Ubuntu :: Cannot Disable Fakeraid On Installation / Solve This?
Jul 31, 2011
I wanted to install Ubuntu 11.04 on my pc (dual boot with windows xp which is already installed on one disk).
I have a Asus P5K pro (motherboard) which has a integrated raid controller and i have two 500 GB hard disks.
On BIOS raid is disabled. On Windows i see 2 different disks (correctly)..
When i try to install Ubuntu, on the disk/partition stagei only see /dev/mapper/xxxxxx which should be the raid (i could be wrong). I tried booting inserting the nodmraid option but if i do i cannot see any disk.
what can i do to solve this?

My motherboard has a BIOS feature to support RAID1 for two disks. I know it's FakeRAID but that's what Windows can work with. I've read that Linux's built in softraid mdadm is better so I'd prefer to use that for Linux's own filesystems. Can I enable FakeRAID in the BIOS without it affecting Linux in any way? Is it possible for Ubuntu to read and/or write to the NTFS partition that's raided with the fakeraid?
Also, if running mdadm in RAID 1 how much risk is there of losing data if the computer crashes? Is e2fsck able to repair a filesystem on a RAID 1 setup?

I continue to have issues installing any of the newer version of Ubuntu on my ICH9 FAKERAID. I read that the GRUB2 issue with FAKERAID was solved shortly after Karmic was released. Did this somehow not get added to the Alpha 1 and Alpha 2 of Lucid? I would love to have Ubuntu installed on my main rig, but I do not want to fuss around with it forever...

I have 2 750GB harddrives with multiple NTFS and ext3 partitions and have just added two empty 1.5TB drives (with WD Advanced Format Technology) to the computer. I have several external drives of various capacities for temporary data storage. My final objective is to have two mirrored RAID arrays that I can access with both Ubuntu 10.04 and Windows Vista (which I still need for applications that aren't supported by WINE), and I'm trying to find out how to do this.
At the moment, the 1.5TB disks are mirrored in the BIOS settings, and I was able to add a blank NTFS partition to the array using GParted. However, I am now unable to mount any of my partitions (other than the Ubuntu one) and cannot use GParted to copy a partition to the RAID array (I get a generic resource in use message, but I have no other applications open and am opening GParted after a fresh boot).
My Ubuntu install is heavily customized, so I would prefer not to reinstall it if at all possible. If it matters, the OS was not installed as 10.04, but was updated incrementally over time, starting at Hardy Heron. I initially did an apt-get install of dmraid and kpartx after reading [URL]
For some reason, my 750GB drives are recognized as belonging to a broken RAID array even though they are not set up that way in BIOS.
HD configuration:
sda: (I cannot mount any of these partitions )
1: ext3 (Debian Installation)
2: ntfs (Vista Installation)
3: ntfs (Data)
[Code].....

About a year ago I bought a new compy and decided to get on-motherboard RAID, and by golly I was gonna use it, even if it wasn't worth it.
Well, after one year, two upgrades, a lot of random problems dealing with RAID support, and a lot of articles read, I have come to my senses.
The problem: I have a fakeraid using dmraid, RAID 1, two SATA harddrives. They are mirrors of eachother, including separate home and root partitions. I actually found the method I think I had used here: [URL]
The ideal solution: No need to reinstall, no need of another drive, no need to format.
My last resort: Buy a drive, copy my home directory, start from scratch, copy my stuff over.
PS: if it matters, I'm on 64 bit 10.04 LTS

I'm looking to shrink my windows partition on a raid0 array and create a mdadm ubuntu partition using raid0. Is this possible? can I just ignore the /dev/mapper device and use the standard /dev/sdx devices?

I have recently installed Ubuntu 10.04.1 lts server on my Intel "fakeraid" (software raid) (2x250 sata).To test my RAID 1 I turned off one HD and start the system.The first screen (Intel software screen) show Status = Degraded, but the system starts normally with just one HD.Then I turned off the system and turned on the HD again, so the first screen (Intel software screen) shows Status = Rebuild. If I enter in the software raid panel the folowing message is showed: "Volumes with "Rebuild" status will be rebuilt within the operating system"The system starts normally... but this message status stays permanently even I restart the system again

I have a MSI a6000 Laptop (that has given me a lot of problems installing Ubuntu.
I finally had to run Ubuntu from a CD in nomodeset
Then when I go to install Ubuntu the only options it gives (regarding my harddrive) are to format my whole hardrive or do the partitioning. I have seen screenshots though where there is a third option on the same page to install ubuntu alongside a prior OS and dual boot.
Does anyone know why the "install alongside a prior OS (dual boot)" option doesn't show up?

Computer: Dual AMD 280 Processors, Tyan Thunder K8WE S2895 Motherboard, 8x 2GB DIMMs.
Installed Fedora 10 86x64 from ISO burned to a DVD. Installation went ok, and computer needed to be rebooted at the end of the installation. Upon restart, Fedora 10 loaded to initial setup screen where user name, date, time, etc are set. At the end, as this is a stand-alone computer, the setup requests to send data of computer setup to Fedora.org and this request has to be denied. Pressing the Finish button ends up killing the system. The system doesn't reboot, what does happen is that the screen goes to black, and no signal is given to the monitor; the system hangs at this state. I've tried to see if giving the setup the ability to send the system data would change the end state upon pressing Finish, but nothing changes.

I have installed Ubuntu 9.10 (64 bit) as a dual-boot setup (along with Win 7) on my desktop. I can't emphasize how much faster Ubuntu loads when compared with Windows. There is only one problem though, I cannot figure out how to use my existing FakeRaid array (two 2TB hdds setup as RAID 1 - mirroring) to work with Ubuntu. I am NOT trying to install Ubuntu onto a raid array (I have Win 7 mounted on a separate boot drive , 4 hdds altogether, two for each OS and two for the RAID array). The raid array works fine in Windows and it's an Intel Raid Controller. How can I do the same for Ubuntu without losing any data? Is this possible?

I have just installed Ubuntu 10.10 server on and old pc to use it as a backup server for my and my kids pc's.The pc I use for the Ubuntu server has two sata disks on a fasttrak 378 controller, fakeraid as I have learned, and a single pata disk. I have installed ubuntu on the single pata disk and was planing to use the fakeraid as the samba share.
df -> Code: /dev/mapper/ubuntu-root
75287688 985120 70478136 2% /
none 1024032 248 1023784 1% /dev
none 1030124 0 1030124 0% /dev/shm
[code]....
How do I mount this fakeraid with a mirror setup? should I mount one of the disks, and if so which?

I have a dual boot (2 hard drive) system, and upgraded to 10.4. Booting into XP results in a flashing cursor that doesn't do anything. I know that GRUB screwed everything up, but I need to know what to do--and assume I don't know what I'm doing--to restore my dual boot ability.
Here's what I get after running a boot info script code...

When I did my upgrade and logged into Unity I had no panels at all.
Turns out it was code...
I had this to get smoother HD playback but it seems it wasn't needed anymore. Video playback was just as good as before even when I removed this.

I got gigabyte chipset with an raid support. Currently I have 2 hdd's running in raid 1. When I was first installing ubuntu 11.04 server my fakeraid was detected, and I assigned a name for it in the initial installer and it was auto-mounted (working 100%) ever since.
However I was forced to reinstall my ubuntu server, and this part was somehow skipped in the installer.
HDD can still be seen in /dev/mapper
I can see
control
jmicron_GRAID -> ../dm-0
jmicron_GRAID1 -> ../dm-1

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'm using Ubuntu Server 11.04
I have a HP Microserver which uses what I thought was a hardware RAID. It now turns out that it is fakeRAID.
I'm moving from Windows 2008 so currently I have 2x2TB disks in a RAID1 and formatted to NTFS. The RAID was working fine on Windows but it doesn't seem to work on Ubuntu. I have over 1.3TB of data currently on the RAID so I cannot format and start again. I need to find some way of getting Ubuntu to mount this RAID without having to format and create a software raid.
I'm unsure why it presents itself to Ubuntu as two separate disks as the RAID was setup on the RAID Array controller before it starts to load the operating system. Windows sees the RAID as a single disk and not two separate disks (although it can if I use a disk manager).
After some digging I have found out that the RAID format is PDC because Ubuntu can see the two disks and knows that they should be in a RAID but does not want to activate them. I don't want to go any further and experiment with commands until someone responds because I'd rather not risk my data.
Code:
chris@Chris-Server:~$ sudo fdisk -l
Disk /dev/sda: 250.1 GB, 250059350016 bytes
255 heads, 63 sectors/track, 30401 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes

I'm trying to install ruby on rails on Ubuntu 9.10. I'm following the instructions on this site:
http://castilho.biz/blog/2009/11/05/...-karmic-koala/
However, when I try to install Rails I get an error code...
It seems like gem can't access http://gems.rubyforge.org/gems/rake-0.8.7.gem for some reason, but when I try to go directly to that address I get the option to download it. Any ideas how to get around this problem?
I'm thinking if I can somehow tell gem to look for the file locally I can download it and install rails that way.

I just recently upgraded my kubuntu install from karmic to lucid and now it takes about 10-15 minutes to boot. Directly after the upgrade it was pretty slow already, but it got worse every day from then. The karmic version was a wubi install I moved to a dedicated partition using lvpm. Here are the results from the bootinfoscript code...

I am running 32 bit 2.6.32-26-generic-pae #47-Ubuntu SMP Wed Nov 17 16:14:46 UTC 2010 i686 GNU/Linux
Every time Update Manager updates the Kernel, the kernel and it's associated source code is upgraded, but the LINUX-HEADERS for the associated kernel are not updated.
This is a problem because without the updated linux-headers, my Nvidia drivers fail to recompile and load. A PIA. I then have to go to Synaptic Package Manager, find the appropriate linux-headers for the new kernel version, install it, reboot, and then Nvidia drivers load and function again.
Something is obviously messed up here. I likely caused the problem thus:
On first install of Ubuntu 10.04 LTS on this machine, it installed with the generic kernel. It saw/found the Nvidia drivers and loaded them OK (I may have had to do some Nvidia installs via Synaptic; I don't recall). My machine has more than 4GB ram, and I noticed it was not using nearly all of it. I researched and found the solution was to switch to the PAE kernel, which I did. Ever since then at every kernel upgrade, the Linux-headers fail to update, and have to be updated manually for Nvidia to function.
Now that I know what the issue is, it's not a big deal. However, Update Manager should know I need the Linux-Headers and upgrade them at every kernel update. How can I insure this happens auto-magically like the rest of this fine and beautiful KickAss OS?

My first attempt at seeking help has not been very successful. Probably to much of a narrative. If you want to know How I got in this mess see my first post.
Machine: Asus Eee PC 1015
What I know: I can't boot into anything but Live USB
What I think: Win7 starter is still there
Mint9 is lurking as well
Vista recovery partition exists
What I don't have: External USB DVD or CD drive
Win7 Recovery
What I need code...

I usually don't have problems installing Linux but Fedora won't install into 4 GB for me. I get to the partitioner, try to create a 4 GB partition, actually have 7 GB free, but it tells me there is no space on the drive. As I said, I usually don't get this problem but have not tried Fedora before and don't understand.

I'm using Karmic koala 9.10 64bit.Have three HDD, WD Raptor 36GB X 2 and Seagate 160GB.2 WD Raptors are striped (RAID 0), and all hdds are formatted by ext4.(Intel ICH9R raid) Problem is that, when reading/writing hdd heavily, system freezes a moment or very very slow down. When I used a windows XP, there's no problem. Moreover, one other machine, Karmic Koala 9.10 64bit and ext3, no raid, works very fine.
My system consists of,
Intel C2Q Q6600
2GB DDR2 6400 (1GB X 2)
Gigabyte P35-DS3R
Geforce 8500GT 256MB
[Code]...
If I format my hdd and re-install ubuntu, does it become better? or, if I use software raid provided by linux kernel, or if i don't use a raid?

I have a full working Mythbuntu 11.04 on a FakeRAID system (via ICH10R chipset). The OS is sitting on a 250GB partition and working fine. I am trying to get the 7.07TB partition mounted so that I can use it to store all my movies. When I mount it via the [URL] all works fine. When I reboot it cannot mount due to device being not ready or unavailable It appears the superblock goes missing at reboot. I have it formatted to ext4 with a GPT partition table. If I reformat and remount then all works fine again until I reboot.
