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

Hi all, I?m trying to create a RAID1 on a machine. I?ve already configurated BIOS (mother board, Intel, S500VSA SATA) so as to build RAID1 via hardware. However on CentOS Installer, when I reach "disk setup" screen, it shows up 2 devices (/dev/sda and /dev/sdb). Is this right (both devices being showed)? How should I proceed on this moment? If I create the

I have had great luck with nvidia fakeraid on RAID1, but I see there are preferences for software raid. I have very little hands on with full Linux software RAID and that was about 14 years ago. I am trying to determine which to use on a rebuild in a "standard" CentOS/Xen enviroment. It seems to me that while FakeRaid is/can be completely taken care of in dom0 dmraid whereas with

I have attempted to address all comments: http://wiki.centos.org/HowTos/SoftwareRAIDonCentOS5 Give me your best shot! :-D Phil

Does documentation exist describing how to convert a simple, single disk non-RAID CentOS 5 system to software RAID1 using the CentOS install CD/DVD as a rescue disk? (Assuming not) Is there a need for such? (Assuming need) I volunteer to produce it. -------------------- Ed Heron

When doing the 5.2 installation the ONLY drive option provided is mapper/nvidia_cbjcdhfe (250G) My system has 2 SATA - 250G drives and I want to use them in a RAID/LVM configuration. My question: How do I get the installer to let me use DiskDruid to create RAID1 arrays and then use LVM for the mount points? What I've done so far: I've verified that both drives are recognized by

Have a CentOS 4.x 32 bit server running on a single 500M SATA drive. What is easiest way to convert too RAID 1 on it? Anyone have a link? Would be open to hardware or software just do not want to reinstall the entire mess.

Hi A server has FakeRAID installed, I want to remove it to make it mdadm driven .... If I delete the FakeRAID including - disabling it in the BIOS - removing the dmraid driver from initrd - deleting all meta data from partitions - deleting all dmraid packages is the data still available on the drives, i.e. the partitions, filesystem and files are still ok? I know that FakeRAID controller

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

I need to do a new CentOS net install on a new server having the Supermicro X7DVL-3 motherboard: http://www.supermicro.com/products/motherboard/xeon1333/5000V/X7DVL-3.cfm Based on that info I assume the board having a "8x SAS Ports via LSI 1068E Controller". We received the server with 3 drives + 1 spare as hw RAID-5 preinstalled. During bootup I see that the drives are initialised

I have a new machine I'm trying to install Centos 5.0 on and I'm not getting very far. The system is 2 dual core xeons (5160, 3.0 GHZ) w/ 8GB ram. It has two 320 GB disks on the motherboard controller (Supermicro X7DAE+), and 8 750 GB disks on a 3ware 9650SE-8ml, pcie (x4) controller card. The 8 disks are set up as two raid 5 volumes (4 disks each). There is a scsi card in the machine

Hi list! I have a 3TB usb drive with an NTFS filesystem on it, that I can't mount.: [bent at bnlaptop ~]$ sudo /sbin/mount.ntfs-3g /dev/sdb1 /mnt Failed to read vcn 0xf28: Input/output error Failed to mount '/dev/sdb1': Input/output error NTFS is either inconsistent, or there is a hardware fault, or it's a SoftRAID/FakeRAID hardware. In the first case run chkdsk /f on Windows then

I've managed to install CentOS 5.1 on S5000PAL with fakeraid Intel Embedded Raid Technology II Raid1 (LSI chipset) with some help of kickstart declaration 'driverdisk --source=http://.../driver.img' Then I've had some problems with yum update - new kernel didn't know about megasr.ko. I've solved it with commands: cd /lib/modules/ cp 2.6.18-53.el5PAE/updates/megasr.ko

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

I have opened the case of the server and it's LSI card with FakeRaid !! What I have to do now as lspci shows it as intel cards?

Hello. I'm setting up a computer that will run 'CentOS 6 server'. The MB is an Asus with a hw raid controller (Promise PDC-20276), which I want to use in RAID-1 mode. I noted (from a MB website) that it also needs a driver - which is probably why it's called a 'fakeraid'. So, I've been trying to determine if any recent kernels support this chip. Using
