Have Lian Li Ex 503 External Raid System, using 4x2TB, using Raidmode 10 for good performance [ Just for those who are interested: http://www.lian-li.com/v2/en/product/pr ... ex=115&g=f ]

I've been, for some years, an happy user of Highpoint HPT374 based RAID cards, using RAID 5 with decent performances (constantly around 90 MB/sec in read, and 60 MB/sec in write ). Old Athlon mobo , with 2.6.8 kernel. Now the mobo is dead, so I've got an Asrock A330GC (dual proc with 4giga ram), installed Debian with kernel 2.6.26 and moved the controller and disks , and the performances have dropped to a painful 9 MB/sec in write, measured with dd of a huge file (interrupted with kill -USR1 [pidof dd]).
Read performances are still around 90MB/sec, using hdparm -t , repeated many times , figures are constantly around 90MB/sec. I suspect some libata issue , in old kernel the raid was seen as hdb, now is sdb, some driver(s) of the PATA disks may be responsible. I've used the driver, from Highpoint v2.19 , the latest driver is broken (causes kernel oops during format of raid), I've informed Highpoint.
Here some info :

View 1 Replies View RelatedI've installed debian squeezy recently and for some reason I have problems with mounting /home partition during startup.
There's an error:Mounting local filesystems...mount: special device /dev/mapper/isw_bbfedcffgi_Volume0p6 does not exist. failed
I've tried using fsck - no result the file system is healthy, I've tried formatting it once again (fresh copy, no user data) and it's not working. What is more mounting the partition manually goes well - I can read the data and write to it. All other partitions are ok.

Win7 disk recovery and got access to Win7 again. Where is Ubuntu ? Nowhere... the free space continues free (not partitioned) and found no evidence of ubuntu install. Ok...second try with "something else" option, created /boot /swap and / partitions and installed grub on /boot partition (this time I want to use windows boot to choose...and if it fails the instalation again, at least I got Windows). Installed...reboot...grub rescue.
Again, the free space wasn't partitioned and the installer spend some time doing something but there is no evidence of ubuntu install. Also grub seems to be installed on first disk (even when I choose /boot as device bootloader installation) - I've used EasyBCD to create an entry on win bootloader and when I choose that got grub> (not grub rescue>).
Can Ubuntu be installed on such conditions ?
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?

I have a DL380 G3 HP server and I need to attach a 1TB hard drive. Of course the server only accepts SCSI and since I don't have a few thousand pounds to splash about I am looking at alternate methods. What I have done so far is buy a PCI SATA raid card and attach the 1TB drive to it. The BIOS seemed to be playing nice detecting it and allowing me to select the card. But it won�t see the drive.
Funnily enough though when I installed Linux on the SCSI drive during the install it saw the 1TB just fine and I could write to it. This has led me to believe that I could use GRUB (installed on the SCSI) to boot the 1TB as the hardware setup is working but the BIOS just can't handle it. So here I am with no real knowledge of GRUB. I was hoping someone could tell me where to begin with this and if it is even possible

I have a Dell Studio XPS running openSUSE 11.2 with dual mirrored disks (using Dell's SATA controller). Does anyone know how I can set up automatic monitoring of the disks so that I will be informed if either fail? I think smartd might be what I need here. Is that correct? I added:
/dev/sda -a -d sat -m <my email>
/dev/sda -a -d sat -m <my email>
smartd is running, but how do I know that it will report what I need? I also have a client with a Dell PowderEdge SC440 with SAS 5/iR also running openSUSE 11.2. They also require automatic monitoring. There doesn't seem to be a SAS directive for smartd. I notice that the newer release says it does support SAS disk. I upgraded to 5.39. On restart (with DEVICESCAN as the directive) I get the following in /var/log/messages for my SAS RAID disk.

I have 4 SATA's in a RAID 5 array using mdadm. Yesterday when I started the computer the RAID did not build/mount. When trying to load the array manually I get the message "mdadm: cannot open device /dev/sd(a,b,c,d)1: Device or resource busy" The drives should not be mounted or in use. The output of the drives in mdadm (mdadm --examine /dev/sd_1) looks normal.
The weirdest part is that rebooting often changes which drive is marked as busy, it can be any of the 4 SATA drives. how to figure out why/what is being used and how to disable it? I have tried searching for similar threads here and in google and haven't found anything similar or that worked.
I have three 640GB sata hard drives that I would like to put into a raid 5 configuration. I would like to opt for a software raid 5 so its hardware independent. I was trying to follow these instructions, but they seem a bit dated.

I bought a used server and it's in great working condition, but I've got a 2-part problem with the onboard raid controller. I don't have or use RAID and want to figure out how to stop or work around the onboard SATA raid controller. First some motherboard specs.: Arima HDAMA 40-CMO120-A800 [URL]... The 4-port integrated Serial ATA Integrated SiliconImage Sil3114 raid controller is the problem.
Problem 1: When I plug in my SATA server hard drive loaded with Slackware 12.2 and linux kernel 2.6.30.4, the onboard raid controller recognizes the one drive and allows the OS to boot. Slackware gets stuck looking for a raid array and stops at this point -........
I've recently started having an issue with an mdadm RAID 6 array that been operational for about 2500 hours.
Intermittently during write operations the array stalls, dropping to almost 0 write speed for 10-30 seconds. When this occur one or both of the 2 drives attached to a 2 port Silicon Image si3132 SATA-II controller "locks up" with its activity light locked on. This just started occurring within the last week and didn't seem to coincide with any update that i noticed. The array has just recently passed 12.5% full. The size of the write does not seem to make any difference and it seems completely random. Some times copying a 5 GB dataset results in no slow down other times a torrent downloading to the array at 50kb/sec does cause a slow down and vise versa.
The array consists of 8 WD 1.5TB drives, 6 attached to the ICH9R south bridge, and 2 attached to a si3132 based PCI express card. The array is formatted as a single ext4 partition.
Checking SMART data for all drives shows no errors. Testing read speed with hdparm reports what i would expect (100mb/sec for each drive, ~425mb/sec for the array).
The only thing i did notice is that udma6 is enabled for all the ICH9R drives while only udma5 is enabled for the si3132 drives. Write cache is enabled for all the disks. Attempting to set the si3132 drive to udma6 results in an IO error from hdparm.
The si3132 drive is using the sata_sil24 driver. Nothing of interest appears in the kern or syslog. During this time top shows very high wait time.
The s13132 controller appears to have the original firmware from 2006 loaded, there are some firmware updates available on the Silicon Image website for this controller that now appear to offer separate firmwares for RAID operation (some sort of hybrid controller/software thing the controller supports) and a separate firmware for standard IDE use.
Has anyone had similar issues with this controller? Is a firmware update a reasonable course of action? If so which firmware is best supported by the linux driver?
I know i'm not using its raid features but i've dealt with controllers that needed to be in raid mode for ahci to be active and for linux to work well with them. I'm bit ify at the idea of just trying it and finding out as it could knock 2 disks of my array out of action.
I'm trying to install a box with Ubuntu 10.04 LTS server with a typical LAMP system in order to replace my old Ubuntu 8.04 server I have at my school to have a "backup" system and also trying to replace NIS authentication with LDAP. Well I'm getting stuck on the first step: installation of base system.
I want to build a RAID-1 system with the two 320GB SATA HD's the machine has, I have a little experience in installing RAID because I installed my old 8.04 server with RAID-1 aswell.
I boot my box from an USB stick with Ubuntu 10.04 Server 64bit, the systems boots well, asks me about language, keyboard and so, finds the two NIC cards and the DHCP configuration of one of the card is done. Then it starts the partitioner.
One of the HD's already contains three partitions with an installation of a regional flavour of Ubuntu, the other HD only contains a partition for backups, I don't want to preserve all this stuff, so the first thing I do is to replace the partiton tables of both HD's with a new one. This is done without problems.
Then I go to the first disk, by example, and create a new partition, the partitioner ask me for the size, I write 0.5 GB (or 500 MB), then I select that it has to be a Primary partition at the beginning of the disk, all goes OK. Once created I go to the "Use as: " line, type Enter and select the option "Partition for RAID volume", when I hit Enter the error appears: the screen flickers in black for a second or two, then it shows a progress bar "Starting the partitioner..." THAT ALWAYS GET STUCK AT 47%!!!
Sometimes the partitioner allows me progress a little further (for ex. lets me activate the boot bit of the partition, or it allows me to make another partiton, even once the error didn't appeared until the first partiton of the second HD!!) but it always get stuck with the same progress bar at the 47%.
I've tried a lot of things: I downloaded again the ISO and rebuilt the USB, same result. Downloaded the ISO and rebuilt the USB from another computer, same result. Unplugged all the SATA and IDE drives except the two HD's, same result. Built a CD-ROM instead of an USB, same result. Downloaded the 10.10 server ISO (not an LTS), and the USB stick can't boot, is another error, but only to try.

I had Ubuntu 8.04 installed on server#1 and moved it to server#2. Everything works fine, including the changing of eth2/3 back to eth0/1. I was wondering if it's possible to use the nvidia onboard raid and make a raid 1 with this OS not getting wiped out. It's a bios level cheesy raid and it warns that it's erasing the data (which is didn't erase), but wont boot anyway. I'm assuming it's probably best to just create a software raid in the working OS with a fresh 2nd drive.

I forced my workplace to forgo windows and opt for linux for web and mail server. I'm setting up Centos 5.4 on it and I ran into a problem. The server machine is a HP Proliant DL120 G5 (quad core processor, 4GB Ram, two SATA drives, 150GB each attached to the hardware RAID Controller on board). RAID is enabled in the BIOS.I pop in the Centos disk and go through the installation process.
When I get to the stage where I partition my hard drive,it is showing one hard drive, not as traditional sda.but as mapper/ddf1_4035305a86a354a45.I looked around and figured that I need to give Centos the raid drivers. I downloaded it from:
[URL]
I follow the instructions and download the aarahci-1.4.17015-1.rhel5.i686.dd.gz file and unzipped it using gunzip. Then on another nix system, i do this:
dd if=aarahci-1.4.17015-1.rhel5.i686.dd of=/dev/sdb bs=1440k Note that I am using a usb floppy drive, hence the sdb. After that, during centos setup, i type: linux updates dd
It asks me where the driver is located. I tell it and the installation continues in the graphical mode. But I still get mapper/ddf1_4035305a86.a354a45 as my drive. I tried to continue to install centos on it. It was successfull but when i do a "df -h" it gives me /dev/mapper/ddf1_4035305a86......a354a45p1 as /boot
/dev/mapper/ddf1_4035305a86......a354a45p2 as /
/dev/mapper/ddf1_4035305a86......a354a45p3 as /var

/dev/mapper/ddf1_4035305a86......a354a45p6 as /home
Well i know why it's giving these, because i set it up that way, but i was hoping it would somehow change to the normal /dev/sda, /dev/sdb. That means that the driver i provided did not work. I have another IBM server (5U) with raid scsi drive and it shows the usual /dev/sda. It also has hardware raid. So i know that there is something wrong with the /dev/mapper/ddf1_4035305a86......a354a45p1 format.
First, is there any way that I can put the aarahci-1.4.17015-1.rhel5.i686.dd (floppy image) on a CD?. I really need to set this up with raid. I know i could simply disable raid in bios and then i would get two normal hard drives sda and sdb. But it has to be a raid setup. Any way to slipstream the driver into the centos dvd? The hp link i provided above, under installation instructions, there are some instructions titled "Important". But I couldn't get it to work.
Trying to install RHEL5-AS 64bit onto HP DL320 G6, with RAID being a mirrored array on the Smart Array B110i SATA controller. The RAID is configured in the BIOS and seems fine.

However, when the system boots after the install, the RAID is gone, and it's now seeing two drives, /sda and /sdb:
