Installation :: Hardware RAID 0 Still Show Up As 2 Drives / Cause Of It?
Jul 29, 2010My two 400G drives which have been added to a single 800G array (per fastbuild bios utility) still show up as two 400G drives in fdisk. Why is that?

Sep 16, 2009OK, I obviously did something wrong, but I dont think I did because i checked my kickstart file after installing.
When i do a df -h it shows that drives i set to 4096MB and 6144MB when I just installed the server, are showing as 3.9GB and 5.9GB respectively.
This is my first Linux install, does it not do the # x 1024 for partition sizes?
Ubuntu Installation :: Installing 9.10 On Drives That Used To Be In RAID
Jan 11, 2010I was recently given two hard drives that were used as a raid (maybe fakeraid) pair in a windows XP system. My plan was to split them up and install one as a second HD in my desktop, and load 9.10 x64 on it, and use the other for mythbuntu 9.10. As has been noted elsewhere, the drives aren't recognized by the 9.10 installer, but removing dmraid gets around this, and installation of both ubuntu and mythbuntu went fine. On both systems after installation however, the systems broke during update, giving an "read-only file system" error and no longer booting.
Running fsck from the live cd gives the error:
fsck: fsck.isw_raid_member: not found
fsck: Error 2 while executing fsck.isw_raid_member for /dev/sdb
and running fsck from 9.04 installed on the other hard drive gives an error like:
The superblock could not be read or does not describe a correct ext2
filesystem. If the device is valid and it really contains an ext2
filesystem (and not swap or ufs or something else), then the superblock
is corrupt, and you might try running e2fsck with an alternate superblock:
e2fsck -b 8193 <device>
In both cases I setup the drives with the ext4 filesystem. There's probably more that I'm forgetting... it seems likely to me that this problem is due to some lingering issue with the RAID setup they were in. I doubt its a hardware issue since I get the same problem with the different drives in different boxes.
Ubuntu Installation :: Creating RAID-1 With Only 2 Drives?
Jun 27, 2010I have recently installed a Asus M4A77TD Pro system board which supports raid.
I have 2 x 320gb sata drives I would like to setup raid-1 on. so far i have configured the bios to raid-1 for drives, but when installing Ubuntu 10.04 from the cd it detects the raid configuration but fails to format.
When I re-set all bios settings to standard sata drives ubuntu installs and works as normal but i have just 2 x drives without any raid options. I had this working in my previous setup but thats because i had the o/s on a sepreate drive from the raid and was able to do this within Ubuntu.
Ubuntu Servers :: RAID-1 OS Drives - Setting Up A Backup Procedure For The OS Drives
Jan 18, 2010I'm breaking into the OS drive side with RAID-1 now. I have my server set up with a pair of 80 GB drives, mirrored (RAID-1) and have been testing the fail-over and rebuild process. Works great physically failing out either drive. Great! My next quest is setting up a backup procedure for the OS drives, and I want to know how others are doing this.
Here's what I was thinking, and I'd love some feedback: Fail one of the disks out of the RAID-1, then image it to a file, saved on an external disk, using the dd command (if memory serves, it would be something like "sudo dd if=/dev/sda of=backupfilename.img") Then, re-add the failed disk back into the array. In the event I needed to roll back to one of those snapshots, I would just use the "dd" command to dump the image back on to an appropriate hard disk, boot to it, and rebuild the RAID-1 from that.
Does that sound like a good practice, or is there a better way? A couple notes: I do not have the luxury of a stack of extra disks, so I cannot just do the standard mirror breaks and keep the disks on-hand, and using something like a tape drive is also not an option.

Ubuntu Installation :: SSD Drive Not Detected - Zero Drives Show Up
May 15, 2010I can't finish installing Ubuntu 10.04. I have a Corsair Nova 128 GB solid state drive, the 128 GB model of this series, to be precise. I have an ASUS P5N-T Deluxe motherboard. It has a six xSATA 3 Gb/s ports NVIDIA MediaShield RAID controlelr on it. In Disk Utility, it shows up as nVidia Corporation MCP55 SATA Controller, using the sata_nv driver. I have the 128 GB drive plugged into one of these ports. I have disabled RAID completely in the BIOS.
When I boot the Live CD and run GParted, the drive shows up fine. I've got a 70.81 GiB NTFS partition (Windows 7), a 4.00 GiB swap partition, and a 44.43 GiB ext4 partition, onto which I had planned to install Ubuntu 10.04. I created the swap and ext4 partitions earlier, but at one point, that was unpartitioned space.
The problem is that when I run the Install app to install Ubuntu 10.04 on my SSD, when I get to step 4 of 8 (Prepare partitions), exactly zero drives show up. A while ago, I had a couple of Seagate 1.5 TB mirrored drives plugged into two of the ports, and they showed up fine, but no 128 GB SSD. In trying to troubleshoot this problem, I unplugged those and just left the SSD, and zero drives showed up. I disabled RAID in the BIOS, and it still doesn't show up. I moved the SSD from the port it was plugged into and plugged it into one of the ports that one of the 1.5 TB drives was plugged into. It still doesn't show up.
Nuts and bolts of it: Seagate 1.5 TB drive plugged into port: no problem. Corsair Nova 128 GB SSD plugged into port: doesn't show up. But again, only in the Install utility. In Disk Utility under SATA Host Adapter/MCP55 SATA Controller, I see 128 GB Solid-State Disk/ATA Corsair CSSD-V128GB2 listed plain as day. In GParted, I see a 119.24 GiB /dev/sda device with the partitions I've created on it plain as day. I can pull up a terminal and mount /dev/sda3 /mnt/ssd without any problem and access files on it. But for whatever reasons, the Install program and only the Install program can't see it. I'm dead in the water. Obviously, I can't use Ubuntu if I can't install it. What can I do to get this disk drive detected?

Ubuntu Installation :: RAID / LVM Cmds To Migrate To Larger Drives?
Sep 27, 2010how to migrate my whole server to larger hard drives (i.e. I'd like to replace my four 1TB's with four 2TB's, for a new total of 4TB instead of 2TB)... I'll post the output from everything (relevant) that I can think of in code tags below.
I'd like to end up with much larger /home and /public partitions. When I first set up raid and then LVM it seemed like it wouldn't be too hard once this day arrived, but I've had little luck finding help online for upgrades and resizing versus simply rebuilding from a failure. Specifically, I figure I have to mirror the data over to the new drives one at a time, but I can't figure out how to build the raid partitions on the new disks in order to have more space (yet mirror with the old drive that has a smaller partition)... don't the raid partitions have to be the same size to mirror?

General :: Ubuntu 9.10 Installation Insists For RAID Hard Drives
Jan 29, 2010So windows wouldn't recognize my drives as a raid setup, so I disabled it and switched to IDE, now Ubuntu 9.10 installation will only recognize my drives as RAID. I have and ASUS M3A32-MVP Deluxe Series motherboard, it has 4 sata connectors and 2 marvel controlled sata connectors. In the 4 sata connectors I have my 2 wd 500gb hds, my dvd burner, and my external usb, esata slots. In the marvel controlled sata connector I have a wd 160gb hd. Originally when I built the computer I wanted a raid setup with the 2 500 gb hds.
But windows wouldn't recognize the raid set-up and wouldn't boot properly. So I said screw it and removed the raid and set all the drives to IDE. Then, when I tried to install Ubuntu 9.04 it would only recognize my 2 500 gb hds as raid. Gparted recognizes the drives as both raid and IDE. Eventually, after a day or two of praying and messing around the installer recognized both drives as raid and IDE. A couple months later here I am trying to install Ultimate Edition 1.4.
Debian Installation :: Use The PC As A File Server With Two Drives Configured As A RAID 1 Device?

Fedora Installation :: Software RAID With Advanced Format WD-EARS Drives?
Dec 31, 2010My System Intel Core Duo E5300 Mobo - Gigabyte G31M-ES2L 1GB DDR2 800MHz RAM 4 x WD20EARS HDD I have been trying to install Fedora or Ubuntu for over a week. I thought it would take an hour and i would be away. I have been trying to install using the mdadm Software RAID feature. Everytime it takes about a day to format the drives and then i get an installation error. The drives state they are ready to use as is on any operating system other then WinXP, but this does not appear to be the case.
I am very new to Fedora... I have been doing some reading.[URL].. That information has been promising. I have been able to get into Fdisk off the live CD but i can't figure out how or if it is possible to do what i want it to.
Has anyone had any luck getting these drives to function correctly in a software RAID? I have had good luck with WD drives in the past and just assumed these drives would do what i wanted to but alas i have been proven wrong.
The partitions i wanted was...
- A 2GB swap parition
- A 10 GB RAID 1 partition for Fedora
- The remaining space as a Raid 5 for files.
Am i just banging my head against a wall here, or is this possible.
Fedora Installation :: Using The F10 Live CD To Setup Software RAID 1 Between 1 Hard Drives For Redundancy & Fstab
Apr 15, 2009I 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;

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

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

Fedora Installation :: Raid On Dell R210 - Install Driver - Sees 2 Separate Drives?

Ubuntu :: Intel RAID Controller - Showing 2 Drives?
Apr 24, 2010I shall start off by saying that I have just jumped from Windows 7 to Ubuntu and am not regretting the decision one bit. I am however stuck with a problem. I have spent a few hours google'ing this and have read some interesting articles (probably way beyond what the problem actually is) but still don't think I have found the answer.I have installed:
Distributor ID: Ubuntu
Description: Ubuntu lucid (development branch)
Release: 10.04
Codename: lucid
I am running the install on an old Dell 8400. My PC has an Intel RAID Controller built into the MB. I have 1 HDD (without RAID) (which is houses my OS install) and then I have 2 1TB drives (These are just NTFS formatted drives with binary files on them nothing more.) in a RAID 1 (Mirroring) Array. The Intel RAID Controller on Boot recognizes the Array as it always has (irrespective of which OS is installed) however, unlike Windows 7 (where I was able to install the Intel RAID controller driver) .Does anyone know of a resolution (which doesn't involve formatting and / or use of some other software RAID solution) - to get this working which my searches have not taken me too?
