how do i install a linux distro that doesnt natively support Intel fakeraid, using dmraid and a livedisk. the raid is already setup, its just that backtrack cant find it because it doesnt have the right software.
View 2 RepliesI have two Ubuntu 8.04 servers currently. I've purchased some 500 GB hard drives and a RAID cage just yesterday and plan to change my current servers to using RAID1 with the hard drives. Much like everyone else, I have the nVidia RAID built onto the motherboard that I plan to use. There are many how-to's out there on how to setup RAID using dmraid during the install process - but what would a person do if they are simply changing over to a RAId system? I installed dmraid a few days ago on the server. It seems that even though I have RAID shut off in the BIOS, it saw the one and only drive as a mirrored array. When I rebooted today, the server would not start; it had ERROR: degraded disks.. bla bla. Then Grub tried to start the partition based off the UUID of the drive (which was not changed) and it said "device or resource busy" and would not boot.
This problem was corrected by going into the BIOS and turning on RAID. When I rebooted, the nVidia RAID firmware started and said degraded. I went in there and deleted the so-called mirror keeping the data intact. Rebooted, disabled the RAID feature in the BIOS and then the server loaded normally with a message "NO RAID DISKS" - but at lest it did boot! So this leads me to believe that trying to turn on a RAID-1 array (just mirror between two disks) may be a challenge since I already have the system installed. I will be using Partimage to make an image of the current hard drive and then restore it to one of the new drives.
The next question is - is it a requirement that dmraid is even installed? While I understand that the nVidia RAID is fake-raid - if I go into the nVidia RAID controller and setup the mirroring between the two disks before I even restore the files to the new disk, will both drives be mirrored? However, I do think that I'd probably have to have dmraid installed to check the integrity of the array. So, I'm just a bit lost on this subject. I definitely do not want to start this server over from scratch - so curious to know if anyone has any guidance on simply making a mirrored array after the install procedure, what kind of Grub changes will be needed (because of the previous resource is busy message), and whether installing dmraid is even a requirement.
1) Use INSSERV to start DMRAID
2) Use MKINITRD to create a new INITRD file which loads the DMRAID module.
Neither solution showed any detail of how to accomplish this, and which files to edit or what order I should use to tackle either. With the second solution, I have another SUSE 11.2 installation on another hard drive. Would it be ok to boot into that and create a new INITRD with DMRAID activated, or would it be better to break the RAID-set boot into one of the drives and create INITRD for that RAID 1 system, then recreate the RAID-set? The only issue I would see is that fstab, device mapper and grub would need the new pdc_xxxxxxxxxx value, which can be changed from the second installation.
My system is:
Asus M4A78T-E with fakeraid SB750 controller
AMD Black Edition - AMD Phenom II X4 3.4 GHz Processor
2 x Samsung 1TB drives
Suse 11.2
I have Windows XP on another hard drive purely for overclocking and syncing the 1TB drives, but I can't actually boot into the SUSE system until this issue is sorted out.
I've googled my problem but I'm not sure I can find an answer in layman's terms. So here's my noob, simple question, please answer it in semi-noob-friendly terms I've been trying to install ubuntu for a while on my desktop pc. I gave it another go with 10.10 but I always have the same problem:
I've got two raid sets connected to an ich10r chip and they work fine in windows (2 samsung 1to + 2 raptors 75gb). Upon installation, dmraid only sets up the first raid set (Samsung array) but not the second one (Clean raptors intended for ubuntu). I don't have any other installation option, all my sata connectors are unavailable. So, is there a manual install solution? Can I force dmraid to mount the second raid set and not the first one? I think I read somewhere that this was a dmraid bug, but I can't find it anymore.
i have 2 partitions on dmraid. I am not able to configure them to mount with yast; yast partitioner gives an error stating that it can't mount a file system of unknown type. I am able to start the dmraid devices manually and mount them manually.
See bug:

i ve run into problems while installing 11.3 x64. Installer stops at search for linux partitions... to solve it i ve had to go back to 11.2. Anyway, i have installed 11.3 on another hdd (3hdds in raid 5 had to be disconnected). When i go into partitoner (11.3) and device graph, i see two of three raid hdds ok with sda1, sda2.... but the third one is without any partitions./ if i do the same in 11.2 all three hdds are with all partitions in that graph. Anyone know the solution except not installing 11.3? .)
View 2 Replies View RelatedI'm pretty new to FakeRAID vs JBOD in a software RAID, and could use some help/advice. I recently installed 11.4 on a brand new server system that I pieced together, using Intel RAID ICH10r on an ASUS P8P67 Evo board with 2500K Sandy Bridge CPU. I have two RAIDs setup, one RAID-1 mirror for the system drive and /home, and the other consists of four drives in RAID-5 for a /data mount.
Installing 11.4 seemed a bit problematic. I ran into this problem: [URL]... I magically got around it by installing from the live KDE version with all updates downloaded before the install. When prompted, I specified I would like to use mdadm (it asked me), however it proceeded to setup a dmraid. I suspect this is because I have fake raid enabled via the bios. Am I correct in this? Or should I still be able to use mdadm with bios raid setup?
Anyways, to make a long story short, I now have the server mostly running with dmraid installed vice mdadm. I have read many stories online that seem to indicate that dmraid is unreliable versus mdadm, especially when used with newer SATA drives like I happen to be using. Is it worth re-installing the OS with the drives in JBOD and then having mdadm configure a linux software raid? Are their massive implications one way or another on if I do or do not install mdadm or keep dmraid?
Finally, what could I use to monitor the health and status of a dmraid? mdadm seems to have it's own monitoring associated with it when I was glazing over the man pages.

I have a Dell Inspiron 530 with onboard ICH9R RAID support. I have successfully used this with Fedora 9 in a striped configuration.Upon moving to Fedora 13 (fresh/clean install from scratch), I've noticed that it is no longer using dmraid. It now appears to be using mdadm. Additionally, I need to select load special drivers (or something close to that) during the install to have it find my array - which I've never had to do before with F9. While the install appears to work ok and then subsequently run, my array is reporting differences .. presumably because it is trying to manage what mdadm is also trying to manage. More importantly, I can no longer take a full image and successfully restore it as I could with the dmraid F9 install. Is there anyway to force F13 to use the dmraid it successfully used previously?
View 1 Replies View RelatedI have a truecrypt partition on an nvidia fakeraid raid0.ore there is no data recognizeable to ubuntu's kernel on startup and I think it is causing a big slowdown for me every time I boot up, which takes over ten minutes every time. Attached are bootchart results.What I would like to do is know how to remove dmraid from the startup process. I can't find any scripts in /etc/rc*.d and all of the information I can find on these forums is about how to enable dmraid on boot, not disable it.
Manually using dmraid takes nearly no time at all, which is what I did before this kernel upgrade since ubuntu didn't put dmraid in the startup process. I can't see why it takes dmraid ten minutes to detect raid devices now! The only clue I can see is that in the startup process with the splash screen disabled it talks about examining inodes on both drives in the array and then goes on to spit out stuff about raid 0, raid1, raid2, raid3, raid4 and on and on so it seems like it is loading raid arrays that don't exist and never have.If any bootchart gurus have any advice, please feel free to throw me a bone, I am in fear of restarting!edit: for some reason ubuntuforums shrank my images so that they are unreadable by anybody except those with a large projector.
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
