and I overwrote the encrypted bootloader on the hard drive. Now what? Can I rescue things? I am leaving for my flight in a couple hours to Dublin for IETF meeting. I have to get this working on my own....

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

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

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

The EL7 partitioner is a complete disaster and I regularly bitch about it on twitter and irc. You could try to convince it with kickstart and bypass the GUI altogether. Another option is to boot in a Live CD and do you partitioning from there either manually or via Gparted and hope these changes will be picked up by t...

Hello List, i try to install Centos 6 on a Server with 2x 3TB Disks. When anaconda is showing up the disk partitioner i cant do more then 3 "normal Partitions" or more then 3 "Raid Partitions". Even when u choose that each partition is 200mb, u cant do more then 3 "normal" or "raid" partitions. is this a bug of anaconda installer? thanks marko

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
