Hardware :: Raid Setup Not Recognized After Updating RAM
Mar 9, 2011
My specs are as follows:
Motherboard:Asus Crosshair Formula IV
CPU:AMD Phenom� II X6 1090T Black Edition 3.2GHz
RAM:Corsair Vengeance 8GB DDR3 1600MHz CL8 Dual Channel Kit (2 x 4GB)
HDD: 1 Sata 750 GB Hard Drive
HighPoint 3120 PCI-E TrueRaid Controller, 2x250GB set as Mirroring.
So everything is working good. I have windows on the 750 GB Sata hard drive, and OpenSuse 11.3 on the Mirrored raid setup. I have grub as the bootloader, it loads windows and linux without error. So i have 8 gb of ram installed, but i have room for another 8 gb. This is where the error starts. After i install the other 8 gb of ram, which is corsair vengeance as well, windows will boot, but not linux. When i remove the newly installed ram, linux boots no problem. I tried putting the ram back in, then reinstalling linux again, but as i go through the setup, linux doesn't recognize the RAID setup. Like i can see it there, but i can't use it, partitions don't show up.Now i remove the install cd and tried to start linux again, still error. The error it gives me goes like this:
>Trying manual resume from /dev/disk/by-id<...>-part2
>resume device /dev/disk/by-id/<...>-part2 not found (ignoring)
>Waiting for device /dev/disk/by-id/<...>-part1 to appear: .............
>Could not find /dev/disk/by-id/<...>-part1
>Want me to fall back to /dev/disk/by-id/<...>-part1? (Y/n)
Wether i select Y or N, it takes me to a shell. I tried using fdisk in the shell to check if /dev/sda the linux setup has any partitions on it, and no it does not recognize any of it. When i use fdisk on /dev/sdb to list the partitions it works. So only the raid setup gets affected by the increase in RAM.

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...
[root@ftpserver ~]# df -h
Filesystem Size Used Avail Use% Mounted on
/dev/md1 16G 3.0G 13G 20% /

I've been all afternoon trying to install Ubuntu Lucid on my fakeRAID 0 configured (2) HDDs and am unable to set GRUB up. The fake RAID setup is provided by Intel Matrix Storage Manager, it is correctly enabled and the BIOS is also correctly set up -- in fact, I've managed to install Windows 7 with no significant hitch. After struggling with partioning the drives (had to follow advice I found on a very helpful guide online [0]), creating the filesystems AND getting Ubuntu's installer to actually do what it is supposed to do, I now cannot seem to set GRUB up. My system, as it stands, is unbootable at all; via live CD only.
This is how the RAID0 dev is partitioned:
Code:
# fdisk -l /dev/mapper/isw_ecdeiihbfi_Volume0
Disk /dev/mapper/isw_ecdeiihbfi_Volume0: 1000.2 GB, 1000210694144 bytes
255 heads, 63 sectors/track, 121602 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 131072 bytes / 262144 bytes
Disk identifier: 0x6634b2b5 .....

I have got a mid-aged server which i upgraded with a simple SATA-Raid-Controller with a VT6421A chipset.I attached two Samsung 750 GB Hard disks and created directly after the POSt screen a nice Raid 1 array. Ubuntu will recognize it as well as windows (which I would never ever use... ;-)).SuSE 11.1 (we need this OS for confirmity) will simply just recognize both disks in the partitions overview. The point "RAID" remains empty.
Are there any hints out there how I can enable the whole raid stuff in open suse? Do I need to integrate other drivers / modules to get thinks working?

I'm having a problem with the installation of Ubuntu Server 10.04 64bit on my IBM xSeries 346 Type 8840. During the installation the system won't recognize any disk, so it's asking which driver it should use for the RAID controller. There's a list of options, but nothing seems to work. I've been searching the IBM website for an appropriate driver, but there is no Ubuntu version (there is Red Hat, SUSE, etc). I was thinking about downloading the correct driver onto a floppy disk to finalize the installation, but apparently no 'general' Linux driver to solve the problem here.

I have a system with: - 1 SSD "boot" drive - 3 HDDs in RAID 5. I created my RAID 5 set in BIOS - P6X58D motherboard/Intel Software RAID - Looks and works fine in Windows 7 (Ultimate) 64-bit. I installed Ubuntu 10.04 using wubi - both Windows 7 and Ubuntu systems are on the SSD THE PROBLEM Ubuntu does not appear to recognize my RAID 5 set - when it loads I see a "/dev/sd_ 10 failed" error (sd_=sda, sdb or sdc) along with "no such file or directory" - I can see my 3 HDDs in 'Disk Utility,' but the space/partition information is incorrect - I reinstalled all packages related to RAID (dmraid, etc.)

Currently running F10 on a RAID1 software raid array in Linux (not hardware or BIOS). I used the F13 install disk to boot and selected install/upgrade. Problem is that the Anaconda portion never sees the RAID device.
I tried passing the "nodmraid" argument to the kernel during boot. Other research suggested that the auto=md switch should be appended to the mdadm.conf file. No results from either solution.
Anaconda does not see the /dev/md0 or /dev/md1 and consequently it only offers an installation option.
What I would prefer is to upgrade.

We ran out of space on our server hard drive, so I installed 2 x 1GB drives, set them up as a software RAID1 array, copied the contents of /home to it, mounted it as /home for testing. Everything OK, so I unmounted it, deleted the contents of the /home folders (don't worry, we're backed up), then remounted the array. Everything was fine until we rebooted. Now I can't access the array at all; during booting the error "mount: special device /dev/md1 does not exist" comes up twice, and manually trying toe same issue. The relevant line from fstab reads:
/dev/md1 /home ext3 defaults 0 0
However, using webmin shows only md0, the RAID0 device on which the OSD was originally installed. There is no /dev/md1 device file. The mdadm.conf file reads as follows:
# mdadm.conf written out by anaconda
DEVICE partitions
MAILADDR root
ARRAY /dev/md0 level=raid0 num-devices=2 uuid=76fd4050:fb820568:c9bd3a59:ad3e70b0
So it's not listed; I'm assuming this is significant. Am I right, and whether I am or not, what can I do?

When trying to install Kubuntu 10.04 32-bit (or Ubuntu 10.04 64-bit) it does not show me any hard drive to partition in the 'Disk Setup' (I've clicked all the buttons on that screen to see if I can encourage it!) and will not let me past that point in the installation process (because, obviously, no root file system has been defined). I have done something very bad to my computer. As an aid to selling my computer, I decided to (try to) install Windows 7. I booted into a live Ubuntu CD and used Gparted to reformat my hard drive. After several issues with the Windows boot CD I decided to pull up FastBuild Utility, and did something which included deleting LD and Defining LD again. Didn't make any difference with the Win 7 install. I am now trying to return my computer to a functional state in the sanctuary of Kubuntu 10.04.
Tried installing Win XP which I have installed successfully on another computer. Got an error message: "Setup did not find any hard disk drives installed in your computer" - presumed that was because of something I did with FastBuild Utility (2006). I've tried as many different options in this as I think could make a difference. Booted into DR-DOS and deleted partitions and created a FAT 32 partition. Booting into the live Ubuntu 10.04 CD again and used GParted to create an NTFS Primary Partition taking up all the hard drive. As above and deleting all partitions in GParted. Checking into BIOS and changing the SATA Operation from 'RAID On' to 'RAID Autodetect / ATA' (Now changed back again to the default 'RAID On.').
Loaded Defaults in BIOS - I've been running Ubuntu 10.04 x64 on it since it came out with these settings. At all points I have tried to install Ubuntu 10.04 64 bit, Kubuntu 10.04 32 bit (and Win XP) with no success. In the Kubuntu install, when I get to the Disk Setup part of the installation process it offers me no information whatsoever. My hard drive has all partitions deleted because of my last action in GParted. May need to define a partition. What as? I'm still convinced that my playing in FastBuild Utility (2006) is probably the root cause of this, and so quite likely to be a good place to go to solve this. I think I've set everything as it was, but can't be 100% on that.
My Computer:
Dell Inspiron 1721, AMD Turion x64 dual core, FUJITSU MHW2120BH 120GB HDD.

I have 2 drives and wish to use the following partition setup.
sda1 /boot 1GB ext4
sda2 / 50GB ext4 raid 0
sdb1 / 50GB ext4 raid 0
Unfortunately only Ubuntu server has the option to make a raid in the install. Can somebody point me to a howto on something like this up. I'm thinking I will want to install onto a sdb2 set up the raid and copy the file system to the raid.

I have set up a RAID1 array and am trying to test if its is set up correctly/if errors are detected, reported and recoverable.
Started up the mdadm monitor with:
Code:
I set the RAID array to a faulty state by doing:

However I do not get any problem reports to my e-mail address. When I test the mdadm I get this result:

When I look in the postfix folder, sure enough.. there is no main.cf file there... but there IS a file named 'master.cf'. I am running Ubunto 9.10 with default components - have postfix but no sendmail.

I have a situation where I need to setup some sort of storage solution with Raid 5 redundancy. I was thinking that Linux would be the way to go but I am not certain what platform would be best.
I was thinking running two SATA RAID controllers to get me somewhere between 4 - 6 TBs in Raid 5. I am very comfortable with ubuntu now and would love to use it. I have also used FreeNas in the past but would love to have a full OS on the machine if at all possible.

I am just getting into the Raid world with my home server. what i have:
Asus M3A78-CM (may be wrong, cant remember for sure) Motherboard with 6 Sata2 Connectors
3 2TB Sata2 Drives
2GB of DDR2 Ram set in bank A
AMD Dual Core (i'll know what it is when i get the system booted)
What i am trying to figure out is when i build this system, I will put in the HDD's into Sata Ports 1-3 and in the BIOS i will setup a RAID 5 Array. Now, do i just format and partition like normal? Would it be better to have a smaller, and better performing Sata2 for the system so i can have the raid be only for file storage?
In what i have read about this, i need to format each drive into two partitions at least but i do not know what needs to be done, The guides just vaguely say something about two partitions and then move on (trick of the trade? keep all of us in the dark? LOL) I would like to have a raid for my storage and a faster disk for the OS and home directories. But if it cannot be done then thats how it is. So do i put the TB drives in Sata Ports 4-6 and my other drive in Sata Port 1?

I'm setting up a backup server using Centos 5.3 and an Adaptec 5805 raid card and discovered that I can't use a raid setup that is over 2TB in size as the boot drive. What I eventually did was set up 2 raids on the same set of 4 drives so that I have a 200Gb 'drive' for booting and a 2.6TB 'Drive' for data. I want to keep the OS in the raid setting so I have some protection instead of having a dedicated stand alone drive for the OS. This will be for a company wide backup server and I want to minimize the possibility of drive failure for the OS as well as the Data.
I was able to install and reboot the system and everything seemed to be working but after some working on it a bit I did a reboot and wound up with a non-booting system. I can boot to the rescue mode with the install dvd and mount the original system and I even tried to reinstall the grub setup per instructions I found on the net but still I get a system that hangs up after it asks if I want to boot from the CD. If I take out the CDROM option from the boot lineup in the bios I stop at the same place minus the boot cd prompt.
I'm guessing it is something to do with one of the raid drives being over 2TB but I'm booting from a 200gb sized raid so I'm really at a loss for what to do next??
Is what I've described the correct way to handle booting up with a large raid or is there another way to reconfigure the drives as one big 2.8TB raid and use something other than grub to boot to it?

My system includes two 120GB disks in fake raid-0 setup. Windows vista is installed on these.For Debian I bought a new 1 TB disk. My mission was to test Debian and I installed it to the new disk. The idea was to remove the disk afterwards and use windows as it was before. Everything went fine. Debian worked perfectly but when I removed the 1 TB disk from system grub will show up in boot in grub recovery mode.
Is my RAID setup now corrupted? Grub seems to be installed on the other raid disk? Did grub overwrite some raid metadata? Is there any way to recover the raid setup?

I'm setting up a web server but I have no experience with RAID. I would like to try this configuration if possible:
2 x HDD 500GB RAID1
1 x HDD 20GB (logs and tmp)
The old 20GB drive I would like to use it to store logs and temporally files (mounted in /var/log and /tmp respectively). With this I'm trying to reduce some disk usage in the RAID drives. In my idea, it would be better to write the access/error logs of the web server in a separated drive to the one serving the files which may increase speed... sounds crazy?
One problem is that during the installation, If I set the RAID automatically it will try to use my 20GB HDD as well in the RAID... Does it will work if I set the RAID first (removing the 20GB HDD) and then set the mount points in it after the installation?

I've just finished setting up a RAID 1 on my system. Everything seems to be okay, but I have a very slow boot time. It takes about three minutes between the time I select Ubuntu from GRUB and the time I get to the login screen.
I found this really neat program called bootchart which graphically displays your boot process.
This is my first boot (after installing bootchart). I'm not an expert at reading these, but it appears there are two things holding up the boot, cdrom_id and md_0_resync. I tried unplugging my CD drive SATA cable, and this is the new boot image.
It's faster, but it still takes about a minute, which seems pretty slow on this system. The md0 RAID device is my main filesystem. Is it true that it needs to get resynced on each boot?
I'm not sure how to diagnose my CD drive issue. The model is a NEC ND-3550A DVD RW drive. I should also note that there's a quick error message at startup about the CD rom. It's too quick for me to read it, just one line on a black screen saying "error: cdrom something something".

I have a Dell workstation, 2 HDD, HDD 1 setuped Red Hat 5.3 with LVM, and that HDD 2 is empty, not install RAID 1. And, I want to setup RAID 1 (hardware RAID)...but, have a problem. I don't want to lost data on HDD 1 when I setup raid, I try ghost or backup it, but when I restore, it error because LVM is setup on that.

I was wondering what is the proper way to setup a hardware based mirrored raid. I have two 2TB drives and a nvidia based raid on the motherboard. I used the nvidia raid manager to setup a Mirrored array consisting of those two drives. The total shows as 1.81TB array.
I boot into OpenSuSe 11.3 and in the partitioner I see two drives (dev/sda and dev/sdb each 1.82TB) listed instead of a single RAID drive. Am I doing something incorrectly that two drives show up instead of the array? Does something need to be enabled?

I want to build a 6xSATA RAID 5 system with on of the disks as spare disk. I think this give me a chance of 2 of 6 disks failing without losing data. I am right?
Hardware: Intel ICH10R
First I will creat a 3xSATA RAID 5, after I will add the spare disk and after that I will add the others disks. This is what I think I should do.
Step 1:
Create RAID Device
Code:
mdadm --create --verbose /dev/md0 --metadata 1.2 --level=5 --raid-devices=3 /dev/sda1 /dev/sdb1 /dev/sdc1
I read that "--metadata 1.2" is the best option. It is true?
Create filesystem on the RAID device
Using this method of calculation:
* chunk size = 128kB (for RAID 5)
* block size = 4kB (recommended for large files, and most of time)
* stride = chunk / block = 128kB / 4k = 32kB
* stripe-width = stride * ( (n disks in raid5) - 1 ) = 32kB * ( (5)- 1 ) = 32kB * 4 = 128kb
Then:
Code:
mkfs.ext3 -v -m .1 -b 4096 -E stride=32,stripe-width=128 /dev/md0
Step 2:
Add spare-disk
Code:
mdadm --add /dev/md0 /dev/sdd1
Is this enough?
Step 3:
Adding disks:
Code:
mdadm --add /dev/md0 /dev/sde1
mdadm --grow /dev/md0 --raid-devices=4
fsck.ext3 /dev/md0
resize2fs /dev/md0

I am rebuilding two microsystems servers and I need some advice to make my dreams come true.I want to setup the servers in a RAID configuration and want to install a GUI Linux application to manage a file server, manage a subnet, and host a Moodle on my subnet.I am planning to use Asus eee netbooks running Linux as my client computers. I basically need to be able to get my kids on the web and be able to have them use some open source office suite tools. No major crunching. I'll have two Macs for that.

I'm asking for an advice about the setup of a large volume: I have 2 disks of 1 Tb each and I want to merge them in a single volume/partition. I am in doubt about setting up a LVM, a RAID0 device or both. I know that RAID0 has no redundancy but I will manage a backup on other media, so that I can take advantage of the stripe feature in terms of I/O performance. On the other hand LVM let me to easily manage and expand the volume in a near future. Am I correct? Anyway I don't know if I can ever setup both and in which order. First LVM then RAID, I suppose.

I'm trying to setup a RAID 5 array of 3x2TB drives and noticed that, besides having a faulty drive listed, I keep getting what looks like two separate arrays defined. I've setup the array using the following :
sudo mdadm --create /dev/md01 --verbose --chunk=64 --level=5 --raid-devices=3 /dev/sdb /dev/sdc /dev/sde
So I've defined it as md01, or so I think. However, looking in the Disk Utility the array is listed as md1 (degraded) instead. Sure enough I get :cat /proc/mdstat
Personalities : [linear] [multipath] [raid0] [raid1] [raid6] [raid5] [raid4] [raid10]
md1 : active raid5 sde[3](F) sdc[1] sdb[0]
3907028992 blocks level 5, 64k chunk, algorithm 2 [3/2] [UU_]
So I tried getting info from mdadm on both md01 and md1 :user@al9000:~$ sudo mdadm --detail /dev/md1
/dev/md1:
Version : 00.90
Creation Time : Sun Jan 9 10:51:21 2011
Raid Level : raid5 ......
Is this normal? I've tried using mdadm to --stop then --remove both arrays and then start from scratch but I end up in the same place. I'm just getting my feet wet with this so perhaps I'm missing some fundamentals here. I think the drive fault is a separate issue, strange since the Disk Utility says the drive is healthy and I'm running the self test now. Perhaps a bad cable is my next check...
