I've got a couple of boxes (one linux and one Win Vista) that I want to enable the hardware RAID 1 (mirrored drives). I've not worked with RAID before. I don't really know much about RAID, but from what I've gathered from google, it seems like I may have to enable the RAID first in the BIOS and then reinstall. Is that correct or is there a way to enable the onboard RAID without reinstalling? I was hoping to clone the drive with dd and then enable RAID 1 in the bios and viola! Since one of the machines is my parents' (the Vista box), I'd prefer to do something non-destructive. I may just setup a backup mechanism for them where at least they have the data files backed up to the other drive. If I have to reinstall mine (Debian Lenny), I may bite the bullet and do the reinstall.
I am looking to convert a raid 1 server I have to raid 10. It is using software raid, currently I have 3 drives in raid 1. Is it possible to boot into centos rescue, stop the raid 1 array. Then create the raid 10 with 4 drives, 3 of which still has the raid 1 metadata, will mdadm be able to figure it out and resync properly keeping my data? or is there a better way to do it?
Here is my system: I have dell poweredge 1950 PERC 6 with 300 GB raid system. It has two disks of each 300GB RAID mirrored system. I have few applications and data that reached around 280GB. As you know, poweredge 1950 we can have only two disk.
They are not mission critical. Hence, I wanted to remove the raid system and use as a non-raid system. By doing it, The applications and data can grow upto 600GB. I do not want to loose the data and setup. I am not so clear about RAID system and its conversion.
I kept my movies on a 2 drive software raid1 mirror, but now I changed my mind about needing a raid and pulled one of the drives for another use. Can I convert the remaining raid drive back to a regular single drive and keep the data in place? Can I change the raid partition back to regular partition and be able to mount it?
If I have a windows installed in raid-0, then install virtualbox and install all my linux os,s to virtualbox will they be a raid-0 install without needing to install raid drivers?
I was recently requested to try and convert a running system to RAID level 1. I did not succeed in this task. However, I am still interested in accomplishing this task in a test environment.What I did was create a RAID device with a device missing e.g.
Once the RAID was up and running I created the /etc/mdadm.conf file so that it would activate the RAID device on boot. Once the device was created I copied all the data from the running root filesystem to the /dev/md0 device. The only directory that I didn't copy was the /proc directory. When I rebooted the machine I had a kernel panic and the system couldn't find /dev/root. I would greatly appreciate it if someone could provide some information/tips regarding the problem.
I'm trying to use convert, I have installed the imagemagick. I use this line:convert *.jpg test.pdf but I'm only able to convert to pdf 1 single jpg file, not multiple files at once. When there's more than one file, I get the following error: Segmentation fault
I wanted to install this package to convert one Unix book into pdf. Since I have not set up the internet in the debian, I download the .deb files in winxp and transfer these files to my pen drive and then access it in the Debian. So I got all the 'depends' packages for the chm2pdf from the Debian Packages site and tried to install. Console was still asking for more dependencies. If I have got all the 'depends' packages which are required for chm2pdf, then why does it give problems ?
So I didn't notice when I setup my CentOS 5.5 server that I left / as RAID 0 on md1. All the rest are RAID 1. Is there a way I can modify the array to RAID 1 without a risk of data loss? I'm glad I caught this before I setup any other services. I've only setup smb so far...

I am running single drive Ubuntu server 9.10 with a lot of software. Now I want to add one more disk (same size and type) and to convert this to RAID 0 without need of reinsallation. Is it possible and if yes how? I didn't find nothing for RAID 0. It sounds simple, but probably is not.
I wish to install Linux Mint 11 with RAID 1 for my /home. I was wondering if I can install RAID 1 during the installation from the Live CD.I have managed to set up RAID from the Live CD and install Linux Mint 11 to it, but on reboot it will not recognize the RAID volume as mdadm is not installed. Can I install RAID drivers from my Live CD onto the installed Mint using chroot and get Mint to recognise the volumes on reboot? Is there a better alternative?
I know this would be a trivial exercise using the Alternate CD in Ubuntu but Mint does not have an Alternate CD (at least that I aware of).
<silent-> my company gave me a small project do in linux , i need you to give me some advice. <silent-> basically its will be a file server and something like 5 users will need to
Could any RAID gurus kindly assist me on the following RAID-5 issue?I have an mdadm-created RAID5 array consisting of 4 discs. One of the discs was dropping out, so I decided to replace it. Somehow, this went terribly wrong and I succeeded in marking two of the drives as faulty, and the re-adding them as spare.
Now the array is (logically) no longer able to start:
mdadm: Not enough devices to start the array.Degraded and can't create RAID ,auto stop RAID [md1]
Code: mdadm --create --assume-clean --level=5 --raid-devices=4 /dev/sda2 /dev/sdb2 /dev/sdc2 /dev/sdd2 As I don't want to ruin the maybe small chance I have left to rescue my data, I would like to hear the input of this wise community.
If I install the factory release now, can I easily convert my system to a normal 11.3 point release later, after 11.3 is out? If so, how would I do it? (11.2 has an issue that affects me. It's fixed in 11.3 already, so I have to use 11.3 if I'm going to use openSUSE.)
Installing Ubuntu 10.10 desktop.on a Highpoint rocketraid 2642.Installing Ubuntu, it does not find the drive?How do I install the drivers to install and boot after the installation from the raid drives?
I have Ubuntu 9.04 and just installed Sound Converter. I am trying to convert a bunch of .ogg files to mp3 to play on my iPod and it's not working so well. In the Sound Converter options I have is set to convert to high quality mp3. I choose the folder that the files are in and after a moment (slow laptop) Sound Converter populates, I hit 'convert' and it shows that the conversion completes in two seconds. All that it did was create the new folder structure of artist/album but there is nothing in there. Not sure what I am missing. I used Sound Converter before and it worked fine.
I cannot install 11.3 on a machine with an intel raid controller I have tried with raid 1 using the card and then setting the disks to individual raid 0 and letting suse raid them. With the card doing it the machines crashes as soon as it tries to boot the first time, with suse doing the raid I just get 'GRUB' on the screen It seems a lot of people are having similar problems, does any one have any pointers. 11.2 installs fine. I would try and do a bug report but every time I go to the page it's in Czech
I was writing a Slackware script to install OggConvert when I realized I could not find a way to install it. So if anyone know the command I would love to hear it. Not just use it, but to install it. I know it is written in python so I hope it can be installed.
I have a lot of .flac files downloaded from several sites. Most of them come with a .cue file, and the .jpg with the cover, etc. It seems it is the intention of the uploader that one rebuilds the original CDDA. However, if I had a stand-alone CD/DVD player with flac I would hardly see the point of converting the flac to cdda. Furthermore, I could even play the flacs with a software player although, in this case, the audio quality would not be so good due to the noise picked up by the signal from the PC digital circuits.
I am trying to make a liveUSB(my DVD drive run out monthes ago), I use this iso image: openSUSE-11.1-KDE4-Reloaded-LiveCD.x86_64-4.3.1-Build4.1.iso I just cp the file in the iso into the usb, and cp the L : ootx86_64loader*.* into my usb, mv the isolinux.cfg into syslinux and run with syslinux command to install the bootloader. and boot with my usb drive,get Error: ..

I have a raid5 on 10 disk, 750gb and it have worked fine with grub for a long time with ubuntu 10.04 lts. A couple of days ago I added a disk to the raid, growd it and then resized it.. BUT, I started the resize-process on a terminal on another computer, and after some time my girlfriend powered down that computer! So the resize process cancelled in the middle and i couldn't acess any of the HDDs so I rebooted the server.
Now the problem, the system is not booting up, simple black with a blinking line. Used a rescue CD to boot it up, finised the resize-process and the raid seems to be working fine so I tried to boot normal again. Same problem. Rescue cd, updated grub, got several errors: error: unsupported RAID version: 0.91. I have tried to purge grub, grub-pc, grub commmon, removed /boot/grub and installed grub again. Same problem.
I have tried to erased mbr (# dd if=/dev/null of=/dev/sdX bs=446 count=1) on sda (ide disk, system), sdb (sata, new raid disk). Same problem. Removed and reinstalled ubuntu 11.04 and is now getting error: no such device: (hdd id). Again tried to reinstall grub on both sda and sdb, no luck. update-grub is still generating error about raid id 0.91 and is back on a blinking line on normal boot. When you'r resizeing a raid MDADM changed the ID from 0.90 to 0.91 to prevent something that happend happened. But since I have completed the resize-process MDADM have indeed changed the ID back to 0.90 on all disks.
I have also tried to follow a howto on a similar problem with a patch on [URL] But I cant compile, various error about dpkg. So my problem is, I cant get grub to work. It just gives me a blinking line and unsupported RAID version: 0.91.
How long does hardware Raid card (raid 1, 2 drives)take to mirror a 1 TB drive (500gb used)?Is there a general rule of thumb for this?4 hours? 12 hours? 24 hours?
I am trying to connect a RAID Box to the server via LSI 8880EM2 RAID controller.The raid box is FUjitsu Externus DX60 with raid 1 configured.The server is Fujitsu Primergy SX300 S5 with LSI 8880EM2 RAID card.The external raid box is being recognised by the raid controllers bios.
The server runs CentOS 5.5 64bit. I have installed the megaraid_sas driver from LSI website and MegaCLI utility but CentOS still fails to see the box.MegaCLI utility, when launched from CentOS, recognises the raid box, CentOS does not(no mapping being created in /dev).
I have also tried to create a logical RAID0 HDD on one physical HDD(as seen by MegaCLI) with MegaCLI utility in CentOS.The result was success and the new logical drive could have been used, but when restarting the server, the controllers' bios fails with an error (not surprised(one logical RAID0 on one physical HDD)) and configuration is being erased.
Has anyone tried connecting 8880EM2 controller to a raid box with raid configured on the box, running it all under CentOS and what were the results.
I installed ubuntu 10.10 using wubi installer, on win 7 64 bit system. how can I migrate from wubi install to standard install. I want to get rid of issues like free disk space and suspend/hibernate not supported in wubi ubuntu. Will LVPM help. I saw on the page it says that it does not supports wubi 10.04. Not sure what version I have, just installed the latest from ubuntu's site.
I have installed Ubuntu on my m1530 since 8.04 and currently dual boot Win7 and 10.10. I would like to dual boot on my PC, but I have run into a problem. I am not a pro at Ubuntu, but this problem I can not solve by reading forums like I have in the past.
I realize this is a common problem, but I have noticed people having success.
I have a M4A87TD EVO MB with two Seagate drives in Raid 0. (The raid controller is a SB850 on that MB) I use the raid utility to create the raid drive that Windows7x64 uses. I have 2 partitions and 1 unused space. Partition 1 is Windows, partition 2 is for media, and the remaining unused space is for Ubuntu.
I am running ubuntu-10.10-desktop-amd64 off a Cruzer 16GB flash drive that was installed via Universal-USB-Installer-1.8.1.4.
My problem like so many others is that when I load into Ubuntu, gparted detects two separate hard drives instead of the raid. I read that this is because kpartx is not installed on 10.10. I then went in LiveCD mode and downloaded kpartx from Synaptic Manager. Gparted still reported two drives. I opened terminal and run a few commands with kpartx. I received an error. (Forgive me I didn't write it down, but I believe it said something about a communication error. I will try again later and see.)
Currently I am reflashing the Cruzer with a persistence of 4GB. I am not familiar with this process, but I understand that my LiveCD boot will save information I download to it. I decided to try this method because I was going to install kpartx and reboot to see if this made a difference.
I am looking for any suggestions on a different method or perhaps someone to tell me that the raid controller or some hardware isn't supported. I did install ubuntu-10.10-alternate-amd64 on my flash drive, but fail to get past detecting my CD-ROM drive since it's not plugged in. If this method is viable, I will plug it in. I also watched the ..... video were a guy creates Raid 0 with the alternated CD, but it wasn't a dual boot and didn't use a raid controller from a MB.
