Hardware :: 9690SA 3Ware BIOS RAID Setup?
Mar 17, 2011
I'm helping my brother setup a server he has. The server has a 3Ware 9690SA Hardware RAID card, and it has 4 x 2Tb 5400 RPM Samsung Harddrives. When I boot into the 3Ware BIOS, it recognizes all 4 drives, no problem. What he wants to do is install them in RAID 10 for a 4 Tb mirrored volume for performance and redundancy. When I try to create a RAID array with the 4 drives, and set it to use RAID 10, it only allows me to utilize 2079 Gb (1/4 x 8 Tb), which is half of what I would expect for this RAID config.
Assuming I go ahead and allow it to build the array with this volume, we can go on to install Fedora 14 with no issue, but still only 2 Tb are available. This is our first time setting up a RAID array like this, I've also tried enabling Auto-carving to insure that I have support for physical volumes larger than 2 Tb, but to no avail. With the version of Linux we're running, and the RAID card he's got, it should support greater than 2 Tb PVs either way though.

I'm attempting to install F13 on a server that has a 2-disk RAID setup in the BIOS. When I get to the screen where I select what drive to install on, there are no drives listed. The hard drives were completely formatted before starting the 13 installation. Do I need to put something on them before Fedora will install?

Why could there not be a 3-way or even 4-way RAID level 1 (mirror)? It seems every hardware (and at least the software I tested a few years ago) RAID controller only supports a 2-way mirror.I recently tried to configure a 3ware 9650SE RAID controller. I selected all 3 drives. Then RAID 1 was not presented as an option. Only RAID 0 (striping, no redundancy) and RAID 5 (one level of redundancy, low performance). Is there some engineer who thinks "triple redundancy is a waste, so I'm not going to let them do that"? Or is it a manager?
Mirror RAID should be simple, even when more than 2 drives are used. The data is simply written in parallel to all the drives in the mirror set, and read from one of the drives (with load balancing over parallel and/or read-ahead operations to improve performance, though some of this is in question, too).

I have several servers running 3ware 9750 raid controller cards. The 9750 does not have a driver built into the linux kernel and must be manually added during installation. This hasn't been a problem as I had a driver compiled for the kernel versions I was using.
There isn't a driver available precompiled for 10.04.3. I would like to compile one from the source code I downloaded from the manufacturer, but I am not sure where to start. I've looked for some sort of walkthrough or directions, but I haven't had any luck. I've compiled and installed software from source, but I have a feeling that drivers are probably a bit more complicated, especially since I will need to compile the driver on a system that does not have the same kernel version.

As I understand, Fedora 12 sets up Intel ICH (when set in BIOS) as mdraid instead of dmraid.I would like to setup my 2 SATA hard drives so ultimately my /boot partition is RAID1, my / (ROOT) partition is RAID 1, and my swap is either RAID0, or fstab referencing 2 partitions on 2 of the drives, both set with pri=0 (which supposedly is equivalent to striping of RAID0, performance wise).
Assuming Fedora 12 uses mdraid for my configuration in either instance, am I better of enabling, or disabling the RAID mode in the BIOS? This system is strictly Fedora--no dual booting, no Windows. Any performance gains; reliability benefits between either scenario?It's a Intel P35 motherboard with ICH9R. Storage configuration is either "AHCI" or "RAID"
I ran into some strange issues with dropping drives with the RAID set on in BIOS. When it was set, that gave me two md devices of md126 (RAID0, swap) and 127 (RAID1 split between / and /boot). I think I had md126p1 for the SWAP, and md127p1 for /boot and md127p2 for / Within purely software, i have:
/dev/sda1 RAID
/dev/sda2 swap
/dev/sda3 RAID
[code]...
I suppose unless the BIOS enabled RAID is supposed to be faster, I'll stick with a purely software route and keep the BIOS set to AHCI.

I have an MSI 845E Max Motherboard. I just purchased the computer USED. I have no manual and from all accounts of the online manual, this MB is doing the impossible.Connected to this MB are 2 WD 60GB hard drives. Bother are recognized in the bios. When booting from the live CD, and running the disk utility I can plainly see that there are the 2 drives and one striped array (using both of those drives).There is no settings in BIOS for any array. If I remove 1 of the drives, the disk utility sees only 1 drive but still sees an array. I can find no way to eliminate, recreate, oe manipulate this array in any way.To make matters worse, I attempted to install an older FREEBSD, using it it saw both drives (no raid). Using their Disk utility I re-partitioned both drives and continued the install. Unfortunately the version I had was an older one and it could not complete the FTP install (And I would rather have Ubuntu anyways). Though through this action I believe that I have destroyed the integetery of the raid and if it is to be used it needs to be fixed.So.. how do I fix something that my BIOS is not supposed to be capable of doing? Has anyone else experienced this issue.

I've played with Ubuntu, and a linux evangelist at work has talked me into trying it again.I happened to be wiping my machine, so my plan was to have Windows 7 and Ubuntu on one hard drive (100GB for Ubuntu, the rest for Windows), and the second hard drive for downloads, TV, films, etc.First I installed Windows, then I torrented the x64 Ubuntu 10.04 live CD iso, and burned it to a DVD. I booted from it and installed on the second partition, but I then found when I booted back into windows that my second hard drive wasn't there any more.
It didnt take long to work out that Ubuntu had installed using the second hard drive as a mirror. This is very confusing to me, as I've disabled RAID in my BIOS. I booted from the Ubuntu CD again and looked for options about this but didn't find any. Eventually out of frustration I just unplugged the second hard drive, but now when I boot from the CD to install, no hard drives show up for me to install to.

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...

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 just assembled a PC
amd x3 64bit
4 GB RAM
ATI HD4350
Asrock MB
2 HD WD 320 put into RAID 0.
To make this configuration, I have not enabled the raid from bios (since Ubuntu gave me problems) but I followed this guide [URL] (Official guides) to configure software RAID offered by ubuntu. Everything went ok and it works perfectly but when released the 10.04 and the system asks me to update, you think there will be some problem or leaving will be updated throughout unchanged RAID configuration?

I changed something in the BIOS which causes a kernel panic, if my card is installed (Ultra ATA/133 PCI-to-ATA Host Controller). I had it working fine til a month ago, when I installed some Linux on a HD on that card. That booted fine too, and I did some disk switching. Still all was well, but yesterday I tried to boot XP (2nd IDE master)(GRUB is Ubuntu/2nd IDE slave), and XP wouldn't load. I clicked here, and clicked there, and now XP and Ubuntu boot, ONLY if the RAIDbus card is Out. Put the card in, and I get a kernel panic/lockup. This HAS to be a BIOS function - nothing is different on the disks, including GRUB menu.

I recently dumped XP and installed Fedora 14. Since then I have been unable to access the BIOS Setup Screen.The Laptop is Fuitzu Siemans D Series 8820, The BIOS version is not in the manual. wouldn't have thought Fedora could write to the BIOS.Perhaps it is special key presses causing the problem.I am impressed with Fedora 14.

The 3ware bios shows all the external disks (its a 9690SA-8-E), they are setup as Jbod, but when I login to Centos I do not see my attached drives only my local ones. When using fdisk -l under root I see my attached disks but not my external array:

I'm trying to install Debian Lenny on my new Dell XPS 8100 Desktop with 2 x 1To SATA HD. (No Windows or any other OS install is present on the system) The Bios allows me to change the SATA mode to either "ATA" or "RAID"
- When SATA mode is set to RAID, the installation goes without issues, but when it comes to load into the system, I've got that Stage 1.5 Grub Loading... Error 2 problem. I assume this is due to the Bios "RAID" configuration. I then switched the SATA mode to "ATA" in the Bios and now I can see the menu that allows me to boot my debian install but that part actually fails too saying "ALERT /dev/sda1 does not exist"
- When SATA mode was set to ATA, I tried to re-install the system but this time my drive was not recognized by the installer: "No common CD ROM drive"

I wanted to take a current system with a working CentOS 4.7 LVM and move it to a 3ware 9650SE raid card so that I can mirror the drive and have a RAID1. The current system has 2 hard drives. One hard drive contains the CentOS 4.7 LVM install and the second drive is not part of the LVM. The second drive is being used for basic backups. I took a copy of the OS HD using dd and confirmed it worked by booting it up with the hard drive on the motherboard. When I connect it to the 3ware raid card with a new hard drive for the RAID1 and configure the 3ware raid card for RAID1, I get the "Volume Group "VolGroup00" not found" error. It gets past grub and then starts to load up but that is when the error occurs.
The error message exactly is:
Making device-mapper control node

Reading all physical volumes. This may take a while...

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 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
