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, 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

On the wiki page for creating a mirrored root drive, at <https://wiki.centos.org/HowTos/Install_On_Partitionable_RAID1>, it first tells you, in the install, to chose manual partitioning, and to leave at least 1M at the end of the drive.... and then it tells you to create the RAID 1 using /dev/sda and /dev/sdb - the *whole* raw drives. mark, currently creating a RAID 1 using just

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

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 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

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. 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

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

I am running software RAID1 on a somewhat critical server. Today I noticed one drive is giving errors. Good thing I had RAID. I planned on upgrading this server in next month or so. Just wandering if there was an easy way to fix this to avoid rushing the upgrade? Having a single drive is slowing down reads as well, I think. Thanks.

I just installed CentOS 5.4 64 bit release on a 1.9ghz CPU with 8gB of RAM. It has 2 Western Digital 1.5TB SATA2 drives in RAID1.

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

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 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

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
