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).
Hi :)
I am using Zentyal v3 which uses Ubuntu 12.04.1.
I've already posted on the Zentyal forums [1], but I think its a Ubuntu issue, so I try to get a hint on these site :)
I have an existing lvm and raid configuration from the previous Zentyal version (Ubuntu 10.04).
After starting the 12.04 installer (no upgrade) - the partitioner has detected the raid and my lvm config (with curious names,
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 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.
So my computer has four 1.5 TB drives installed. Up until recently, these drives existed in two RAID1 configurations of 3 TB.
Recently I decided to create one large RAID5 device out of them instead.
So I have a system (a large instance running ubuntu-11.10 on Amazon EC2) where I've done something like
mdadm --create bigdata --level 0 --raid-devices=2 /dev/xvdb /dev/xvdc
I get a RAID device of two disks (ephemeral instance stores) at /dev/md/bigdata. Yay. reboot. I now have a RAID device of two disks at ip-10-811-498-737:bigdata. (ip anonymized).
This is kind of obnoxious.
Hey,
I have been losing quite a bit of sleep after a botched upgrade to 12.04. I gave up the upgrade and chose a clean install of 12.10. That went fairly well (apart from my nvidia card problems) however I have not been able to get my RAID array to work.
I have tried many things up until now but I have not been able to mount the array.
I just upgraded ubuntu from 12.04 to 12.10. Now in boot it won't start. My system has one hdd(where ubuntu is) and 4 1.5 tb sata drives in software raid5 configuration. In upgrade process it said some thing about raid. I think it tries boot from raid. Is there anything to fix this problem
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.
