similar to: doing a new install on top of existing software raid-1

Has anybody encountered this problem? I have a box that has FC2 installed. I wanted to trash the FC2 installation and install CentOS 4. I have a pxeboot/dhcp/kickstart environment and so I tried automatic disk partitioning (clear all partitions and then create new ones), manual disk partitioning but everything else is automated and finally, zero automation, just a manual installation through

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>

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

Hello everyone. Is there possibility to install CenOS7 on LVM over software RAID? I wasn't able to do it... -- ???????? ??????

Hi all, Installing 5.5 on a fresh system having an Intel RAID. My 2 drives are configured as a mirror within the Intel BIOS. When starting my install, Anaconda throws an exception. After a brief goog, I see one possible fix is - at the install prompt, type; linux text nodmraid This is fine and all but Centos sees 2 disks at this point rather then 1 which is what I thought the Intel RAID

Hello... I have a server with 4 x SCSI drives and I would like to install Centos 4 (or 5) onto a software RAID 10 array. Do you know if this is possible? I noticed that under the Centos 4.92 beta, RAID 5 is an option but for some reason RAID 10 is not listed. There does appear to be a RAID 10 module.... /lib/modules/2.6.9-42.0.8.ELsmp/kernel/drivers/md/raid10.ko More info I found here:

Hi, I have a system with two IDE controllers running RAID1. As a test I powered down, removed one drive (hdc), and powered back up. System came up fine, so powered down installed a new drive (hdc) And powered back up. /proc/mdstat indicatd RAID1 active with hda only. I thought it would Auto add the new hdc drive... Also when I removed the new drive and added The original hdc, the swap partitions

I used Hiren Boot CD (Some tool on it) to create 8 partitions for Windows XP and CentOS 6. Now, CentOS6 Disk Utility reports for first partition: "Warning: The partition is misaligned by 512 bytes. This may result in very poor performances. Repartitioning is suggested.", and similar warnings almost all other partitions. Since I already have both Windows (NTFS) and CentOS 6

I am testing some kickstarts on ESXi virtual machine with pair of 16GB disks. Partitioning is lvm over raid. If i am using "logvol --grow i get "ValueError: not enough free space in volume group" Only workaround i can find is to add --maxsize=XXX where XXX is at least 640MB less than available. (10 extents or 320Mb per created logical volume) Following snippet is failing with

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

Does anyone know how anaconda partitioning enumerates disk partitions when specified in kickstart? I quickly browsed through the anaconda installer source on github but didn't see the relevant bits. I'm using the centOS 6.10 anaconda installer. Somehow I am ending up with my swap partition on sda1, /boot on sda2, and root on sda3. for $REASONS I want /boot to be the partition #1 (sda1)

I am mirroring two drives during install, what's the best practice here for the swap partition? Maybe two separate lv's from independent vg's *not* mirrored for swap and the let the OS manage it? Boot and the / vg will be mirrored. Thanks! jlc

Somewhere, mdadm is cacheing information.

I'm running Centos 6.5 on a software RAID-1 pair. I originally installed it following one of the howtos from the Centos WIKI for Centos 5. My first installation was on 5.x, then when I moved to 6.x I found that Anaconda worked enough like the one in 5.x that I could easily adapt the procedure. however, the new Anaconda is nothing like the old one, so I doubt the procedure could be made to
