I had windows and ubuntu for some time, the other day I had an issue with (msconfig). The easiest way to fix it is to fresh install windows. So I wanted to boot into ubuntu, take my windows files and toss them onto a external drive. So this is were I need help. I have 3 hard drives, 2 internal and 1 external. The 2 internal drives are 2 500 gig WD's in raid0. I can not find out how to retrieve my data from these drives at all. I can get the partition manager to tell me I have them, but I can not find them anywhere let alone get data off. And I have my work for my 10 page research paper on there and I should be working on it but have not been able to retrieve the work and put it on my laptop.
I currently have two hard drives, with my root partition configured in RAID0. I'd like to add two additional hard drives, and include them in my RAID0 array. I need to recreate the array to do this, so I'd like to copy everything off of the existing array, add the drives, build the new array, and copy everything back. I have an external hard drive with four times the capacity of my current array. What would be the best way to copy this data so that nothing is missed, so I can just copy everything back and boot back up? dd, image the entire root partition, mount it after creating the new array, copy everything back (at the filesystem level) dd, image the entire root partition, write it back out to the new array, I'm not sure how this would work, because the partition will be the wrong size, I don't know much about dd. rsync, just rsync everything on root over to the external something else? I plan on booting to a live CD and mounting my current array there, so I won't be working on a live filesystem.
I am trying to install Ubuntu 10.10 using Wibu inside Windows and installation looks good without any problems but when I select Ubuntu in Boot POST menu after I see Ubuntu Desktop I see error it's saying that Root directory is not specified and there is OK button and if I press it I see same message. only way to get out is to click restart in top right corner. My Windows installation is on RAID0 SSDs and I actually tried to install it on same partition as windows and even tried to install on NEW unallocated and freshly formatted partition. Nothing works. I am thinking to install it from Live CD however in advance formatting on let's say 20gb of space what do i assign ? Like how do I partition it like root directory and swap and other partition i ll need. Like can you specify all I think 3 different partitions I'll need and how much space to allocate for each on let's say 20GB of space.
I remember I had a choice "Use all free space" and it was soo simple I could have windows and some unallocated space on hard drive and Ubuntu would of use it . Now I don't see this option. I see use entire disk ...or advanced where You have to create on unallocated space all parts of partitions needed that's

I administer a small network of computers connected to a windows 2003 server. The machines Dual boot Windows XP and CentOS 5.
My question is this. The machines are being upgraded to HP Z800 workstations. These workstations come with 2 1TB drives setup on a hardware RAID0. Can I install Linux on these machines, using the RAID0? Can I do an install as if it was just one hard drive? The machines came with Windows7 and I'd like to keep it intact including the RAID0. Can I do the install where it resizes the partition, adding the linux partition to the "drive".
If I can't use the existing windows RAID0 to install CentOS I was thinking of just installing another hard drive in the machines for it. This brings up another question, what would happen if I moved my Linux drive from one of the old workstations and put it in the new workstation, would it boot? I know windows wont boot like this because of the hdd controller drivers and I have a sneaky work around for this anyway but am not wanting to transfer the windows installation.

Last week I installed Ubuntu 10.10 on my system in dual booting. I had installed succesfully both but unable to see data files from windows OS. Though I have excercised the options in various resources available on internet/blogs. System takes about 03 hrs during installation process. I am also unable to configure Thunderbird.

I used Palimpset to set up a RAID0 arry using the beta of 10.04. I, being the neat freak that I am, like to do a clean install between betas and final releases. So I backed up all my photos and such to that RAID array (this is on my home server/desktop, by the way) and reinstalled (using the final Ubuntu Server 10.04 disk). When I was re-installing, I stupidly created (but didn't format) a new RAID array over the one with my data on it. Now I'm back on the final Ubuntu Server 10.04, and palimpset recognizes that theres a RAID array, but says its unformatted.
I upgraded my 9.10 installation to 10.04 and decided to try out btrfs on a some spare drives in the system.sudo mkfs.btrfs -m raid0 /dev/sdb /dev/sdc /dev/sddthe only way the system sees the btrfs array is by running btrfsctl -a and then mounting /dev/sdc. but that has to be done in userland, not at boot. if i try to mount it via fstab, ubuntu won't load because it can't find the mount point./dev/sdc /Images atasum,thread_pool=128,compress,rw,user 0 0so where am i going wrong? I tried mounting via the UUID also but that didn't seem to work for me either.
I just encountered a huge problem with my PC. It's a Sony VAIO VGC-RC210G with the first two HDDs in a RAID0 configuration. Windows Vista is installed on the RAID and Kubuntu on another HDD.We had a power outage yesterday and the PC was powered on. Vista wouldn't boot, something which I traced to crcdisk.sys (stupid f***ing CRC check)
How do i create a raid0 array of these drives? On each drive i have got a partition whose size is 160GB and formatted to type fd (Raid Autodetect) i have tried the following:
Code: mdadm --create /dev/md0 --level=0 --raid-devices=3 /dev/sdb1 /dev/sdc1 /dev/sda1 mkfs.ext4 /dev/md0 mount /dev/md0 /media/raid but for some reason it doesnt work.
Looks like Grub2 on my new installation of Ubuntu 9.10 is not picking up a Windows 7 installation on a RAID0 array (using the built-in RAID software from my Asus P5Q-Deluxe)
Here are the results of the boot info script:
Code: Boot Info Script 0.55 dated February 15th, 2010 ============================= Boot Info Summary: ============================== => Grub 2 is installed in the MBR of /dev/sda and looks for (UUID=43b4cb20-dfea-4513-80e9-54d066107c71)/boot/grub. => No boot loader is installed in the MBR of /dev/sdb
I ran into this and found a non-trivial solution so I thought I'd share in case anyone else ran into it.I have two 200GB drives so I thought I'd install my system with RAIDed partitions for /boot, / and /home. I would use RAID1 for /boot and /home because GRUB2 can load the kernel from a RAID1 and I thought the extra reliability for /home would be nice. (I may second guess /home on RAID1 once I get to test performance.) I chose RAID0 for / to provide faster application loading.I prepared the drives using a Live CD because I'm not confident that I can do what needs to be done during installation.First I partitioned the drives as:
Code:
hbarta@olive:~$ sudo fdisk -luc /dev/sda Disk /dev/sda: 200.0 GB, 200049647616 bytes 255 heads, 63 sectors/track, 24321 cylinders, total 390721968 sectors Units = sectors of 1 * 512 = 512 bytes
[code]....
At this point I could restart and boot from the system hard drives and proceed with configuring my system. I'm not positive that it is necessary to add the modules to /etc/initramfs-tools/modules but I do know that alone is not sufficient. An earlier attempt was to install grub (install-grub /dev/sda; install-grub /dev/sdb) within the chroot and I found that also was not sufficient. I have not listed it above because I think it was not necessary. But on these two issues, I'm not going to reinstall again from scratch just try...

Another possibility is to install using the Alternate CD. I did not try that but it may provide better RAID handling. Last week I installed 10.04.2 LTS Server to a RAID1 and it did not experience this problem. However I do not know if it is RAID in general or RAID0 that led to the issues I encountered.
I have ubuntu server 8.04 installed. It uses software raid0 (mdadm, two hard disks: sda and sdb). The server crashed after power failure. When trying to boot I get the following messages:
I'm an experienced PC technician running a slackware 13.1 distro on a server at home. I've currently got 2x 1TB drives in the box allocated as raid1 for the OS and everything I want to run on the machine. I'd like to think my question/needs are fairly straight forward, I am buying 2x 2TB drives to add to this machine as it serves as a NAS box for one of its roles. I'd like these in raid0 as the data that would be going on it is not that important to me. The question is, after adding the new drives to the system, once I boot up, what do I need to do to the system to get the drives added and working sucessfully as a single raid0 volume that I can then samba share out to my network. To clarify, I understand a little of mdadm as I've used it to raid1 my existing setup when I installed, and I'm fine with the samba bit after.
When I installed Ubuntu, it created a folder called 'ubuntu' on my hard drive. Is there a way to recover my data from this folder and use it with a newer version of ubuntu. I can't access Ubuntu on my computer. It boots straight into Windows.
I have a full Ubuntu 9.10x64 install on an external hard drive and I was recently asked by a friend who has a laptop running 32 bit vista if I might be able to help him in recovering anything from pictures to Quick Books files. He believes the hard drive is corrupted. His laptop is an HP with less than 2 gigs of ram, and he is not sure about the motherboard/chipset. It may or may not support x64. He went out and bought an iMac the other day so he wouldn't need to deal with not having a working computer.
Now I have 2 questions. The first being, I am wondering if my x64 install will still be able to run if I tried booting to it from his computer in the event that the chipset that does not support 64 bit architecture, or do I need to revert to a 32 bit install? My instinct/what I perceive to be the obvious answer, is that yes, my x64 install should/will be able to boot via the bios. My second question is: how do I go about loading Ubuntu once the external is plugged into the iMac?
I just made a very stupid mistake, and in result I just deleted almost everything on my windows 7 partition. I followed this guide: [URL].. for how to access my windows partition from ubuntu and it worked, but then I decided to rm -r the whole thing thinking it was a copy. I have no restore disks or any other type of backup. I know this maybe be impossible, but is there any way to recover my data?
I am backing up may data using Rsync via SSH. I am trying to find a solution that allows me to push my backups from windows and Ubuntu to a Ubuntu server. I don't like the solution that requires my windows machines to have shared drives. Not viable for laptop users that may piggyback on free wireless networks. I would also like a solution that has a GUI for the desktop user but not totally required. I will need a solution that allows me to restore files by date. I do a lot of changes to files on a daily basis and sometimes need an older copy of a file.
I love using Rsync as it is a very simple solution and extremely quick. The only thing I don't know how to do is recover different version of a file. It would be nice to see a visual representation of all the files and different dates of each file. I know I might be asking a little too much, but, it is after all, Linux.
I've planed to install Ubuntu Lucid Lynx 10.04 x64 on my rig. dual boot setup windows 7 preinstalled Intel ICH10R RAID0 manual partition setup 200mb ext3 /boot 2gb swap 100gb ext4 / GUI installer can see my RAID and allows me to create this partitions manually. But when install begins i'm getting error :
Quote: The ext3 file system creation in partition #5 of Serial ATA RAID isw_dgaehbbiig_RAID_0 (stripe) failed
[Code]...
fdisk -l from Live cd shows me separated HDDs without RAID0 wrap (sda and sdb) Also in advanced section where i can configure boot loader default is /dev/sda, which is part of RAId_0. I'm checking isw_dgaehbbiig_RAID_0 as location for loader, assuming that this would be MBR. am i doing this step right?
I have a Raid0 setup (see below for details) connected to the ICH10R raid chip on my Gigabyte EX58-UD4P motherboard. On every second og third boot I get the following error:
Code: udevd-work[157]: inotify_add_watch(6, /dev/dm-1, 10) failed: no such file or directory udevd-work[179]: inotify_add_watch(6, /dev/dm-1, 10) failed: no such file or directory The system halts for a seconds or two and then boots on like nothing has happend.
My setup is as follows:
Two 500gb discs in Raid0 on the ICH10R. The first partition 100 mb is a Windows 7 system partition (gaming etc.) and then a 300gb partition for the actual Windos install. Then Ubuntu 10.10 with /, /home, /swap and then five data partitions. Grub is on the Windows system partition.
Ubuntu 10.10 x64 installed via USB. No problems during install. Besides that I have 2x300gb dics on the Gigabyte built in raid controller. Installed with a Hackintos setup using Mac software raid.My fstab looks like this:
Code: # /etc/fstab: static file system information. # # Use 'blkid -o value -s UUID' to print the universally unique identifier # for a device; this may be used with UUID= as a more robust way to name # devices that works even if disks are added and removed. See fstab(5).
I have a set of Mac software RAID 0 drives that my friend gave me for spring break. I need to access a file on the drive in the Extra folder on one of the drives. It contains some startup settings that need to be changed before I can boot it properly. I loaded up ubuntu and tried to access the drive but only the top level files are readable and when I try to access the Extra folder it says "permission denied." The info on the folder permissions tab is User ID: 501 and Group ID: dialout. Owner permissions = r/w, all other groups/users = none. How can I make Ubuntu read/write to this Extra folder?
I just have a few questions about LVM and RAIDs. It seems they are basically the same thing. Is this correct? I can add two drives together on both of them and it appears as a larger drive, along with other setups like raid1 and raid5, etc.. And is there a difference in performance between them?
And my second question.. I know one is stripped and one is not, but is the performance between a raid1 and a raid0 the same? I've been told that raid1 is faster than raid0 because the data is written twice.. and therefore can be read from two different disks which equals faster read speed, but slower write speed since it writes to the two.
Because of all the trouble with the asrock 939SLi-eSATA2 (see my previous unsolved thread) I have bought a new MSI 790FX-GD70 mobo + processor +ram3 memory and shifted my MSI K9N2-platinum to the asrock box and mothballed the asrock mobo. A rigorous way to solve the problem, but it turned out to be the beginning of more severe trouble. When I try to install Fedora on the striped disks at first everything looks good. Both gparted and the installer see the linux device mapper partitions on the raid config + the unused space.But if I tell the installer to use the unused space, a mere 150 gig, then it tells me:
Could not allocate requested partitions: not enough free space on the disks. The same happens if I try the custom layout. When I start with a small 200 mB ext3 boot partition the same message appears.The ubuntu live cd with dmraid installed and the ubuntu alternate cd do not even see the devmapper partitions. Is the AMD-ATI chip on this new mobo not properly supported by Fedora/Ubuntu?
I want to run Fedora 12 x86_64 on my 2x500GB RAID0 setup, how would I do this via the BIOS method (I want to dual boot Win7 off the same RAID array) with an AMD SB750 southbridge? I'd prefer not to go software, but if I have to I can and just use the 1TB for 7. (I'd prefer not to as the 1TB is a hotswap drive, mostly from PC to External case)
Note: I don't actually have the 1TB Hard Drive or BluRay drive yet, they're still on order)
I searched, but all the results were for Intel's ICH10R or SB600, computer specs are in sig, if there's anything else just say.
I've already got two installs without much problems.. one on my laptop and another fedora13 install on an older comp just to test it a bit before installing it on my main comp. But now I've got a problem. Both those install went without problems but when I started installation on my main comp first I've noticed some graphic problems when there is installation started and there is mouse and fedora 13 welcome installation screen. there are some like glitches or something no idea how to describe them.. like bad pixels in small upper part of the screen. But ignoring that everything went OK up to the part where I can choose a standard discs or non starts like sans and stuff..
When I choose standard disc installation just freeze there. No idea what is happening. Only this that came across my mind is that there is a problem with raid maybe? There are 2x640Gb HDD in raid0, there is win7 installed, and another 1Tb HDD, non-raid member disk, where I would like to install Fedora and have a dual boot. Still got programs that I need win for I'm afraid. Installation went smooth on laptop and another comp but there is no raid so I'm guessing that could be a problem. This comp where installation froze is in short:
When I set up Ubuntu 10.10 I had only one hdd around so I installed my system with the idea that I will add the 2nd hdd for raid1 later on. Last weekend I wanted to add the hdd, but discovered, that ubuntu created a raid0 array. So I went on and tried different things: removing the 1st hdd from the raid0 array, create a raid1 with two disks, and so on... I finally could syncronize both disks but after a reboot the raid0 array appeared again with only one disk. Now I know, I should have written the mdadm.conf and fstab files... My last tries resulted in a missing superblock. Here is the story:
I tore down my old ftp server running FreeNAS because it had some issues. I decided to add a couple more drives and install CentOS on it instead. So now I have 4x 2TB drives that I set up yesterday.OS is installed on a usb flash drive exclusively while I chose to set up the 2TB drives in two stripes and then mirrored, for RAID0+1 instead of RAID1+0.
/dev/md0 = drive 1+2 in RAID0 /dev/md1 = drive 3+4 in RAID0 /dev/md2 = md0+md1 in RAID1
Well, the sync time for these two mirrors of blank drives is almost done, having taken some 15+ hours.I chose this setup to have a single 3.6TB file system mirrored to another 3.6TB for "backup". As this is only going to be a headless ftp server, I don't need massive redundancy/backup. A mirror should suffice if I need to pull some files.So now I'm second guessing myself. I'm wondering if it is even worth it to stripe 2 drives into a single volume with such large sync times. Since data xfer will be over internet, I don't require the massive file writing capacity that would be preferable if it were in my home as a NAS. So, the "performance" increase of RAID0 is not strictly mandatory.
I'm wondering if I should just wipe the drives and set them up in JBOD or LVM instead of RAID0 arrays.In case of boot drive failure, I'd be booting a livecd to xfer files elsewhere or recover the boot drive. So, what difference would I see if I were livebooting to md0, md1, md2 for data viewing as opposed to livebooting to an LVM or JBOD array?As an aside, the drives are WD20EARS, which are 4k sectors which I aligned to start at sector 2048 in fdisk.
I'm looking for some software for syncing lots of data (about 60-90GB) over local network between two machines Ubuntu and Windows XP home.By syncing I mean at least the functionality of auto - copying both ways -> if some file / directory appears on one of the machines it'll be copied to the other.we can assume that files are never modified nor deleted.
