Ubuntu Installation :: Build A RAID-1 System With The Two 320GB SATA HD's The Machine?
Dec 30, 2010
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 have a Asus P5Q-E with SATA Raid (fake Raid ?) with 2 250Gb disks on Raid 0 and have Windows 7 installed. Freed some space and want to install Ubuntu 11.04 alongside Win7. Install choosing the "alongside" option. Installed...reboot...grub rescue (error no such device). 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 went to install Ubuntu 10.04 on my home pc last night but I couldn't. The installers could not see my raid and even though I wished to install to a seperate HDD windows is installed to my raid. The windows MBR always overtook the Grub and whenever I start grub up it cannot find an OS or Kernel.
I have got an ASUS Rampage 3 Extreme [URL] and on it there are two 6.0 sata Marvell connectors: [URL]
In these two Marvell connectors are two WD velociraptor 10,00 rpm Raid 0 drives. On these two drives is installed Windows 7. The ubuntu installer cannot seem to see the raid pair and so does not install Grub correctly.

Am installing Fedora 10 on an old but good server that used to be a windows box. It has 2 sata disk raid level 1 on adaptec 2410SA card. Disks are clean no info even did a low level format and recreated RAID.. twice DVD boots and installs os on raid array and reports success. new volume appears under computer icon but cannot be mounted after reboot attempt reports Reading physical volumes. This may take a while... (it doesn't)
Volume group "VolGroup00" not found
Unable to acces resume device (/dev/VolGroup00/LogVol01)
mount: error mounting /dev/root on /ysroot as ext3: No such file or directory
input: PS/2 Generic Mouse as /devices/platform/i8042/serio1/input/input4
and then a blinking cursor with keyboard echo but its just copying reboot with install DVD does not show previous (unmountable) disk image and repeat of above process increases operator need for alcohol have "disable write cache for drives" as I found that is a post but after fedora install.I do not know what grub is for instance but once linux is booted (on other computers) I can muddle through ok in terminal mode.

I would like to build a bootable system image on an attached hard disk on a running CentOS machine.The hard disk would be moved to a headless server, where only SSH access would be available. It seems that all the documented install methods assume that the installation runs on the taget machine. In this case, I would like to create a bootable system image of CentOS on a running host system. The new install mage would generally have a newer version of CentOS than the running host system where the image is created. Also, I would prefer
to do a text-based install.
The reason for all this is that I have network access to several remote machines. I can ask disks to be moved between machines, but I have no physical access. In order to do software testing, I would like to have several system disks with different installed CentOS versions. It would be easer if I could build the system disks on one single machine. The hardware an all machines is very nearly identical.

A month or so ago, I built a new box. I installed a previously used 320gb hard drive and a newly bought 1TB hard drive.Before formatting anything, I copied all the contents from the 320gb hd to the 1tb hd using windows, since at that time for some reason I couldn't get Ubuntu to read the 1tb drive.At some point, I managed to format the 1tb drive as ext3 (don't know why I didn't have the ext4 option), and copied the files I wanted backed up from the 320gb to the 1tb drive.Once I did that, I prepared to delete the files from the 320gb drive. The thing is I can't find them anymore. I had made a /Storage directory, and now the 1tb is called like that too.The thing is, the 320gb drive is almost full, but it only has my Ubuntu installation. I keep my file in the 1tb drive, so the 320 should be fairly empty. How large can a Ubuntu installation get? 300+ GB???
Where should I look to see what I'm using the space with? I think (this was about two months ago) I created a directory Storagetempo or something like that. How would I look for it?I realize a solution could be just reinstalling Ubuntu on the 320gb drive, since I have all my other files on the 1tb, but that seems too "windowy" to me.

This question is going to flag me as being a bit green to Ubuntu, but I must confess that in 15+ years in I.T., I have never had such a hard time understanding the partitioning scheme. Here's where I'm at.
I installed from the 9.10 live CD and selected the option to use the entire disk. The system has an Intel raid controller built in to the motherboard and two 80GB hard drives in a mirrored configuration. The system has previously been used with both XP and FreeBSD and never had an issue with partitioning or, more importantly, getting the boot manager to work.
So the live CD partitioned my hard drives, installed all the software and mount points, and claims that everything is finished. When I reboot, no boot device is found. If I then boot again from the live CD and select the option to boot from the hard disk, it does and I am in fact typing this message from the system. However, nothing I can do will make the thing boot without the bloody CD.
I've spent hours trying to figure out how to make grub work, or how to fix the MBR but no luck. The drives don't show up as /dev/hda or as anything logical that I can discern, so I can't even construct a workable install-grub command. Doing a df gives me this:
[Code]...
which is not very informative, is it? FreeBSD was never such a pain to make boot.Frankly, I'm not very impressed that a clean install (non dual boot) on such a standard hardware configuration could be so difficult to make the boot loader work. Documentation on this subject is voluminous but very shabby. I have searched and searched and I cannot find any mention of hardware mirrored IDE or SATA drives, nor what dev they would show up as. Very frustrating. Every tutorial I've read on installing grub2 or grub just doesn't work, usually because the dev is not right.
Can anyone shed some light on this bizarre behavior and perhaps offer some advice that will allow me to boot this system without the use of a live CD?

I have a computer and I need to know whether its Sata-controller supports hotplugging. Therefore I (think I) need to know which Sata-controller is used in my computer. Can anyone tell me how I can find that piece of info?
ps. Some info on the environment: It is running an AMD Geode processor which only support IDE and therefore the board has a Pata to Sata converter build in. When I do 'lspci' it only shows the IDE connection:

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 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.

In order to get my Ubuntu system up and running on the Internet I need to install Sakis3g, and when installing, the system does not pick up ./Configure. My first thought was that the Build Essentials were not present but turns out that they are already installed, so now I'm at a dead end as I cannot finish my install. Has anyone else had any problems similar to this one?

Here is my system: I have dell poweredge 1950 PERC 6 with 300 GB raid system. It has two disks of each 300GB RAID mirrored system. I have few applications and data that reached around 280GB. As you know, poweredge 1950 we can have only two disk.
They are not mission critical. Hence, I wanted to remove the raid system and use as a non-raid system. By doing it, The applications and data can grow upto 600GB. I do not want to loose the data and setup. I am not so clear about RAID system and its conversion.

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 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 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

After keeping my old (laptop) computer going for 8 years, I've finally taken the splash and ordered myself a new PC, well the compoents any way to build myself a desktop this time.
I've just got a couple of questions.
I've got a 60GB SDD and a 1TB HDD. On the SDD I was planning on partitions for Ubuntu Swap Window partition, to run a Virtulisation, not dual boot.
Performance wise, is it best to install / on the SDD and /home on the HDD or /home on the SDD as well and just move music and videos ect to the HDD.
Just to complicate things, when ordering the HDD there was an offer to get a second 1TB HDD for an extra 11, so now I have 2. I was planning to set these up as RAID 1, which I believe I can do via the alternative install.
What would be the best way to then backup / . I guess it must be possible to schedule an image of/ to be copied across to HDD is it?
I did hear that RAID was a bit iffy in ubuntu, but looking about on the net things seem to be better 9.10 → Also the boot disk isn't RAID.
Are there any RAID or SSD issues I should be aware of?

I'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.
I have no idea what's going on and why mounting /home fails. I've written this post on Polish debian users forum, but no response - only to give more info, so I'll put it here also:

I received some errors while running a benchmarking script to determine my ideal raid chunk size. There are several errors in the kernel log regarding the sata link and eventually the two drives i have connected to a pci express x1 sata card were no longer present in /dev/
the script i was using is available here [URL]..system specs 1 500gb western digital drive (system drive)3 2tb samsung f4 drives (2 connected to pci x1 card (sata II) and 1 onto onboard sata port (sata I)) single core amd 64 on SiS chipset debian 64bit testing

I rebooted the machine and everything appears to be happy. What do these errors mean? What steps should i take to prevent them in the future so it doesn't end up corrupting the array?

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 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 was attempting to set up my ubuntu 10.04 system to load Synergy before log in to eliminate the second keyboard and mouse on my desk using these instuctions. However, once I log in I get a quick terminal screen which flashes so quick I can't read it then I am put back to the log in screen. I'm pretty sure I just need to remove the syntax I added to the /etc/gdm/Init/Default file and the /etc/kde3/kdm/Xsetup file and redo it (with less beer). The problem is that user account was the only user account I'd ever bothered setting up on this system and I can't get logged in.
Is there another account built in that I could use or do I need to hook the HD up to a SATA - USB cable and edit the files from another machine?

I want to stop using Windows because it sucks so i have downloaded all kind of distibutions from Linux. They give all the same error because it seems Linux has problems with Fakeraid. Now i have running OpenSuse in VmWare 7.0.1 but i want it as the only OS.
The installation goes fine but in the end it gives a Grub error because it cannot create the bootloader. It seems to be a common problem and i have done all the steps that i could find on Google.
I have two raid controllers. One is integrated in the mainboard from Asrock ALiveNF7G-HD720p R5.0 and OpenSuse sees it as a Jmicron controller.I have bought also a EM2001 2 Poorts PCI Controller SATA card with two harddisks in Raid 0 because Linux failed to install on the JMicron. On the EM2001 2 Poorts PCI Controller SATA it also fails with the same error.
I want OpenSuse 11.2 working on Raid 0. I know it must be some simple commands in the terminal through a live cd to correct the bootloader and do it manualy by Linux users but i'm a Windows user.
Can somewhone please tell me the exact steps and commands to install Linux on Raid 0 Fakeraid?
