CentOS 5 Hardware :: Error Installing CentOS 5.2 On ICH7R With 4 SATA HDDs RAID 5?

Feb 15, 2009

The installer can't see my raid controller (I assume) as I'm getting the following error:"Error opening /dev/mapper/isw_jbhgjgjj_Vol0: No such device or address"It just sees them as 4 individual drives: sda, sdb, sdc and sdd.Please note that I have set up the RAID 5 in the controller bios interface and the image name is Vol0, which it seems that it tries to load but for some particular reason it can't.I have also tried different bios settings and nothing worked.

CentOS 5 Hardware :: Installing CentOS 5.4 X86_64 On Adaptec RAID 3405

Jan 13, 2010

My problem is that I'm trying to install CentOS 5.4 x86_64 DVD ISO on Supermicro X7SBI server with installed Adaptec RAID 3405 controller.

I created RAID 5 array and is working fine (adaptec status says Optimal) but I can't install CentOS to that array (1.5TB size).

Whenever I try to install with: linux dd

I'm asked for a driver, which I have downloaded from Adaptec site and extracted contents to USB drive (in installation found as /sba1) which has now a lot of IMG and some ISO files on it.

I try to load (I simplified names) RHEL5.img, CENTOS.img... with x64 names (one exact name: aacraid driverdisk-CentOS-x86_64.img) and I always get the error message: "No devices of the appropriate type were found on this driver disk"

This is going on for a week now and I can't find the right driver or something I'm doing wrong to get install done.

CentOS 5 Hardware :: Installing Centos 5 On HP DL380R05 E5420 With RAID-1?

May 7, 2009

I need your help urgently. I will shortly install Centos 5 on a HP DL380R05 E5420 Server with two HP 146GB 10k 2.5 SAS HP SP hard disks running hardware RAID-1. I am a newbie on CentOS, please advise me:

1. Do I need a Centos RAID device driver for hardware RAID-1 on the HP DL380R05 E5420 Server?
2. Should I use Centos i386 or Centos x86_64 in this case? Which one: CentOS 5.2 or CentOS 5.3?
3. Does Centos support Embedded NC373i Multifunction Gigabit network cards?

The following is my server's hardware configuration:

HP DL380R05 E5420 2GB Base AP Server(1) Quad-Core Intel Xeon Processor E5420 Two Embedded NC373i Multifunction Gigabit / 2 GB (2 x 1 GB) PC2-5300 Fully Buffered DIMMs (DDR2-667)/HP Smart Array P400/256MB Controller /Rack (2U)/Hot Plug Fully Redundant Fans Standard Two HP 146GB 10k 2.5 SAS HP SP HDD HP 1000W IEC C14 Cord RPS Kit

CentOS 5 :: Installing 5.2 On RAID Over 2 TB?

Mar 9, 2009

I tried install Centos 5.2 (i386) on Dell PowerEge 2950 server with SAS RAID disk (RAID 5 on PERC 6/i created from six HDD, 1 TB each). I never installed Centos on a disk over 2 TB.
I find out that i need use gpt instead mbr. I tried use rescue mode + parted but after rebooting I got message "Can't boot from from GPT partition" whet tried install. But when the space is partitioned by installer, I can't boot up.I got msg PBR not found. My ask is: "Can I boot directly from GPT partition? If yes how do it?" Or even better "How to install centos 5.2 on disk bigger than 2 TB?"

CentOS 5 :: Installing The SATA RAID Controller?

Mar 19, 2009

I'm working on a new server and it has an Nvidia SATA array controller with 2 250Gb SATA drives configured in a hardware array. When the first screen comes up I'm entering the option Linux DD for it to prompt me for the drivers but nothing ever happens. The screen says that it's loading a SATA driver for about 15 minutes and then the screen clears and has a plus sign cursor on a black screen. What am I doing wrong? The only driver that came with the HP server are for Redhat 4 and 5 and SUSE, will any of those actually work?

CentOS 5 :: Installing 5.4 With Multiple Raid Levels On A 4 Disk Array?

Nov 17, 2009

Our server is a CybertronPC I2XV9080 Imperium Tower. It is equipped with a supermicro X7DVL-I Motherboard and Quad 750 GB SATA2 RAID edition hard drives in a raid 5 array. We tried to install Centos on the Raid5 array with Device-Mapper as the LVM. In the BIOS SATA Raid was enabled and the ICH RAID code base option was set to [Intel].

Intel Matrix Storage Manager Option ROM V5.6.4.1002 ESB2
RAID
ID Name Level Strip Size Status Bootable
0 Raid5 Raid 5 64KB 80GB Normal Yes
1 Raid_5 Raid 5 64kB 2000GB Normal Yes[code].....

Can I have multiple level raids across the same array or would that lead to problems as above? Is the root cause of my problem the fact that intel raid5 is not supported for Linux as based on the following link http:[url]....

CentOS 5 Hardware :: Connect A RAID Box To The Server Via LSI 8880EM2 RAID Controller

Aug 3, 2010

I am trying to connect a RAID Box to the server via LSI 8880EM2 RAID controller.The raid box is FUjitsu Externus DX60 with raid 1 configured.The server is Fujitsu Primergy SX300 S5 with LSI 8880EM2 RAID card.The external raid box is being recognised by the raid controllers bios.

The server runs CentOS 5.5 64bit. I have installed the megaraid_sas driver from LSI website and MegaCLI utility but CentOS still fails to see the box.MegaCLI utility, when launched from CentOS, recognises the raid box, CentOS does not(no mapping being created in /dev).

I have also tried to create a logical RAID0 HDD on one physical HDD(as seen by MegaCLI) with MegaCLI utility in CentOS.The result was success and the new logical drive could have been used, but when restarting the server, the controllers' bios fails with an error (not surprised(one logical RAID0 on one physical HDD)) and configuration is being erased.

Has anyone tried connecting 8880EM2 controller to a raid box with raid configured on the box, running it all under CentOS and what were the results.

CentOS 5 Hardware :: RAID Or Non-raid HBA Recommendation?

Dec 10, 2009

I am going to be using CentOs 5.4 for a home storage server. It will be RAID6 on 6 x 1TB drives. I plan on using an external enclosure which is connected via two SFF-8088 cables (4 drives a piece). I am looking to try and find a non-RAID HBA which would support this external enclosure and allow to use standard linux software raid.

If this is not an option, I'd consider using a hardware based raid card, but they are very expensive. The Adaptec 5085 is one option but is almost $800. If that is what I need for this thing to be solid then that is fine, I will spend the money but I am thinking that software raid may be the way to go.

CentOS 5 Hardware :: SW RAID - Raid Devices Larger Than Total Devices

Dec 7, 2010

I'm working on a server and noticed that the to RAID5 setup is showing 4 Raid devices but only 3 Total devices. It's on a fully updated CentOS 5 system that only has three SATA drives, as it can not hold anymore. I've done some researching but am unable to remove the fourth device, which is listed as removed. The full output of `mdadm -D /dev/md2` can be see below. I've never run into this situation before.Anyone have any pointers on how I can reduced the Raid Devices from 4 to 3? I have tried

mdadm /dev/md2 -r failed
mdadm /dev/md2 -r detached

but neither work and since there is no block device listed I'm not quite sure how to get things back in sync so it's only seeing the three drives.

/dev/md2:
Version : 0.90
Creation Time : Tue May 25 11:07:04 2010
Raid Level : raid5

CentOS 5 Hardware :: Intel S5000Vsa And RAID Driver With Centos 5.4?

Dec 31, 2009

I've a Centos 5.1 server on S5000vsa Intel board with 6 bay HD in raid 1 mode (2 HD), and working fine until I've decide to make a yum update. Today the Centos is 5.4 but seems necesssary to upgrade the megasr driver for the raid function (i.e. , is not possible to contact the raid firmware trought Web Console 2). I've download the last megasr driver from Intel and I follow the instruction to upgrade the driver with s.o. installed, but when I start the server and choose via grub the new img boot file, the display show :

megasr.ko invalid module format -1 and stop. The linux version is the same in the machine (uname -a) and from the driver (2.6.18-164.9.1.el5). Another question : in Intel instruction spoken about megasr.o , but on img file I found a megasr.ko . I think instructions referre to old linux 2.4

CentOS 5 :: Does The Centos Kernel Support Growing Raid Devices

Oct 16, 2010

I'm setting up a raid 5 on several hard disks with a layer of lvm on top for good measure.I know the recent kernels support growing software raid, but since centos runs 2.6.18, I wanted to make sure it'll work. Does the centos kernel support growing raid devices?

Ubuntu Servers :: RAID-5 Recovery (spare/active) / Degraded And Can't Create Raid ,auto Stop Raid [md1]?

Feb 1, 2011

Could any RAID gurus kindly assist me on the following RAID-5 issue?I have an mdadm-created RAID5 array consisting of 4 discs. One of the discs was dropping out, so I decided to replace it. Somehow, this went terribly wrong and I succeeded in marking two of the drives as faulty, and the re-adding them as spare.

Now the array is (logically) no longer able to start:

mdadm: Not enough devices to start the array.Degraded and can't create RAID ,auto stop RAID [md1]

I was able to examine the disks though:

Code:
root@127.0.0.1:/etc# mdadm --examine /dev/sdb2
/dev/sdb2:
Magic : a92b4efc
Version : 00.90.00
code....

Code:
mdadm --create --assume-clean --level=5 --raid-devices=4 /dev/sda2 /dev/sdb2 /dev/sdc2 /dev/sdd2
As I don't want to ruin the maybe small chance I have left to rescue my data, I would like to hear the input of this wise community.

CentOS 5 Hardware :: How To Install CentOS On RAID 5.I

May 10, 2011

I have DELL R310 server with PERC 200H controller and RAID 5 configured already.This is my first time I want to install CentOS and seems like a new challenge for me I've read some articles on Wiki and posts on this forum and didn't find any information how to install CentOS on RAID 5.I only noticed that if there is fake or software RAID1 it should be switched off and made by OS configuration.I think PERC 200H is separate controller so RAID 5 is hardware RAID, is there anybody who can confirm ?My problem is that when I try to install CentOS it doesn't see any hard disks ... I looked for drivers on DELL web site and there is driver for Red Hat 6. I tried to install it using linux dd command but it doesn't recognize. Is there anybody else who met such problem ?

Fedora Servers :: Installing 11 On RAID 10?

Oct 16, 2009

I have a custom server built with Intel motherboard and RADI 10. The RAID controller is on the motherboard. I'm about to install fedora 11 x86 64 bit on it. Should I be experiencing any issues with anything that any of you have come across? I did a checksum check on the iso files and those were good. Also, someone sent me this link..

CentOS 5 Hardware :: Fake Raid Versus Hardware Raid After A Hardware Failure?

Oct 12, 2010

Recently while using a Highpoint 2310 (raid 5) I lost the mother board and CPU. I had to reinstall Centos and found it needed to initialize the array to function. Total loss of date. Question: If I use a true hardware card (3ware 9650se) and experience a serious hardware loss or the C drive can the card be installed with the drives on a new motherboard and function without data loss even if the OS must be reinstalled.

Ubuntu Installation :: Installing 9.10 On Drives That Used To Be In RAID

Jan 11, 2010

I was recently given two hard drives that were used as a raid (maybe fakeraid) pair in a windows XP system. My plan was to split them up and install one as a second HD in my desktop, and load 9.10 x64 on it, and use the other for mythbuntu 9.10. As has been noted elsewhere, the drives aren't recognized by the 9.10 installer, but removing dmraid gets around this, and installation of both ubuntu and mythbuntu went fine. On both systems after installation however, the systems broke during update, giving an "read-only file system" error and no longer booting.

Running fsck from the live cd gives the error:
fsck: fsck.isw_raid_member: not found
fsck: Error 2 while executing fsck.isw_raid_member for /dev/sdb
and running fsck from 9.04 installed on the other hard drive gives an error like:

The superblock could not be read or does not describe a correct ext2
filesystem. If the device is valid and it really contains an ext2
filesystem (and not swap or ufs or something else), then the superblock
is corrupt, and you might try running e2fsck with an alternate superblock:
e2fsck -b 8193 <device>

In both cases I setup the drives with the ext4 filesystem. There's probably more that I'm forgetting... it seems likely to me that this problem is due to some lingering issue with the RAID setup they were in. I doubt its a hardware issue since I get the same problem with the different drives in different boxes.

Ubuntu Installation :: Installing 10.04 On A Hp Z600 With Raid 1?

Nov 29, 2010

I am having trouble installing Ubuntu 10.04 on a HP Z600 with a two disc raid system. Is there a way to solve this without using the alternate cd (where the data files seem to be corrupted). The regular 10.04 cant find any drives on which to install, the 10.04 alternate cd�s all have corrupted files. I have tried downloading the .iso from two mirrors as well as from .torrent, all have data problems. The HASH checksums are fine, only the data on the burned discs are wrong. I have also tried using a USB install, but there are problems there aswell. At the moment I have win 7 on the disc as on the other partition, and have been using Ubuntu 10.10 (that is now an unbootable broken system), but have to downgrade to 10.04 becasue of software requirements.

The RAID seems to be an INTEL Raid . From HP homepage: Integrated 6 channel SATA 3 Gb/s controller with RAID (0, 1, 5 or 10) capability, optional SAS controller, LSI 3041E 4-port SAS/SATA, with RAID (0, 1 or 10) capability

Ubuntu :: Installing In A Intel S875WP1-E With Raid?

Oct 29, 2010

I have a server with an Intel S875WP1-E motherboard and 4 HD of 400Gb each. If i use the raid utility from the motherboard it doesn't appear during disk detection, so i disabled it. I've rebooted and launch installer from the DVD and it displays correctly 4 HD. I've configured them, installed the OS and installed GRUB in MBR (grub install /dev/sda /dev/sdb /dev/sdc /dev/sdd). But when i reboot it asks me to switch for a correct system disk.

I've look into BIOS configuration. If i make a raid array using the bios utility, i can choose any array in boot device priority, but if there is no array defined, i can't select anythig (but the DVD drive).

OpenSUSE Install :: Installing 11.2 On Existing Nvidia RAID?

Apr 6, 2010

I'm having some (well, a lot actually) of problems trying to get OpenSUSE 11.2 installed on my home PC. I am attempting to set up a dual boot configuration with Windows 7 installed on an bios Nvidia RAID 0.I was able to shrink the partition in Windows, and rebooted onto the net install for OpenSUSE (the MD5 validated DVD install failed multiple burns with "Repository not found"). I get into the graphical installer portion with no problems off the net install CD. However, the installer is not recognizing that there is an existing RAID 0. It lists the 2 SATA disks in the RAID separately. I can click on SDA1, and both SDB and SDB1 and it shows the disks, but does not recognize any existing partitions. If I click on SDA I get an immediate segfault in YaST and drop back to the text mode installer menu. It is loading the nv_sata module just fine.

From forum searches and google it seems that this is not usually a problem. My motherboard is a Gigabyte GA-M57SLI-S4 with the Nvidia Nforce 570 chipset running an AMD X2 64 3800+. Removing the stripeset and redoing it as Linux software RAID is not an option, I do not have enough space for a total backup/restore. Anything I do has to be nondestructive to the existing Windows installation.I really want to have a linux installation but between the DVD installer failing and now this issue I am about ready to give up on it.

Ubuntu Installation :: Installing With Raid 0 - Grub: No Such Device

Jun 29, 2011

I have a raid 0 setup with 2 x 1TB drives. I have an ASUS P8P67 LE motherboard and am using Interl RST for the Raid setup. I'm utterly ignorant of raid and therefore forgive any mistakes... I already had windows 7 installed and was attempting to dual boot ubuntu.

I installed Ubuntu from CD. The raid was picked up properly as only one drive by ubuntu. So it picked up the windows MBR and the main windows partition. I resized the main partition and used the "install ubuntu and windows 7 side by side" option. Installation went fine but once I restarted the PC I was welcomed by a grub rescue screen with the message: "error: no such device e196.....". Edit: I used the Windows 7 disc to repair the windows bootloader so I can now boot into Windows 7.

Before doing so I used gparted on the live cd to check the partitions on the drives. The only ones present were the MBR and windows one. So ubuntu seemingly didn't install... Although GRUB did... I was advised by someone on the ubuntu IRC chat to avoid trying to reinstall ubuntu at that point just in case there was an error in the partitioning process. I've since checked the state of the partitions from within windows and there's the MBR partiton, the windows partiton AND the partition that I created for ubuntu... 965MB of the partition that I created is listed as used space as well...

Hardware :: Installing New RAID Card Causes Existing Arrays To Have Bad Magic Number

May 13, 2010

I have two SAS RAID controller cards in a Dell server in slots 2 & 3, both with an array hanging off them. I went to install a third card into slot 1, but then when it boots it says two of my sd's have bad magic number in the super-block and it wants me to create an alternative one, which I don't want to do. If i remove the new card, the server boots perfectly like it did before I added the new card. Is the new card trying to control stuff that isn't hooked up to it because its in slot 1, so its confusing RHEL?
