Fedora Installation :: Setup RAID 10 With Fedora 11 On Desktop?
Aug 11, 2009
I've been trying to setup RAID 10 with Fedora 11 on my desktop using this tutorial:[URL].. Everything has been going well, except when following the instructions and getting ready to format, it says I need to define / and boot partitions. This was never included in the instructions.
- LVM Volume Gropus
-- vg_jordan
--- fedoraRAID (type: ext4)
- RAID Devices
-- /dev/md0 (mountpoint/RAID/volume: vg_jordan ; type: LVM)

I'm attempting to install F13 on a server that has a 2-disk RAID setup in the BIOS. When I get to the screen where I select what drive to install on, there are no drives listed. The hard drives were completely formatted before starting the 13 installation. Do I need to put something on them before Fedora will install?

I have been battering with FC10 and software RAID for a while now, and hopefully I will have a full working system soon. Basically, I tried using the F10 live CD to setup Software RAID 1 between 1 hard drives for redundancy (I know its not hardware raid but budget is tight) with the following table;
[Code]....
I set these up by using the RAID button on the partition section of the install except swap, which I set-up using the New partition button, created 1 swap partition on each hard drive that didn't take part in RAID. Almost every time I tried to do this install, it halted due to an error with one of the raid partitions and exited the installer. I actually managed it once, in about...ooo 10-15 times of trying but I broke it. After getting very frustrated I decided to build it using just 3 partitions
[Code]....
I left the rest un-touched. This worked fine after completing the install and setting up grub, reboot in to the install. I then installed gparted and cut the drive up further to finish my table on both hard drives. I then used mdadm --create...etc to create my RAID partitions. So I now have

I have a Dell workstation, 2 HDD, HDD 1 setuped Red Hat 5.3 with LVM, and that HDD 2 is empty, not install RAID 1. And, I want to setup RAID 1 (hardware RAID)...but, have a problem. I don't want to lost data on HDD 1 when I setup raid, I try ghost or backup it, but when I restore, it error because LVM is setup on that.

I have had no problem installing Fedora OS on any of my Dell servers prior to this post. Anyway, I wouldn't call this a problem but recently, we bought another DELL server with Quad Core, 4GB, etc... AND this model has 2 swappable SAS Harddrives.
I wouldn't call myself an expert but then again I am not a newbie too. However, I have never setup any RAID before and now I am forced to setup RAID1 on this server. So, in a way, I am a newbie in setting up RAID
Would someone please point me in the right direction as I have no idea what I am supposed to do to setup the RAID. FYI, I will be installing Fedora 10 64bit on this server. I would appreciate if you can start from the very beginning, ie. partitioning, formatting the harddrives during OS installation, etc..

I'm looking to set up a bit of a home server, and am wondering about storage. What I'd like is something like RAID 6, which has good redundancy built-in, but with this being a home server, I'd prefer to start a little smaller and leave room to build it up in future. I'd been looking at commercial products like the 'drobo', which seems fairly ideal, but I'd really like to see if I can do it myself. I understand that throwing the RAID into an LVM will allow for some expansion, but the last time I checked, most RAID setups called for the same sized disks, or at least limited the array by the size of the smallest disk present.
What I'd like is the ability to build a basic framework with a few cheap disks, and then as things start filling up, to be able to add larger ones (perhaps eventually pulling out smaller ones as though they'd failed and replacing them with big ones)

I recently upgrade to Fedora 14 from 13. It was an in-place upgrade. I can't recall for sure, but I do believe I had these problems in F13 before the upgrade. The F13 install was from a Live CD. Anyway, I have a three drive RAID 5 array setup - 3x 750GB. For some very annoying reason, each time I reboot my F14 system, it hangs with an error about not being able to find a superblock on /dev/md126 and /dev/md127. I have tried to stop and remove /dev/md126 and /dev/md127 but they always seem to come back. I have also noticed in the output of fdisk -l that drives sda and sdd like to swap places sometimes for an unknown (to me) reason. Any other output that is needed, please ask. I recreated the array just yesterday with:
Code:
mdadm --create --verbose /dev/md0 --level=5 --raid-devices=3 /dev/sdb1 /dev/sdc1 /dev/sdd1
I would cat mdadm.conf in /etc, but I removed it previously to try to figure out the problem and it was not

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 looking to set up a server with attached mass storage device and tape autoloader to run linux. It's set up under Windows at the moment. Goal is to have users, connecting from individual workstations and laptops, backup their data to the linux server. On their personal machine, some users run linux, some MacOS, some Windows. I plan to set up the 5 500 GB drives as RAID5. I understand that if setting up as software raid the format is "physical volume for RAID". Under this setup, will Windows users be able to read/write and function as expected? I can't assume only linux user access.

I've tried to install Fedora 11, both 32 and 64 on my main machine.It could not install as it stops on the first install window. I've already filed a bug but really haven't seen any feed back yet.The bug has something to do with Anaconda and the Raid array but I really can't tell.
I have an Intel Board (see signature). I am running intel raid software under W7 currently.It works fine. But, I'm wondering, when I attempt to install F!!, is my current raid set-up causing problems? Do I need to get rid of the intel raid software and use a Fedor/Linux raid program to manage the raid array??

So I decided to build a server using two HDDs and after checking the net I decided to go with Software RAID.Before I mess around and go ahead and buy two 500 GB HDD, I decided to try it out first in virtual box.(my system is F13 64bit with 4GB)
I set up a virtual machine with 2 X 10GB HDD.Mount the live CD (f13 32bit).Run regular install > choose custom layout and do as follows: SDA & SDB will both have Software RAID 500 MB and another software RAID of about 9500 MB I will have md0 /boot (sda1 & sda2 = 500 MB) And another md0 having LVM group loaded with / + SWAP I choose to install boot loader on md0 the first time and I receive the following error when I boot from HDD: FATAL: INT18: BOOT FAILURE I tried installing boot loader on sda same thing.

When trying to set up desktop effects with Compiz I get this message: Accelerated 3D graphics is not available Desktop effects require hardware 3D support.
I have used Fedora 10 last year and the 3D effects worked fine. I have a Nvidia Geforce 6100 video. I also have another hdd on the PC with Mandriva 2010 which I use and the 3D compiz effects work fine. I'm running Omega 12. Isn't it Fedora 12 w/ codecs added? isn't video detection the same?

I am a Linux newbie. I am trying to see if it is possible to access a windows pc through some form of vpn/rdp setup. My machine is dual boot with Windows XP. On Windows XP, I am able to connect to my office via VPN client to connect to my office, then Remote Desktop to my local machine on the network.. Is there some way for me to do this with Linux? I find it really annoying to have to boot to Windows just to access my work pc.

My system includes two 120GB disks in fake raid-0 setup. Windows vista is installed on these.For Debian I bought a new 1 TB disk. My mission was to test Debian and I installed it to the new disk. The idea was to remove the disk afterwards and use windows as it was before. Everything went fine. Debian worked perfectly but when I removed the 1 TB disk from system grub will show up in boot in grub recovery mode.
Is my RAID setup now corrupted? Grub seems to be installed on the other raid disk? Did grub overwrite some raid metadata? Is there any way to recover the raid setup?

I just tried to install Fedora 12 x_64 on a machine that is currently running Fedora 11 x_64. It's a new machine for use as a server and is running a Phenom II 4 core on a gigabyte M/B - 4GB RAM, onboard ATI graphics, an Adaptec 5405Z RAID Controller that is in the 16 lane PCIe slot, and 3 SSD SATA dives in a RAID 0.I installed Fedora 11 x_64 on this machine just last week and it went perfectly smooth. The install recognized the video hardware, controller card and the RAID, installed correctly, boots fine, runs solid.When I attempt to install Fedora 12 x_64 on the same machine, it does NOT recognize the controller, nor the RAID and doesn't seem to like the video hardware. I stuck on a floppy drive and made a driver disk from the Adaptec provided Linux drivers, but the install fails to mount the floppy when I try to add the driver during boot from DVD - although it tries. (It's possible that my floppy drive and/or disks are too old to be useful. Seriously, loading drivers from a FLOPPY? Most computers don't even HAVE one any more.Sheesh...). The video also seems squirrelly and works better using the "simple" video drivers.
Anyone got any clues on this. It seems odd that the newer version works less well than the previous one.Maybe I'll try a different .iso - CDs or a live version or something just to check - and maybe try an install on a different machine. Yes, I put the install DVD through the self-test and it passed. I have tried 2 different copies and both fail.LATER - tried with live CD - boots OK, splash screen is OK, after bootup finishes it looks like maybe it's trying to start a different video driver - then the screen goes black and stays that way. Tomorrow I may stick in a discrete video card and see if that makes any difference.
Still Later: I have tried discrete video card, tried moving the RAID controller to the 4 lane slot, tried to install a driver from floppy (still no go) and have tried noprobe on boot command line. Although the "noprobe" got the video to keep going (albeit at a low resolution) it STILL refuses to see the RAID controller. The LED indicators on the RAID card SEEM to be indicating that the card locks up during Fedora 12 boot, but I haven't checked on that just yet. Fedora 11 continues to boot and run fine on the same machine - I'm running it right now. as I type this.Later yet: Ubuntu 9.10 86_64 that was released a couple weeks ago DOES, IN FACT see the controller and the RAID when I run the install process. Looks like Fedora 12 is badly broken after all. (Damn those even numbered releases anyway.....{;>D)=) Guess I'm going to be "stuck" with either Ubuntu or Fedora 11 unless a solution appears pretty soon. I have sent an inquiry to Adaptec, but I'm guessing they are going to say, "we don't support Fedora linux except Fedora 5 and Fedora 6" as those are the only drivers they seem to have available
Friday 11/20 - I've attached a SATA drive to the same computer. By using the "basic" video driver from the install DVD I am able to install F12 to the SATA drive without issue - it installs fine, boots fine, runs fine. However, it still will NOT see the RAID controller. I tried installing the driver .rpm from the disk that came from Adaptec, but the vanilla linux driver doesn't seem to be effective. So far, Fedora 12 continues to be a big FAIL! as far as this particular machine goes.

I have a spare machine running Windows 7 Pro x64 in RAID 0 (software RAID). I would like to install Fedora 13 x64 on a dedicated SATA HD (non-RAID) already in the machine but I'm unsure how Fedora's boot-loader will react to the RAID 0.

I want to install Fedora 10 but need to build RAID (bcraid) drivers so the installation will see my RAID array. I'm currently running Fedora 6 & thought this would be the process:
1) Install kernel source
2) Modify configuration to include bcraid drivers.
3) Build new kernel
4) Replace kernel in standard build with custom kernel or load driver during installlation
5) Install Fedora 10
I'm stuck on no. 1. When I tried to install the kernel source, there was some problem with "mockbuild" (wot dat?) which I think was a red herring but I now don't know what to do about these unsatisfied dependencies:
[root@fedora6 ~]# rpm -Vp ~/Desktop/kernel-2.6.27.5-117.fc10.src.rpm
warning: /home/nick/Desktop/kernel-2.6.27.5-117.fc10.src.rpm: Header V3 DSA signature: NOKEY, key ID 4ebfc273

As I understand, Fedora 12 sets up Intel ICH (when set in BIOS) as mdraid instead of dmraid.I would like to setup my 2 SATA hard drives so ultimately my /boot partition is RAID1, my / (ROOT) partition is RAID 1, and my swap is either RAID0, or fstab referencing 2 partitions on 2 of the drives, both set with pri=0 (which supposedly is equivalent to striping of RAID0, performance wise).
Assuming Fedora 12 uses mdraid for my configuration in either instance, am I better of enabling, or disabling the RAID mode in the BIOS? This system is strictly Fedora--no dual booting, no Windows. Any performance gains; reliability benefits between either scenario?It's a Intel P35 motherboard with ICH9R. Storage configuration is either "AHCI" or "RAID"
I ran into some strange issues with dropping drives with the RAID set on in BIOS. When it was set, that gave me two md devices of md126 (RAID0, swap) and 127 (RAID1 split between / and /boot). I think I had md126p1 for the SWAP, and md127p1 for /boot and md127p2 for / Within purely software, i have:
/dev/sda1 RAID
/dev/sda2 swap
/dev/sda3 RAID
[code]...
I suppose unless the BIOS enabled RAID is supposed to be faster, I'll stick with a purely software route and keep the BIOS set to AHCI.

I've been using Fedora and Ubuntu on a standard PC/laptop (one HDD) for some time, but just as a user. Recently I built a PC with Asus P5K WS motherboard with RAID adapter on board. I've got 5 750GB SATA drives, however hardware restrictions only allows me to create Logical Volume up to 2TB. SO I've created RAID 5 on 3 drives as SysVol and RAID0 on 2 drives for data.
Ran live CD and started to install OS. However I get to point, when system scans for storage devices. It detects smaller volume, but not the SysVol, I want to install the system on. It is offering me to install system on the smaller volume. I've deleted the smaller volume and left one RAID 5 volume and 2 drives. Again the same problem. System detects those 2 drives, but not the volume.
Is there any restriction in Fedora 12 allowing installation on certain LV? Or is it more HW problem?

I am doing a new install and have 4 drives (2x500Gb and 2x2Tb). What I want is the OS on the 2x500Gb and the data on the 2Tb drives. The idea is to make the 500's one RAID 1 set and the 2Tb a RAID 1 set. I think the installer is trying to build the RAID set for the OS but the root is looking like a RAID 0 rather than 1. Is there some way to specify?

I upgraded from F10 to F12 using preupgrade. The upgrade itself completed with no errors, but I'm unable to boot afterward.
Symptoms:...Grub starts, the initramfs loads, and the system begins to boot. After a few seconds I get error messages for buffer i/o errors on blocks 0-3 on certain dm devices (usually dm0 and dm2, but I can't get a shell to figure out what those are). An error appears from device-mapper that it couldn't read an LVM snapshot's metadata. I get the message to press "I" for interactive startup. UDEV loads and the system tries to mount all filesystems. Errors appear stating that it couldn't mount various LVM partitions. Startup fails due to the mount failure, the system reboots, and the steps repeat.
Troubleshooting done:...I have tried to run preupgrade again (the entry is still in my grub.conf file). The upgrade environment boots, but it fails to find the LVM devices and gives me a question to name my machine just like for a fresh install. I also tried booting from the full install DVD, but I get the same effect. Suspecting that the XFS drivers weren't being included, I have run dracut to create a new initramfs, making sure the XFS module was included. I have loaded the preupgrade environment and stopped at the initial GUI splash screen to get to a shell prompt. From there I can successfully assemble the raid arrays, activate the volume group, and mount all volumes -- all my data is still intact (yay!). I've run lvdisplay to check the LVM volumes, and most (all?) appear to have different UUIDs than what was in /etc/fstab before the upgrade -- not sure if preupgrade or a new LVM package somehow changed the UUIDs. I have modified my root partition's /etc/fstab to try calling the LVM volumes by name instead of UUID, but the problem persists (I also make sure to update the initramfs as well). From the device-mapper and I/O errors above, I suspect that either RAID or LVM aren't starting up properly, especially since prior OS upgrades had problems recognizing RAID/LVM combinations (it happened so regularly that I wrote a script so I could do a mkinitrd with the proper options running under SystemRescueCD with each upgrade).
I have tried booting with combinations of the rootfstype, rdinfo, rdshell, and rdinitdebug parameters, but the error happens so early in the startup process that the messages quickly scroll by and I just end up rebooting.
System details:4 1-TB drives set up in two RAID 1 pairs. FAT32 /boot partition RAIDed on the first drive pair. Two LVM partitions -- one RAIDed on the second drive pair and one on the remainder of the first drive pair. Root and other filesystems are in LVM; most (including /) are formatted in XFS.
I've made some progress in diagnosing the issue. The failure is happening because the third RAID array (md2) isn't being assembled at startup. That array contains the second physical volume in the LVM volume group, so if it doesn't start then several mount points can't be found.
The RAID array is listed in my /etc/mdadm.conf file and identified by its UUID but the Fedora 12 installer won't detect it by default. Booting the DVD in rescue mode does allow the filesystems to be detected and mounted, but the RAID device is set to be /dev/md127 instead of /dev/md2.
The arrays are on an MSI P35 motherboard (Intel ICH9R SATA chipset) but I'm using LInux software RAID. The motherboard is configured for AHCI only. This all worked correctly in Fedora 10.

I just bought two 320GB SATA drives and would like to install F11 with software RAID 1 on them. I read an article which explains how to install RAID 1, but it used 3 disks: one for OS and two clones. Do I really need a third disk to install RAID 1 configuration? If 2 disks is enough, then should I select "Clone a drive to create a RAID device" during F11 installation as explained here?

Currently running F10 on a RAID1 software raid array in Linux (not hardware or BIOS). I used the F13 install disk to boot and selected install/upgrade. Problem is that the Anaconda portion never sees the RAID device.
I tried passing the "nodmraid" argument to the kernel during boot. Other research suggested that the auto=md switch should be appended to the mdadm.conf file. No results from either solution.
Anaconda does not see the /dev/md0 or /dev/md1 and consequently it only offers an installation option.
What I would prefer is to upgrade.

I've been all afternoon trying to install Ubuntu Lucid on my fakeRAID 0 configured (2) HDDs and am unable to set GRUB up. The fake RAID setup is provided by Intel Matrix Storage Manager, it is correctly enabled and the BIOS is also correctly set up -- in fact, I've managed to install Windows 7 with no significant hitch. After struggling with partioning the drives (had to follow advice I found on a very helpful guide online [0]), creating the filesystems AND getting Ubuntu's installer to actually do what it is supposed to do, I now cannot seem to set GRUB up. My system, as it stands, is unbootable at all; via live CD only.
This is how the RAID0 dev is partitioned:
Code:
# fdisk -l /dev/mapper/isw_ecdeiihbfi_Volume0
Disk /dev/mapper/isw_ecdeiihbfi_Volume0: 1000.2 GB, 1000210694144 bytes

(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 have a fancy new Quad Core Xeon machine here that I'm trying to install F10 x64 on. The installation went fine. When it reboots the first time, though, I get the dreaded Error Loading OS.
So I dug up my bookmark of the awesome Grub HOWTO here and followed the steps to install Grub manually. Alas, I get the same result after installing it. Even tried doing a makeactive (hd0) just in case, but no luck.
I did more searching and searched for "raid install" but didn't find anything helpful. So here I am... hoping somebody has some insight.
