similar to: Centos 4.2 and Boot/Root on RAID?

I'm just about to build a new server and I'm looking for recommendations on what hardware to use. I'm happy with either a brand name, or building my own, but would like a hardware RAID controller to run a pair of disks as RAID1 that is actually compatible with and manageable through Linux. Any recommendations would be appreciated. Gary

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

I installed Centos 6.x 64 bit with the minimal ISO and used two disks in RAID 1 array.

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've just finished installing a new Bacula storeage server. Prior to doing the install I did some research and ended up deciding to do the following config. 6x4TB drives /boot/efi efi_fs sda1 /boot/efi_copy efi_fs sdb1 /boot xfs RAID1 sda2 sdb2 VG RAID6 all drives containing SWAP / /home /var/bacula Questions: 1) The big problem with this is that it is dependant on sda for

I''m currently researching an upgrade to (raid1-ed) btrfs from mostly reiserfs (which I''ve found quite reliable (even thru a period of bad ram and resulting system crashes) since data=ordered went in with 2.6.16 or whatever it was. (Thanks, Chris! =:^)) on multiple md/raid-1s. I have some questions that don''t appear to be addressed well on the wiki, yet, or where

CentOS Community, I have a dedicated server with 4 hard drives in a RAID 10 software configuration running LVM. My OS is CentOS 6.2. Earlier today, I rebooted my system and my system did not come back online. I opened a ticket with my datacenter who informed me that one of my hard drives is no longer recognized by the bios and has failed. I was told that an OS reinstall was needed. I

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 have CentOS 4.x installed on a single 500GB SATA drive. Drive is about 10 percent used. I would like to migrate to software RAID 5 without reinstalling the OS. Was thinking 3 500GB drives. Is that possible or must I reinstall? Matt

Hi, I have a new server HP proliant DL320 G4, with two 160 GB SATA hdds.. I have installed CentOS 4.5 with mdadm without any problem, but when I disconnect one disk the server does not boot or I received a kernel panic when booting... I have disabled the SATA embeded raid (BIOS) and nothing.. I've also download the driver from HP site HP (Embedded SATA RAID Controller Driver Diskette for Red

Hi, I had this hard time installing a server with RAID 1 by software. I always got an error from GRUB and no booting. So, i've installed CentOS 4.4 normally in only one disk. Question is: is it possible now to make a RAID 1 by software with the other disk ? If so, how ? I'm completely lost here. Any help would be appreciated.

Hello. I am trying to boot CentOS 4 from a copy of an ext3 software RAID 1 filesystem (md) which has been copied to a normal ext3 filesystem (hd). I am almost getting there, exept that the system hangs after booting the kernel. I copied the datas from the /boot and / partitions to two similar partitions on the backuped disk with mirrordir (can also be done with cp or dd). I have setup the new

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

I have a new server to setup. 4 hard drives and I had intended it to be hardware raid but that's a long story. Does it make sense to set up the first two hard drives with RAID-0 partitions and then get through the install and then go back later and then create identically sized RAID-0 partitions on the other two drives and finally create the RAID-1 mirror from the first to the second? Craig

Hi all, I discovered lately that two of my XEN servers suffer from a really bad disk throughput - in domU as well as in dom0. All of them run Debian/Etch, Kernel 2.6.18-6-xen (orig. Debian) with XEN 3.2 (backported). The software versions seem to be ok for most machines: Lenovo A57 with S-ATA and (E8200, VT enabled): up to 90MB/s Shuttle, FB61 based, ATA-Disk (Celeron, no VT): up to

I think I have solved my issue and would like some input from anyone who has done this for pitfalls, errors, or if I am just wrong. Centos 5.x, software raid, 250gb drives. 2 drives in mirror, one spare. All same size. 2 devices in the mirror, one boot (about 100MB), one that fills the rest of disk and contains LVM partitions. I was thinking of taking out the spare and adding a 500gb drive. I

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
