Ubuntu Installation :: Getting Raid 0 Motherboard Swap?
Sep 10, 2010
i just got a new motherboard for a router/server at home i got something beefier, the deal is that the raid 0 i've got running on the old chipset is running ubuntu desktop edition and i just wanna install the server edition on the new beefier board, i've a /home partition in the raid if i swap the boards will that crap out what i've got in my /home dir... or can i just swap the boards and make a fresh install on a root partition without messing up my /home partition?

I just upgraded to an ASUS P8P67 Pro (Sandy Bridge) motherboard and moved my old hard drive to the new case. Windows 7 and XP are running smoothly. Ubuntu, however, doesn't detect the Ethernet adapter or doesn't have a suitable driver. ASUS doesn't offer Linux drivers for this motherboard. Is there a way to make Ubuntu revert to a default, working driver?

(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 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 just went out and bought stuff to build a new computer, and among the parts was a Gigabyte ga-890fxa-ud5 motherboard ([URL]). The board has 3 (well, 4, but we'll stick to the 3) main sata interfaces, with 2 slots per interface, allowing 6 sata drives. In slot_0 i put my blu-ray drive, in slot_1 i put my drive that will host the OS and its partitions, and that is in the sata connector pair on the left. The middle sata connector pair (slot_2 and slot_3) i have 2 2tb drives, and in the sata connector pair on the right (slot_4 and slot_5) i have 2 1.5tb drives.

I'm in the process of setting up my very first ubuntu server.
Using 10.04 and has 2gb ram
I am using Ubuntu's software raid (mdadm)
It will be a file server, with 4 hard drives (3 in RAID5 and 1 as a spare)
All 4 drives have 2 partitions:
Partition 1 - 100mb
Partition 2 - The remaining drive space
I setup the first 3 drives' partition 1's to be RAID1 with the 4th drive's partition 1 as a spare. This is where I'm mounting "/boot" (it's my understanding that /boot cannot be on a RAID5). I setup the first 3 drives' partition 2's to be RAID5 with the 4th drive's partition 2 as a spare. This its where I'm mounting. I believe so far I'm setup correctly to be able to deal with a drive failure and the system should operate just fine. What I don't know what to do is with the /swap. I want to retain the ability to be able to operate with a drive going down. But I have also read warnings about putting /swap on a raid. How would you setup /swap?

I am unable to hibernate my computer while using Ubuntu and I figured out the reason--Ubuntu is not using my swap partition. I would follow the existing tutorials on setting up a swap partition after installing Ubuntu, but since the volume uses hardware RAID 0, the swap partition is not assigned a /dev/ entry (like /dev/sdxx) and I am not sure how I can mount it.
Here is what I have:

The weirdest thing I have ever saw happened today after i rebooted my server.I have an IDE drive with fedora core 12 installed.I have 4 500g sata drives that I made a FD partition on.
Created the raid using mdadm and had a sh script that assembled and mounted.This worked just fine for 4 days and about 6 reboots.then the other day I noticed an odd amount of net traffic coming in and out of the box and took it down to do some router configuring.
After I brought it back up and ran the sh script, I got a weird error, /dev/sdc device was busy. so I did an fdisk /dev/sdc, and sure enough it had a swap space and boot partition. I deleted em, rebooted and now I'm stuck at the grub screen. Somehow my drive names got fubared and I don't know how to recover my system.

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.

Recently my motherboard has been dying and the warentee is gone so I decieded it was upgrade time. I need to know if there is anything special I need to do for Ubuntu to work on my computer after the new hardware is installed. I currently have a 32 bit motherboard and processor and am switching over soon. GRUB 2 handles my boot and I know I have some extra stuff to do on windows 7 but I was wondering what I needed to do to get my computer to boot up after the upgrade.

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.

Has anyone done a recent install of the latest Ubuntu on a EFI motherboard? Last time I tried (right as 11 came out) I had horrible graphic errors during the install, problems install grub2-efi, and then even when I got everything installed I had graphic errors on boot up that rendered the install worthless. I think I am going to have to go to a different linux distro, which I am not really that happy about, but I need linux on this computer. know experiences with ANY linux distro and recent EFI motherboard installs.

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 reinstalled XP to do a dualboot with 10.10 yesterday. All was fine. Today I went through and installed everything windows needed, and everything seemed fine. Then I upgraded the BIOS on my motherboard, and suddenly everything isn't fine. I can boot to Ubuntu just fine. But when I select Windows from the GRUB menu, it just sits there with a cursor on the screen now.

I want to start using Ubuntu again but I gave up ages ago trying to get it to work with my Gigabyte EP45-DQ6 motherboard.I cant run from disc and I can't install.If I try to run it just takes me to a black screen with blinking cursor and that's all it does.If I try to install, basically the same.I can't get anywhere doing anything, so where do I start?How can I get it working on my system?By the way, this is with the latest Ubuntu.No, it's not a corrupt download or burn. I tried to download and burn, didn't work.I ordered a free cd, it did the same.This is an issue that is NOT related to the disc or the download of Ubuntu.

I just assembled a new computer with Intel Core I3 processor and Asus P8H67 motherboard and 4 MB of memory. It has a 2TB Hitachi Deskstar Hard Drive and Asus DVD. I am trying to load Ubuntu 10.10 directly (without first loading Windows) without success.
I have tried 4 separate downloads of Ubuntu - 64 bit, 32 bit with Desktop and Alternative. I have changed a variety of parameters and various tricks suggested on other threads. The Desktop (32 and 64) versions get me to Busybox shell with message (Initramfs) Unable to find a medium using live file system. The Alternative version hangs with the messages:
RAMDISK: Couldn't find valid RAM image startgin at 0;
No filesystem could mount root, tried ext3, ext2, ext4, fuseblk;
Kernal panic - not syncing VHS;
Unable to mount root fs on unkown block(1,0).
For parameters I think have tried them all (but not in all combinations). I tried exiting twice from BusyBox as suggested on forums but that just hangs the system. I also turn off the quiet and splash to try and see what is going on....but it is too complex and goes to fast for me to follow.
A final suggestion was that the P8H67 is too new for Ubuntu 10.10 and to try the new version 11 coming out...I am new to Linux and reluctant to try a Beta

I got an Asus M3A78-T motherboard last year, along with a Phenom 9650 CPU and 2GB of RAM. I originally tried to install Sabayon, but it would occasionally hang while running. I decided to give Fedora another try (wasn't happy with FC4 a few years back) at the constant chiding of my friend.
My first try was with the x86_64 Fedora 10 ISO, using an IDE hard drive and CDROM. It would hang a little bit into something like 'copying system files, at the same place every time. Thinking it was a bad burn, bad iso, or something (checksum and image verification passed) I went ahead and got the DVD ISO. The DVD would always hang a little bit into "Formatting file system." At this point, I have tried EVERY other combination of hardware - swapped out ram, CPU, PS, bought SATA hard drive and DVDROm drive, unplugged the mouse, and even the case pigtails for USB and Firewire. It always hangs in the same place. Somewhere along the process, I took the motherboard back and exchanged it for a new one. Still fails, and in exactly the same place.
The system hang is a hard lockup. Mouse freezes, no keyboard activity (even LED status changes.) The drive activity LED will go out and the progress bar stops advancing.
I'm surprised I'm not seeing anyone else with this problem - I thought this board was a bit more prevalent, but I'm guessing not! What's my next step? I would create a bug report, but I don't know what subsystem is causing the hang. I suspect SATA drivers, but I'm not sure how to test that.
And one other clue - I get a scrambled video screen before it comes up to the first X install screen:
It only lasts for 5 seconds or so, then comes up okay.

RAM for older machines like I use is fairly cheap these days. But flash memory is just as cheap or cheaper. So I'd like to ask about the feasibility of expanding my system's memory using flash memory. And about whether creating a partition for swap on the flash memory, or whether a swap file on the flash device, is the better way to go.
By flash memory I have in mind mainly USB sticks or what are sometimes called "pen drives." But I do also have CF and SD cards that, with the proper cheap adapter (one of which I already own for adapting CF) could be used to create extra swap space. So, what is the current consensus on the feasibility/advisability of using flash memory for swap? I've read about the limited write cycles of flash being an argument against using it for swap. But recent reading indicates to me that the limited write cycles problem applies mostly to older, smaller-capacity flash memory. Some will come out and say that, for larger-capacity flash memory, the life of the device is likely to exceed the amount of time your current computer will be useful (I think I've seen estimates in the range of 3-4 years life--minimum--for newer, higher-capacity flash memory).
A more persuasive argument I've heard against using flash memory for swap is that access times for these devices can be much slower than SATA, and maybe even IDE, hard drives. That would certainly dictate against using flash memory for swap.
So, how about some input on this issue? Anyone using flash memory for swap? If so, what kind (e.g., usb stick or SD/CF)? Are you using a swap file or a swap partition? How's system performance? Likewise, has anyone had flash-memory-used-as-swap die on them? The consequences would undoubtedly be dire. Also, has anyone measured flash memory access times to confirm or refute claims about slow access times? Are some types of flash memory better/worse than others in terms of access times?

I have installed Ubuntu 9.04
uname -r
2.6.28-11-generic
Checked cable/network with 386Box running Ubuntu 8.04 all OK. Could not get Realtek 8168 on mother board to work on Gigabyte H55M-S2H motherboard. I tried to install r8168 driver but no luck ... so I bought another Linux compatible card which turned out to be a RTL8139c (eth1) and the driver I am using on this is card is 8139too.
[Code]....
My preference would be to get the motherboard ethernet working but perhaps the card may be easier to get working. Anyway after searching the net for ideas and trying different things I've just about given up. I have reinstalled Ubuntu today so eth0 is back to using the r8169 driver. I'm no expert so my attempts at following other recipies have so far failed. From what I have read the 8139too driver should have worked with the RTL8139C chip so I have run out of ideas. I must be doing something wrong.

I had a problem with the install of Ubuntu 10.04 and 10.04.1 on a Dell Precision T3500. I used the 32bit live CD. I let the installer create the file systems and use the whole disc. The disc is was created as shown below. After the install button was pressed, the root file system was created and then the swap. When the installer went to mount the swap it complained there was not enough memory and failed the installation. I installed Ubuntu by manually making the swap file system smaller using gparted and assigning the / and swap to the file systems created by gparted.
Disk /dev/sda: 250.0 GB, 250000000000 bytes
255 heads, 63 sectors/track, 30394 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes

I have an existing Ubunto 9.10 install sitting on a 500 GB SATA drive that was sitting in my second SATA port. I'm trying to swap the internal HD out to a new system that has a 500 GB SATA drive with Windows 7 on it as the primary drive, in SATA port 0. When I configure BIOS to boot from my Ubuntu drive, I just get a flashing cursor on the screen and no Grub bootloader like I was before.
Does this mean Grub isn't on my Ubuntu drive? Should I install grub on both my Ubuntu drive's MBR AND my primary Windows 7 drive's MBR, or only one of the other. The instructions I've been reading don't specify which drive to reinstall Grub on and which drive I should boot from, so I'm confused. How do I get it so that Grub acknowledges my Windows 7 install on the primary drive?
