http://ubuntuforums.org – Hello All, This on behalf of someone I am trying to help with getting Ubuntu installed. Ubuntu 9.04 comes up nicely from the live CD, but it seems it cannot detect his hard drives, theres nothing under locations / computer. (It can see USB sticks, so it is working). It's a RAID setup, and the device shows up under device manager as: INTEL (IR) ICH8R (lots of numbers) DO SATA RAID CONTROLLER Are RAID arrays often a problem for Ubuntu? Is there a recommended way forward? It's clearly going to be tricky to install to an invisible disk! (Hardware)

Stories similar to [ubuntu] RAID issues with 9.04, disk not showing

Hoping someone can help...

Here is my setup:

4x Western Digital 1TB drives - 200GB RAID 0 (Windows 7 and Apps / Games) - 1.8TB RAID 10 (Data)

Both arrays use all 4 disks.

Ubuntu has its own 80GB drive (/dev/sde).

i can't install ubuntu 12.04 server on server in subject. I've created raid array from MegaRaid utility as RAID 1 but when i've tried to install into hard disk ubuntu doesn't detect any drive. Why?

raid controller is Intel Corporation 6 Series/C200 Series Chipset Family SATA RAID Controller

Thanks

I have Dell Poweredge T100 server with Dell SAS 6 and two hard disk on RAID 1.

Last week the server died including one RAID 1 hard disk. We sent the server for repair and the problem with PSU was fixed.

I want to set up software RAID-1 on my Ubuntu system, and found this example of an /etc/raidtab:

raiddev /dev/md0 raid-level 1 nr-raid-disks 2 nr-spare-disks 0 persistent-superblock 1 device /dev/sdb1 raid-disk 0 device /dev/sdc1 raid-disk 1

I would however like the path to the raid device to be /raid.

Hi,

I'm trying to get a windows 7 64bit-ubuntu 64 bit dual boot working onto a dell studio-xps-8100 with an EXISTING raid 0 array with 2 identical 2 tb hard drives with a ich8r/ich9r/ich10r/do/pch sata raid controller. I'm able to install ubuntu but not grub so I'm not actually able to boot into it.

I have a desktop with a hardware RAID built into the motherboard, (possibly called a FakeRAID, according to some research I have done.)

It was setup as a RAID 5, under Ubuntu 11.04, I attempted to upgrade to 11.10, and just ran into a hell storm of issues.

I decided to just unplug the 4 hard drives as part of RAID 5, and re-install Ubuntu 11.10 on a standalone IDE hard drive.

Now that I h

I'm at the end of my rope.

installed Server 11.10 on soft raid 1, then numerous problems booting first in degraded mode, then not at all. Try to reinstall, the whole array is gone.

I have a Proliant ML350 G8 with two SAS raid arrays currently set up - thereby maxing the default P420i raid controller. I need to set up a large video dump space in addition to this existing set-up (for non backed up, non-critical, temporary storage).

I had planned to just add a 2TB SATA disk and plug it into the motherboard.

I have a motherboard with an Intel ICH9R RAID chip. I have an existing RAID 5 setup over three disks which is NTFS formatted. I'm dual booting and I'd like to be able to access the RAID device in both Linux and Windows (and possibly OSX86, if I can ever get the darn thing to work).
