Ubuntu Installation :: Dual Boot SSD Non Raid - 1 Terabyte Raid 1 Storage "No Block Device Found"?
Sep 15, 2010
It's been a real battle, but I am getting close.I won't go into all the details of the fight that I have had, but I've almost made it to the finish line. Here is the set up. ASUS Z8PE-D18 mother board 2 CPU, 8 Gig Ram. I recently added an OCZ Agility SSD, defined a raid 1 virtual disk on the 1 terabyte WD HDD drives, which will holds all of my user data, the SSD is for executables.The bios is set to AHCI. Windows 7 installed fine, recognizes the raid VD just fine.
I installed Ubuntu 10.04 by first booting into try and mode, then opening a terminal and issuing a "sudo dmraid -ay" command. Then performing the install. I told it to install the raid components, and told it to let me specify the partitions manually. When setting up the partitions, I told it to use the free space I set aside on the SSD from the Windows 7 install as ext4 and to mount root there. Ubuntu installed just fine, grub2 comes up just fine, and Windows 7 boots with out a hitch, recognizing the mirrored partition as I indicated previously. When I tell grub to boot linux however, it pauses and I get the "no block devices found" message. It will then boot, but it does not recognize the raid array. After Ubuntu starts up I can run "dmraid -ay" and it recognizes the raid array, but shows the two component disks of the raid array as well. It will not allow the component disks to be mounted, but they show up which is annoying. (I can live with that if I have to)
I have fixed a similar problem before by setting up a dmraid script in /etc/initramfs-tools/scripts/local-top ... following the instructions found at the bottom of this blog:[URL].. To recap: My problem is that after grub2 fires up Ubuntu 10.04.1 LTS (Lucid Lynx), it pauses, and I get "no block devices found" It then boots but does not recognize the raid array untill I manually run "dmraid -ay". I've hunted around for what to do but I have not found anything. It may be some timing issue or something, but I am so tired of beating my head against this wall.

I have installed Ubuntu on my m1530 since 8.04 and currently dual boot Win7 and 10.10. I would like to dual boot on my PC, but I have run into a problem. I am not a pro at Ubuntu, but this problem I can not solve by reading forums like I have in the past.
I realize this is a common problem, but I have noticed people having success.
I have a M4A87TD EVO MB with two Seagate drives in Raid 0. (The raid controller is a SB850 on that MB) I use the raid utility to create the raid drive that Windows7x64 uses. I have 2 partitions and 1 unused space. Partition 1 is Windows, partition 2 is for media, and the remaining unused space is for Ubuntu.
I am running ubuntu-10.10-desktop-amd64 off a Cruzer 16GB flash drive that was installed via Universal-USB-Installer-1.8.1.4.
My problem like so many others is that when I load into Ubuntu, gparted detects two separate hard drives instead of the raid. I read that this is because kpartx is not installed on 10.10. I then went in LiveCD mode and downloaded kpartx from Synaptic Manager. Gparted still reported two drives. I opened terminal and run a few commands with kpartx. I received an error. (Forgive me I didn't write it down, but I believe it said something about a communication error. I will try again later and see.)
Currently I am reflashing the Cruzer with a persistence of 4GB. I am not familiar with this process, but I understand that my LiveCD boot will save information I download to it. I decided to try this method because I was going to install kpartx and reboot to see if this made a difference.
I am looking for any suggestions on a different method or perhaps someone to tell me that the raid controller or some hardware isn't supported. I did install ubuntu-10.10-alternate-amd64 on my flash drive, but fail to get past detecting my CD-ROM drive since it's not plugged in. If this method is viable, I will plug it in. I also watched the ..... video were a guy creates Raid 0 with the alternated CD, but it wasn't a dual boot and didn't use a raid controller from a MB.

I have (3) 60GB SSD. I want to use (2) in RAID 0 for Ubuntu and (1) alone for Windows 7.
What is the best way to get about this? I know how to create the RAID 0 array with the (2) disks and install Ubuntu on it. But how do I get the RAID array with Linux on it to dual boot with Windows 7?
Linux - RAID 0 (2) SSDs
Windows 7 - (1) SSD

Currently I have windows 7 x64 installed on a pair of raided ssd's using an x58 motherboard(ich10r) and I want to duel boot ubuntu x64 (either 9.10 or 10.04) on another harddrive (not part of the raided ssd's). Does anyone know if this can be done? I haven't found anything out there about this. I have tried to install Ubuntu from the CD. It gets to the install screen booting from the CD, but it doesn't let me install or try Ubuntu. I hit enter and nothing happens. I can look through all of the options but can't install or boot into Ubuntu.

I originally wanted to dual install 10.10 64 Ubuntu with Windows 7 64 RAID 1 HP PC, but RAID got corrupted and I could find no fix online except using fakeraid unsupported software. The whole thing blew my muind. I gave up after 4 or so reinstalls of windows 7 to fix RAID. So I decided to install a dual boot 10.10 Ubuntu i86 with my old WinXP i86. I kept getting these errors at boot up: unknown filesystem, file not found, out of disk, no such partion and so on. I tried just about every grub reinstall I could find, including article here: "Recovering Ubuntu after Installing Windows."
After a number of tries my friend installed Ubuntu successfully, but then when I installed windows xp I am stuck here, again. I did do the Reload grub tutorials again as well. I may just give up on WinXP and have my friend reinstall Ubuntu for me.

I am currently with Wubi 10.04 under Vista and my Dell XPS 630i has a 1 TB Nvidia RAID controller.First image (Option A) suggests /dev/sda as device for boot loader installation, while second image (Option B) suggests /dev/mapper/nvidia_bcidhdja.I think that the way of keeping the RAID would be using Option B as the device for boot loader installation. Would Option A break the RAID instead?

I'm having serious troubles to install ubuntu-10.04.1. My raid is an hardware raid with intel chipset. Note that win7 is already installed and working with my raid. I made some space from windows, to install Ubuntu (40gb). First, I run the installer, everything seems to be fine. I choose to install Ubuntu were there is the most space free (sorry, I'm not sure about the real terms used there).
Then my partition with the vista loader appears. So the installer can see my raid, and should work fine (everything is detected correctly). But once I'm in the end of the installation (around 95%), a pop-up appears, and tells me that Grub can't install in /dev/sda and it's a fatal error. I can choose an another destination, but it doesn't seems to work.

I am attempting to install Maverick on an older pc. It has (2) mirrored 153 GB SATA drives. I set aside 33GB for a linux partition, by shrinking the partition in Vista.
Choosing to "Install along side windows" is not an available option. I can only choose use who disk, or use empty area. I choose use the empty area, and the Ubiquity installer gets hung up when attempting to format the empty space as EXT4. When I scroll up on the output I notice some error messages referencing NTFS. When I use Gparted it shows a possible problem.

Warning:
The device /dev/sda1 doesn't exist

Probably /etc/mtab is missing. It's too risky to continue. You
might try an another Linux ditro.
Unable to read the contents of this file system!Because of this some operations may be unavailable.
The following list of software packages is required for ntfs file system support: ntfsprogs.
I ran chkdsk /r on the Vista partiton, in case there was a problem there. The issue still persists.

(This is for a 100% Clean install)
Q1) I was wondering if it is possible to Dual boot Ubuntu with Windows XP on a 1TB RAID-0 setup ?
Q2) Also, is it possible to create a SWAP partition (for Ubuntu) on a NON RAID-0 HDD ?
Q3) Lastly... I read GRUB2 is the default boot manager... should I use that, or GRUB / Lio ?
I have a total of 3 HDDs on this system:
-- 2x 500GB WDD HDDs (non-advanced format) ... RAID-0 setup
-- 1x 320GB WDD HDD (non RAID setup)
(The non RAID HDD is intended to be a SWAP drive for both XP and Ubuntu = 2 partitions)
I plan on making multiple partitions... and reserve partition space for Ubuntu (of course).
I have the latest version of the LiveCD created already.
Q4) Do I need the Alternate CD for this setup?
I plan on installing XP before Ubuntu.
This is my 1st time dual booting XP with Ubuntu.
I'm using these as my resources:
- [url]
- [url]
Q5) Anything else I should be aware of (possible issues during install)?
Q6) Lastly... is there anything like the AHCI (advanced host controller interface) like in Windows for Ubuntu?
(Since I need a special floppy during Windows Install...) I want to be able to use the Advanced Queuing capabilities of my SATA drives in Ubuntu.

I've recently had trouble reinstalling my Ubuntu system as I was getting various unusual errors as described in my old thread here. I thought it was probably something to do with my RAID-0 array which was pre-installed on my laptop from purchase being corrupted or something like that (if it's possible). I decided to simplify things for myself (not understanding RAID arrays much) so I just removed the RAID array and installed Windows and Ubuntu on the now separate hard disks. It worked fine.
I noticed quite a significant performance drop, however, with even Ubuntu boots taking longer than 30 seconds despite my laptop being both high-spec and only a few months old. Windows, as you can imagine, was dreadfully slow. I wasn't entirely convinced that this was entirely due to the loss of the RAID array - as even low-spec laptops with presumably no RAID arrays are supposed to boot Ubuntu in under 30 seconds apparently - but I read that RAID-0 arra

Could any RAID gurus kindly assist me on the following RAID-5 issue?I have an mdadm-created RAID5 array consisting of 4 discs. One of the discs was dropping out, so I decided to replace it. Somehow, this went terribly wrong and I succeeded in marking two of the drives as faulty, and the re-adding them as spare.
Now the array is (logically) no longer able to start:
mdadm: Not enough devices to start the array.Degraded and can't create RAID ,auto stop RAID [md1]
I was able to examine the disks though:
Code:
root@127.0.0.1:/etc# mdadm --examine /dev/sdb2
/dev/sdb2:
Magic : a92b4efc
Version : 00.90.00
code....
Code:
mdadm --create --assume-clean --level=5 --raid-devices=4 /dev/sda2 /dev/sdb2 /dev/sdc2 /dev/sdd2
As I don't want to ruin the maybe small chance I have left to rescue my data, I would like to hear the input of this wise community.

I did some linux installation in the past but never get along with it. now I decided to give it another shot because I need it for the information security class I'm taking.
I have a gigabyte ga-p35-ds3 with 2 WD 320GB HD on a raid 0 array (motherboard raid). I have windows 7 x64 already installed on the raid and would like to install ubuntu 9.10 x64 dual boot with it.
The problem is that the installation does not recognize the win7 on the disk, it does recognize the raid as 1 640GB disk but with nothing on it so I can't processed with the installation without loosing the win7 installation with everything on it.
another weird thing is that after I quit the ubuntu installation and restart the computer the raid 0 fail to load. after I shutdown the computer and start it again the raid is up again and the win7 loading ok.
I have to install it in a dual boot with win 7 without reinstalling everything from scratch.

I'm having a problem installing RHEL-5 on my system. I have Windows 7 installed so far on a Dell XPS workstation that came with hardware RAID 0. I have 2 x 500 gb hard drives. So I went in Win 7 and partitioned my disk to leave about 75 gb of unallocated space to install RHEL-5 on. I load the RHEL-5 DVD into my disk, restart my comp, and just follow installation steps. Use about 73 GB as an ext3 partition for the RHEL-5 and have about 2 GB reserved for swap space. RHEL-5 installs, and I'm all done. However, when I reboot the computer, the GRUB boot loader fails to load. I'm directly taken into Windows. How do I recover GRUB so I have the option of loading into RHEL-5?

I just installed SUSE 11.2 as dual-boot with WinXP on an older system that has a 160GB PATA drive and a 500GB SATA RAID drive. I left about 80GB on the PATA drive unpartitioned to accommodate SUSE. During the initial installation attempt, SUSE was determined to install on the RAID drive instead of the PATA drive, so I disabled the SATA drivers in the BIOS to force the installation on the PATA drive. This was successful, but now there is no access to the RAID drive from SUSE because there is no driver and it is not mounted. I reactivated the SATA drivers in the BIOS and the RAID drive reappeared in WinXP with everything intact. The SATA drives now appear in SUSE under Hardware Information as "/dev/sdb" and "/dev/sdc" and the listed driver is "sata_sil".
So how do I get the RAID drivers installed in SUSE and then mount the drive so it can be browsed/modified from Dolphin? I would also like to be able to browse/change this drive from other computers on my home network through samba, just like with WinXP.

I have a pre-existing setup with Windows XP Professional and CentOS5.5 on a dual boot setup with the Linux drive setup as the primary drive hosting the grub menu.
I am replacing these machines with new updated ones and they have windows setup on a RAID0. I think it would be easiest to follow my previous setup and move the RAID to secondary SATA ports and put the linux drive on the primary SATA port, or should I just change the boot order in the BIOS to have the secondary linux drive boot first?
can I move a RAID setup to secondary controller ports without breaking the RAID?

let's say this system has 3 hard drives. Drive #1 and #2 are RAID 0 and Windows7 lives there. It is a hardware RAID, not software.
On Drive #3 Ubuntu has been installed using WUBI - it boots up and works okay - but it does not see the RAID array.
Do I just need a linux driver to be able to see & mount my "Windows" RAID0 array? Or is this even possible? Can anyone point me in the right direction?

I have a raid 0 setup with 2 x 1TB drives. I have an ASUS P8P67 LE motherboard and am using Interl RST for the Raid setup. I'm utterly ignorant of raid and therefore forgive any mistakes... I already had windows 7 installed and was attempting to dual boot ubuntu.
I installed Ubuntu from CD. The raid was picked up properly as only one drive by ubuntu. So it picked up the windows MBR and the main windows partition. I resized the main partition and used the "install ubuntu and windows 7 side by side" option. Installation went fine but once I restarted the PC I was welcomed by a grub rescue screen with the message: "error: no such device e196.....". Edit: I used the Windows 7 disc to repair the windows bootloader so I can now boot into Windows 7.
Before doing so I used gparted on the live cd to check the partitions on the drives. The only ones present were the MBR and windows one. So ubuntu seemingly didn't install... Although GRUB did... I was advised by someone on the ubuntu IRC chat to avoid trying to reinstall ubuntu at that point just in case there was an error in the partitioning process. I've since checked the state of the partitions from within windows and there's the MBR partiton, the windows partiton AND the partition that I created for ubuntu... 965MB of the partition that I created is listed as used space as well...

I am in a situation where I am stuck with a LVM cleanup process. Although I know a lot about AIX LVM , but this is first time I am working with Linux LVM2. Problem is that I created two RAID arrays on storage, which appeared as mpath0 & mpath1 devices (multipath) on RHEL. I created logical volumes and volume groups and every thing was fine till I decided to clean the storage arrays and ran following script:
#!/bin/sh
cat /scripts/numbers | while read numbers
do
lvremove -f /dev/vg$numbers/lv_vg$numbers
vgremove -f vg$numbers
pvremove -f /dev/mapper/mpath$numbersp1
done
Please note that numbers was a file in same directory, having numbers 1 and 2 in separate line. Scripts worked well and i was able to delete definitions properly (however I now think I missed one parted command to remove the partition definition from mpath device. When I created three new arrays, I got devices from mpath2 to mpath5 on linux and then I created vg0 to vg2. By mistake, I ran above script again for cleanup purpose and now I got following error message
Cant remove physical volume /dev/mapper/mpath2p1 of volume group vg0 without ff[/B]
Now after doing mind search, I now realize that I have messed up (particularly because mpath devices did not map in sequence to vg devices and mapping was like mpath2 --- to ---- vg0 and onwards). Now how I can cleanup the lvm definitions? should i go for pvremove -ff flag or investigate further? I am not concerned about data, I just want to cleanup these pv/vg/lv/mpath definations so that lvm can be cleaned up properly and I can start over with new raid arrays from storage?

* I am implementing mass storage device on a test board.
* It contains NAND flash.
* Using corresponding "udc driver" and "g_file_storage" I could make my test board enumerate as mass storage device on my Linux machine.
* my 16 MB pen drive (test board) is now ready for read/write.
But there are some Bad Blocks on the NAND.Hence copy is not complete. Although on Linux machine there is no error message. Now , what is there in a normal pen drive which manages the Bad Block or what am I missing so that such Bad Blocks are managed.
Here is the error I get on my test board :

I am interested in turning my home server into something that I can store backups on. I do photography and therefore have a lot of photos. I use Mac OS X for my photo editing, so it must be accessible from my Macbook. I am new when it comes network storage servers, so what would be the best solution for me to be able to backup my photos seamlessly? I would like it easy enough so others can backup files without any terminal commands and such. What would you suggest? CIFS? RAID? iSCSI?
