CentOS 5 Hardware :: CentOS 5.3 3 Disc Software Raid 5 Array - "hardware Failure" Messages At Bootup
Apr 28, 2009
I've just setup a new centos 5.3 server with a 3-disc raid 5 software RAID array. I've setup other software raid 5 arrays on this same hardware, whilst testing, and had no trouble... I only just installed 3 new drives and performed a new install from scratch.
Hardware is: 4800XP X2 64-bit, 2GB RAM, Albatron KI-690G mainboard with Marvel SATA controller (I think) - 4 ports.
SATA port 0 is system drive (OCZ vertex 32GB SSD)
SATA port 1 is Western Digital "green" 1TB 8MB cache SATA 2
SATA port 2 is Western Digital "green" 1TB 8MB cache SATA 2
SATA port 3 is Western Digital "green" 1TB 8MB cache SATA 2
Ports 1-3 in software raid MD0 (raid 5)
All of this was configured in the GUI setup, with LVM on top of software RAID 5 mounted on /var. Partition size is ~1.9TB
Trouble is I get all sorts of "hardware failure" messages at bootup and the MD driver reports it was only able to bring up 2 out of 3 drives in the RAID set... however the RAID set formatted fine during the setup?
Here is the relevent dmesg output...

Round two:I am trying to install a RAID 1 array on my system. I already have another RAID 1 array in there. I am using the BIOS RAID option to set up the array.Here's what dmraid -r tells me:
# dmraid -r
/dev/sda: pdc, "pdc_bajfedfacg", mirror, ok, 3906249984 sectors, data@ 0
/dev/sdb: pdc, "pdc_bajfedfacg", mirror, ok, 3906249984 sectors, data@ 0

I'm not able to spin down my harddisks in raid array. I did hdparm -S 240 /dev/sdb and the same for the second hdd. Smaller values like 2 minutes work. I don't have log files on this disks. How can I determine, which processes are accessing these disks? I have apache and samba running. Nobody is accessing the server.

I have a raid 1 array which I did setup on a Centos box. I can configure the array fine the problem is every time is restart my machine I can no longer see the array and have to go create it all over again. I tried doing a few searches on it but have came up with nothing so far.

1. One of my hdds failed (sda) in software raid 1. I rma'd the hdd to western digital and got another one. Now do I have to format it before putting it in my centos server? If yes, how do I format?
2. Also since sda drive failed, I gotta mark sda as failed in raid. Then remove the sda hdd, and pop in the new hdd for sda? Or do I switch sdb to sda and put the new hdd in sdb's place?
3. After that add it to raid correct, then once raid rebuilds I have to do grub? Can grub be done via ssh only? or do I need to be at the datacenter or get kvm?
4. Last question, I've got a supermicro hotswap hdd case, so do I need to shutdown server while I replace the hdd's? I just want to be sure I do this correctly.
The following is the guide that I will be using, please look at it and let me know if that is the correct procedure: [URL]. Another thing, when the hdd (sda) failed I put it back into raid, but the hdd has bad sectors that is why m replacing it.

I've been having troubles with software raid. In particular, the raid array becomes un "assembleable" after reboots. The config is CentOS 5, 4 sata discs (one by 160 containing OS, no raid and 3 2TB disks configured as a RAID 5 array - no spare drive). These drives were configured in anaconda and all seemed to go well (the drive and its lvm partitions worked and it finished rebuilding overnight). A couple of reboots later the drives cannot be assembled anymore and the machine won't boot. The error message says:
mdadm: /dev/md0 assembled from 1 drive and 1 spare - not enough to start the array.
Of course there are 3 drives and no spares in the array as configured. Manually starting the array with mdadm --assemble --scan gives the same message as does assembling the drive by specifying the individual parts. /proc/mdstat does recognize the 3 drives and when I look at the partition tables in fdisk, they show as being software raid. What could be wrong or steps to diagnose? I tried configuring the raid drives manually before going the anaconda route. Also, does anyone know I can edit the /etc/fstab file to disable them so the machine will at least boot. The (Repair filesystem) shell has the / drive mounted r/o.

Following scenario: My server in some data center on a different continent with two disks and software raid 1.
One day I see that a disk failed (for example with /proc/mdstat). Of course I should replace the failed disk asap. Now that I think about it, I am not sure how. What should my email to the data center support guy mention to make sure that guy doesn't replace the wrong disk?
With hardware RAID it is very easy, because the controller usually has some kind of red LED indicator. But what about software raid?

I need to mount my raid array on CentOS 5.2 samba server.
Here are my hardware specs:
Motherboard: Tyan S2510 LE dual PIII
CPU's: Intel PIII 850ghz socket 370
Memory: 4 gig Crucial 133 ECC SDRAM
OS: 2 x'x IBM Travelstar 6.4 gig 2.5 hard drives, (low heat/noise)
Storage: 4 x's Seagate 500 gig IDE 7200 rpm
RAID controller: 3Ware 7500-12 controller, (RAID 5) (66 mhz PCI bus)
NIC: 3COM 3C996B-T gigabit NIC, (66 mhz PCI bus)
I have the 2 IBM's set as RAID 1, (mirror) and the 4 Seagates as RAID 5, (1.5 TB) I have installed the OS with minor problems, (motherboard doesn't like the 2.6.18-128.1.14.el5 kernel, removed it from my grub.conf).
My problem is mounting the RAID array. I have done the following:
formatted with fdisk;
fdisk /dev/sdb
Then formatted with the following command;
mkfs.ext3 -m 0 /dev/sdb
The hard drive was formatted with the ext3 files system, but I have mounted it as an ext2 file system as I don't want 'journaling' to occur. I then edited my /ect/fstab like this: .....
Then: mount -a
When I go into my "home" directory and type ls, I get the following:
[root@hydra home]# ls -l
total 24
drwx------ 2 zog zog 4096 Jun 23 15:50 zog
lrwxrwxrwx 1 root root 6 Jun 23 15:46 home -> /home/
drwxrwxrwx 2 root root 16384 Jun 23 15:34 lost+found
drwxr-xr-x 2 root root 4096 Jun 23 17:18 tmp
Why my home directory is showing under home?

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]....

I have a home samba server with a 3ware Escalade 8506-8. I have 5 x 500 gig hard drives in a RAID 5 array. Recently, my 8506 died and I need to get a new one. However, I saw a 3ware Escalade 9500S-12 on ebay for about $20.00 dollars more than a replacement 8506-8.
My question is, if I put my drives on the 9500S, will it recognize my existing RAID array? Or will it want to build a new RAID array and format all of my data?Hope I have asked this question clearly, little short on sleep this week.

I have a 10x2tb disk array that i'm trying to build into a single software raid 5 i have tried this 2 times now the first it made it to 58.7% and the machine locked up and the array would not restart after a reboot. On my 2nd try all was looking good until about 50% i noticed that the speed dropped in 1/2 and that ksoftirqd/2 is taking up a lot of cpu (about 90%) the md0_resync and md0_raid5 are also taking 60-90% when the build started they took 7%. when i do a dmesg i see a lot of the message compute_blocknr: map not correct.
For a little info on the physical setup this is running on an Atom 510 with 2GB of mem the drives are connected to an addonics 4-Port RAID 5 / JBOD SATA II PCI Controller using the sil3124 chipset. I'm using 2 addonics 5X1 SATA Port Multiplier connected to the controller to get the 10 drives attached. All drive show up and don't seem to have any issues. I'm running a fully updated as of 3/20/10 version of centos 5.4
I will let this continue to run over night but i expect it to be locked up by morning if it follows what the last attempt did.

I went to setup my linux box and found that the OS drive had finally died. It was an extremely old WD raptor drive in a hot box full of drives so it was really only a matter of time before it just quit on me. Normally this wouldn't be such a big deal however I had just recently constructed an md RAID5 array of 3 1TB disks to act as an NFS mount for basically all of my important files. Maybe 2-3 weeks before the failure I had finished moving all of my most important stuff onto that array. Now I know that the array is intact. All the required data is sitting on those disks. Since only the OS level disk failed on me I should be able to get a new disk in there, reinstall ubuntu and then rebuild that array. how exactly do I go about doing that with mdadm? Do I create the array from the /dev character devices like when I initially built the array?

I have 4 WD10EARS drives running in a RAID 5 array using MDADM.Yesterday my OS Drive failed. I have replaced this and installed a fresh copy of Ubuntu 11.04 on it. then installed MDADM, and rebooted the machine, hoping that it would automatically rebuild the array.It hasnt, when i look at the array using Disk Utility, it says that the array is not running. If i try to start the array it says :Error assembling array: mdadm exited with exit code 1: mdadm: failed to RUN_ARRAY /dev/md0: Input/output error
mdadm: Not enough devices to start the array.I have tried MDADM --assemble --scan and it gives this output:mdadm: /dev/md0 assembled from 2 drives - not enough to start the array.I know that there are 4 drives present as they are all showing, but it is only using 2 of them.I also ran MDADM -- detail /dev.md0 which gave:
root@warren-P5K-E:~# mdadm --detail /dev/md0

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.

So I didn't notice when I setup my CentOS 5.5 server that I left / as RAID 0 on md1. All the rest are RAID 1. Is there a way I can modify the array to RAID 1 without a risk of data loss? I'm glad I caught this before I setup any other services. I've only setup smb so far...

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.

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.

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

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

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?

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 ?

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.

I have a NETGEAR ReadyNAS NV+ with four 1TB drives in a RAID-5 array. This is our primary file storage. This has previously been backed up to a hardware RAID-0 array directly attached to our Windows server. The capacity of this backup array is no longer sufficient. So the plan was, take a bunch of 200GB to 320GB drives (And a 750) I had kicking around, chuck them in a couple of old SCSI drive enclosures I have collecting dust, attach them via IDA/SATA-to-USB adaptors to a USB hub, attach that to the server, create a JBOD array spanning the disks, and back up the NAS to that. Performance is not an issue as this is just to be used for backup, with the idea being as near to zero cost as possible (Spend so far = NZ$100�ish).
The first hurdle I struck was Windows not supporting Dynamic Disks on USB drives (Required to create a spanned volume). At first I resisted using another machine (i.e. a machine running Ubuntu) as I didn't want to dedicate a piece of hardware to backing up the NAS. I then decided it would be acceptable to do this via a VM, which is what I've done.So I have 10.04 running under VMWare Server 2.0.2 under Windows Server 2008 R2. The disks are all presented to the VM. I wasn't sure if I was going to end up creating the array under LVM or something else, but I noticed Disk Utility has an option to create an array, so I tried that. When I add two 250GB drives, the array size is 500GB. When I then add a 160GB drive, the array size drops to 480GB. Huh? If I keep adding disks (Regardless of order) the final array size comes out at 1.8 TB, as per the attached screenshot. Now with the following drives, I expected something more like:
160 + 250 + 250+ 750 + 250 +200 + 200 + 250 + 320 + 250 + 320 = 3.2TB
Am I missing something or making a false assumption somewhere?

I have a service I've made an init script for, and it's added to chkconfig, which shows it "on" in all the correct runlevels. When I start or stop this service using the "service" command all is fine, but it does not start on it's own at bootup. I am currently at a loss to determine why it is not starting. Here is the script:
#!/bin/bash

I am having trouble trying to get the kernel to accept some command line arguments for parport_pc during bootup. I have a custom base board with a PC-104 CPU board connected to it through the ISA bus. On the base board I have 3 parallel ports mapped to addresses, 0x150, 0x158, and 0x160. Only the first one needs interrupts, the second two do not. So, on bootup I load the parport_pc module like this modprobe parport_pc io=0x150,0x158,0x160 irq=3,none,none I have been running an older RedHat kernel, 2.6.11 for the past few years and this has been working flawlessly. I had the above modprobe call in /etc/rc.d/rc.local.
Now I am trying to set the system up to use CentOS 5.5, kernel 2.6.18-194.el5. What happens is, the module inserts OK, but the system never recognizes the ports. (i.e, they do not show up in /proc/ioports)
But, if I log into the system, then rmmod parport_pc, then re-modprobe it as above, it works just fine and now my ports are visible. This is an embedded system, expected to just come up and run, so kicking it into action by hand is not an option.
I have tried putting a parport_pc.modules file in /etc/sysconfig/modules so that it will be seen by rc.sysinit, (some site I found while googling said modprobes need to be done earlier than in rc.local),and again, the module gets inserted but the ports are not seen. I have also tried putting rediculously long pauses between each step of the modprobing of the parport stuff;

I am having issues with my sound..Sometimes when I boot up I get the following when I cat /proc/asound/cards
[digitolx@ssureshot-pc ~]$ cat /proc/asound/cards

HDA NVidia at 0xd6000000 irq 225[code]....
This is wrong, now My audigy should be default with the UART (onboard) being secondary. I will be setting this up for my microphone / headset.Now if I restart I will get the following..

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.

During the boot-sequence of jessie there is more text flying by on the screen (including some errors or warnings) than I can read thorugh fast enough. I don't think this is very serious stuff, and if it were I could always look at dmesg and or syslog i /var/log but I would find it really convenient to log these messages in a file instead of sifting through or grep-ing dmesg.
When duckduckgoing this matter I found [URL] ....
I installed tried bootlogd but when configuring it to "yes" and rebooting nothing comes up in /var/log/boot.
Then I saw this line in above link
If you use systemd as your init system, you may need to use systemctl to debug boot problems.
